Summary: The parking brake on a Jeep Grand Cherokee WJ (and similar Wagoneer/Grand Cherokee variants) is a purely mechanical system that holds the rear wheels when parked and provides an emergency backup if the hydraulic brakes fail. This guide explains the components, theory, common failures, safety, and step‑by‑step adjustment procedures for both common rear‑brake arrangements you’ll encounter on WJ models (cable actuated lever on the rear caliper or cable to drum‑in‑hat shoes). Follow safety directions exactly.

What the parking brake does (theory)
- Purpose: holds the vehicle stationary without using hydraulic pressure; provides a mechanical backup.
- How it works: the handbrake lever pulls a cable (main cable) that splits at an equalizer into two rear cables. The rear cables either:
- Pull a small lever on each rear caliper that mechanically squeezes the pad against the rotor (caliper‑actuated parking brake), or
- Activate a small drum‑type shoe assembly inside the rotor “hat” that expands shoes against a drum surface (drum‑in‑hat parking brake).
- Analogy: think of the cable and equalizer like the strings and bridge on a drawbridge — pulling the main cable raises both sides equally to lock the wheels.
- Why adjustment is needed: cables stretch, cables and connections corrode or seize, shoes/pads wear, or adjustment mechanisms freeze. Stretch/wear = more free play at the lever and less holding power.

Major components (what every part does)
- Handbrake lever (inside cabin): ratchet and pawl, release button — user input and locking.
- Release cable (short, under console): links handle to main cable (on some models).
- Main parking‑brake cable: transmits pull from lever to the equalizer.
- Equalizer (junction): splits pull into two rear cables and allows matched tension.
- Rear cables (left and right): connect equalizer to caliper lever or to shoe actuators.
- Caliper parking lever (if caliper‑type): small lever on caliper that converts cable pull to pad clamp force.
- Drum‑in‑hat shoe assembly (if drum‑type): shoes, springs, adjuster — expands and locks inside the rotor hat.
- Cable housings, clips, grommets, brackets, anchor pins: route and anchor the cable.
- Parking‑brake switch/light: indicates when brake is engaged.

Tools and materials
- Wheel chocks, hydraulic jack, jack stands (use stands — never rely on the jack).
- Lug wrench or 19 mm socket (verify your lug size), breaker bar.
- Socket set, ratchet, wrenches (metric/standard as needed), pliers.
- Screwdrivers, needle‑nose pliers, adjustable pliers.
- Penetrant (PB Blaster), wire brush, rags, brake cleaner.
- Grease or anti‑seize for pivot points, small hammer.
- If drum shoes: brake adjusting spoon or small flat screwdriver.
- Torque wrench for wheel lug torque (follow spec for your wheel — typical range ~100–140 ft‑lb; check manual).
- Replacement cables, shoes, springs or caliper parts if needed.

Safety rules (must do)
- Work on a level surface. Chock front wheels securely.
- Jack the rear and place jack stands under the axle or specified lift points; lower vehicle onto stands.
- Test stability before working. Don’t crawl under only on a jack.
- Wear eye protection. Be careful with springs and rusted hardware.
- If you’re unsure of torque specs, consult the factory manual for your model.

Pre‑adjustment inspection
1. Park on level ground, chock front wheels, set transmission in park (or in gear if manual), engine off.
2. Inspect entire cable route: look for frayed cable, stretched outer sheath, rusted brackets/clips, broken return springs, or seized pivot points.
3. With rear wheels raised (on stands) and wheels removed, spin each rear wheel by hand:
- With parking brake released: wheels should spin freely with minimal drag.
- With parking brake applied: wheels should have a firm stopping effect and either won’t turn or will turn with a lot more effort (slight drag is OK).
4. Identify whether your vehicle uses caliper levers or drum‑in‑hat shoes:
- Caliper type: you’ll see a small lever on the rear caliper where the cable attaches.
- Drum‑in‑hat: you will see a backing plate or access slot on the rotor hat and small shoe hardware inside if rotor removed.

Adjustment goals (how tight is right)
- Lever travel: typically around 6–8 clicks or 2–3 inches of handle travel; exact spec varies, but the lever should ratchet solidly and hold without excessive travel.
- Rear wheel drag: with park brake applied, wheels should be hard to turn by hand but not locked solid; with brake released, wheels should spin freely without noticeable drag.
- If you tighten until the wheels cannot rotate, it’s too tight — causes overheating and premature wear.

Adjustment methods (two common setups)

A) Adjusting via the equalizer or under‑console adjuster (most common)
This is the general method when there is a threaded adjuster on the main cable or equalizer.

1. Locate adjuster:
- Under the vehicle along the main cable near the center or under the rear of the center console. It’s a threaded sleeve/locknut where you can tighten the cable.
2. Preparation:
- Release parking brake.
- Raise and support the rear on jack stands, remove rear wheels for access.
3. Loosen the lock nut on the adjuster (if present) so you can turn the adjuster sleeve.
4. With one hand lightly pulling upward on the handbrake lever to the desired number of clicks, use the other hand (or have an assistant) to turn the adjuster to take up slack.
- If alone: pull handbrake to desired position and hold with wire or vice grips on the cable tail (protect the cable with rag). Turn adjuster until tension is felt.
- Turn the adjuster so the rear cables tighten evenly.
5. Test spin each rear wheel: you should feel slight drag when the brake is applied at the desired lever position.
6. Lock the adjuster with the lock nut, or re‑secure adjuster sleeve.
7. Reinstall wheels, lower vehicle, torque lug nuts to spec, test lever travel and parking holding on a slight grade (careful).
8. Final check: parking‑brake light operation and lever release.

B) Caliper lever‑type (adjust caliper mechanism and equalize)
If rear cables pull a lever on each caliper, you still normally adjust at the equalizer/main adjuster (method A). Additionally:
- Inspect caliper lever pivot: clean and lubricate pivot and pin. If the lever is seized, freeing it may restore function.
- If pads or calipers are replaced, ensure lever travel matches equalizer adjustment — you may need to slightly retract pistons with brake tool so the lever’s travel can seat correctly.

C) Drum‑in‑hat shoe adjustment (if applicable)
If your WJ has drum‑in‑hat shoes, there is a shoe adjuster (star wheel) to set shoe clearance.

1. Remove the rear rotor/hat to access shoes, or use the access hole on the backing plate if available.
2. Rotate the star‑wheel adjuster to expand the shoes until they just drag on the drum surface. Then back off slightly until the wheel turns freely with slight resistance.
3. Reassemble rotor, reinstall wheel, lower vehicle, test lever operation and parking holding.
4. Self‑adjusters: note that many self‑adjust when you apply parking brake and reverse; follow service manual if vehicle supports it.

Troubleshooting common problems and fixes
- Cable is frayed or broken: replace the cable assembly (main + both rear cables if necessary). Fraying leads to sudden failure.
- Adjuster threads seized or round: apply penetrant, tap lightly, use correct wrench; if stripped, replace adjuster or entire cable.
- Uneven drag between sides: equalizer misadjusted or one rear cable seized; free/replace the seized cable.
- Lever moves many clicks but no braking: cable stretch/slippage at equalizer or broken/ disconnected cable. Inspect and replace.
- Excessive drag after adjustment: over‑tightened. Back off adjuster until wheels are nearly free.
- Ratchet/pawl damage: if the handbrake handle ratchet teeth are stripped the lever won’t hold — replace the handbrake assembly.
- Caliper lever stuck (corroded pivot): remove caliper, clean pivot, apply grease or replace pivot/lever if damaged.
- Shoes/pads worn: replace pads/shoes and re‑adjust. If pads thin, the equalizer must be tightened to compensate; better to replace worn pads first.
- Parking brake not holding at slope: either not enough adjustment, cable stretching, worn shoes/pads, or a seized component.

What can go wrong if you do this poorly
- Over‑tightening: causes hot spots, premature pad/rotor wear, dragging wheel bearings, and reduced fuel economy.
- Under‑adjusting: insufficient holding power — vehicle may roll.
- Damaged threads or cables from brute force: could require replacement and extra labor.
- Leaving loose hardware: cables can unhook and fail on first use.
- Working without jack stands: severe injury or death. Don’t risk it.

Testing after repair
- Static test on stands: with parking brake set, rear wheels should resist turning.
- Drive test: on a quiet, level area, engage parking brake at low speed to sense if it engages evenly (use brakes conservatively when testing).
- Park on a mild incline to confirm hold; don’t rely only on the parking brake the first few times after a repair — verify while attended.

When to replace components instead of just adjusting
- Severely corroded or frayed cable(s).
- Seized equalizer or adjuster that won’t turn or is bulged.
- Damaged or stripped handbrake lever ratchet.
- Caliper parking lever cracked or seized beyond repair.
- Worn shoes/pads or rotor damage in drum hat assembly.

Quick checklist for a beginner mechanic
- Safety gear and jack stands: check.
- Chock front wheels: check.
- Inspect cables, equalizer, caliper lever/shoes: check.
- Raise vehicle, remove wheels if needed: check.
- Adjust at equalizer to achieve desired lever clicks and wheel drag: check.
- Reinstall wheels, torque lugs, lower vehicle: check.
- Functional test on mild slope: check.

Final notes
- If anything is corroded, seized, or damaged, replace rather than force. Parking brakes are a safety system — don’t gamble.
- If you want exact torque specs, part numbers, or illustrations for your year/trim of WJ, consult the factory service manual or a model‑specific workshop manual.

Done.

These pressure stays inside the catalytic converter or disc coolant opening which permits the inner surface of the piston from the piston as that the best cylinder must be replaced also.

Tools & consumables
- Correct DOT brake fluid for your WJ/WG (check owner’s manual; DOT3 or DOT4 — DO NOT use DOT5). Buy a full extra litre to ensure complete flush.
- Pressure brake bleeder (recommended) or vacuum bleeder/Mityvac or one-way tubing kit and an assistant.
- Clear plastic hose (3–4 mm ID/5–6 mm OD) to fit bleeder nipples, and a catch bottle.
- Bench/hand pump or hand vacuum pump (if not using pressure bleeder).
- 8 mm (or 7 mm/bleeder-specific) box wrench or deep 11 mm spanner depending on bleeder size — use correct fit; flare-nut wrench for line fittings if needed.
- Socket set, ratchet, jack and heavy-duty jack stands, wheel chocks.
- Gloves, safety glasses, clean rags, brake parts cleaner, small brush, drain pan.
- Penetrating oil (PB Blaster) for frozen bleeder screws.
- Torque wrench (for re-torquing banjo bolts etc.).
- New rubber dust caps for bleeders (recommended), replacement bleeder screws if corroded, new copper crush washers for any banjo bolts removed.

Safety & prep
- Work on a level surface, engine off, parking brake engaged, wheels chocked.
- Wear gloves and safety glasses. Brake fluid damages paint and skin — wipe spills immediately with water and brake cleaner, and protect painted surfaces.
- Don’t lean over the reservoir while pressurizing. Avoid open flame.
- Properly dispose of used fluid as hazardous waste.

Overview of methods (pick one)
- Best / fastest: Pressure bleeder on reservoir (15–20 psi).
- Two-person manual: assistant pumps pedal while you open/close bleeders.
- Vacuum bleeder: connects at each nipple and draws fluid while assistant cycles.

Bleeding order
- Start with wheel farthest from master cylinder and proceed to nearest. Typical order for LHD WJ:
1) Rear passenger (right rear)
2) Rear driver (left rear)
3) Front passenger (right front)
4) Front driver (left front)
- If vehicle is RHD, reverse left/right accordingly. Always confirm which side is farthest from master cylinder before starting.

Step-by-step — pressure-bleeder method (recommended)
1) Park and secure vehicle, chock wheels.
2) Remove reservoir cap and clean around it thoroughly to avoid contamination. If using supplied adapter, attach pressure bleeder lid per manufacturer instructions and set regulator to ~15 psi. Do NOT exceed 20 psi.
3) Pre-fill the bleeder tank with fresh DOT3/DOT4 fluid to manufacturer-specified level.
4) Start at the farthest wheel (RR). Remove wheel if needed for access.
5) Fit clear hose over bleeder nipple and place other end into catch bottle containing a little fresh fluid to avoid sucking air back.
6) Crack bleeder dust cap and loosen bleeder screw one turn with correct wrench (if very tight, apply penetrating oil and let sit). Do not use pliers — round screw heads strip easily.
7) Open bleeder slowly. Pressurized fluid from the reservoir will push old fluid and air out. Watch for clear, bubble-free fluid coming through the hose.
8) Close the bleeder screw firmly once only clear fluid appears. Do not allow the reservoir to fall below the MIN mark — top up with fresh fluid as needed during the whole process.
9) Move to next wheel in sequence (LR, RF, LF) and repeat steps 5–8.
10) After final wheel, re-check reservoir level and top up to MAX. Start the engine and pump brake pedal with engine running a few times to seat seals and check firmness. Re-inspect for leaks at bleeder nipples and banjo bolts.
11) Torque any removed bolts (banjo bolts typically ~25–35 ft·lb — check manual) and snug bleeder screws (approx 8–12 ft·lb). Replace bleeder dust caps.
12) Clean up, dispose of used fluid, lower vehicle, and road-test at low speed to confirm firm pedal.

Step-by-step — two-person manual method
1) Same prep as above; keep reservoir cap loose but capped with cloth to prevent splatter.
2) Have assistant pump the brake pedal 3–5 times and hold the pedal down on the last stroke.
3) You open the bleeder nipple, allow fluid and air to escape into hose+catch bottle until flow slows, then close nipple while pedal is still held down.
4) Assistant releases pedal, waits 5 seconds, repeats. Continue until clear, bubble-free fluid appears and pedal is firm. Keep topping up reservoir.
5) Follow same sequence (farthest to nearest). Avoid the assistant “pumping” to the floor repeatedly — always open/close while pedal is held to avoid air ingestion and protect master cylinder.

Step-by-step — vacuum bleeder (single-handed)
1) Attach vacuum pump hose to bleeder nipple and vacuum bottle.
2) Pump to create vacuum; have assistant gently depress brake pedal until firm while you open the bleeder nipple.
3) Keep vacuum applied until clear fluid, then close nipple, release vacuum, repeat. Keep reservoir topped.

How the pressure bleeder tool is used (details)
- The pressure bleeder replaces/locks onto the master cylinder reservoir cap with an adapter. You add fresh fluid to the bleeder tank, pressurize the tank to ~10–15 psi. The tool forces fluid through the brake lines and out the wheel bleeders when opened. It maintains constant positive pressure so one person can do the entire vehicle. Always observe pressure gauge, never exceed 20 psi (excess pressure can damage seals or cause brake fluid to be forced into ABS module).

ABS considerations
- WJ/WG vehicles have ABS. Most pressure-bleeding or manual bleeding will purge ABS via wheel bleeders, but if you still get soft pedal or ABS warning light, you may need to cycle ABS with a scanner that can actuate ABS valves, or perform “pump and hold” cycles per the scanner/manufacturer. If ABS unit has trapped air, a professional scan-tool bleed is required.

Common pitfalls & how to avoid them
- Letting the reservoir run dry: always keep it topped. Running dry draws air into master cylinder, making purging much harder and possibly requiring master cylinder bench bleeding or replacement.
- Using wrong fluid or mixing DOT types: DOT5 silicone is incompatible — use only DOT3/DOT4 as specified.
- Over-pressurizing a bleeder: keep to ~10–15 psi. Excess pressure can damage seals or hose.
- Stripping/breaking bleeder screws: use the correct wrench and apply penetrating oil on seized screws. If a bleeder snaps, you may need to remove caliper/wheel cylinder to extract and replace with new hardware.
- Not following correct sequence: starting at the farthest wheel is important to move air away from master cylinder.
- Ignoring ABS: if ABS light appears or pedal is soft after flush, use scan tool to cycle ABS or seek shop help.
- Contaminating fluid: keep reservoir clean; store bottles closed; do not reuse drained fluid.

Replacement parts commonly needed
- New DOT3/DOT4 brake fluid (1 litre+).
- Bleeder screws (if corroded/rounded); rubber dust caps.
- Copper crush washers for banjo bolts (if you remove hose/caliper banjo bolts).
- Caliper/ wheel cylinder replacement if severely corroded or leaking (only if found during service).
- New master cylinder if leaking or if bench bleeding fails to build firm pedal after correct bleeding.

Torque & tightness notes
- Bleeder nipple: snug only — roughly 8–12 ft·lb. Avoid over-torquing.
- Banjo bolt (brake hose to caliper): typically ~25–35 ft·lb with new copper washers (check manual for exact).
- Always replace crush washers when removing banjo bolts.

Final checks
- Ensure pedal feels firm and consistent with the engine off and with engine running.
- Check for leaks at bleeders, hoses, calipers, and master cylinder.
- Verify reservoir level, reinstall cap, clean any spilled fluid from paint with water and alcohol/brake cleaner.
- Road test at low speed to confirm braking performance and no ABS faults.

Disposal
- Used brake fluid is hazardous. Collect in sealed containers and take to a hazardous waste or recycling center.

That’s the complete procedure. Follow safety steps, keep reservoir filled, use the correct fluid, and work from farthest wheel to nearest.
