Toyota B 2B engine factory workshop and repair manual digital

- Safety first (read before touching anything)
- Wear safety glasses and gloves to protect from brake dust and fluids.
- Work on a level surface, engage the vehicle in Park (or in gear for manual), and set front wheel chocks.
- Use a quality hydraulic jack and rated jack stands; never rely on the jack alone to hold the car.
- Do not breathe brake dust; use a damp rag or brake cleaner to minimize airborne dust.
- If you are unsure at any step, stop and have a qualified mechanic do the job.

- Overview of what “parking brake adjustment” means for most Toyotas
- Parking brakes usually actuate the rear wheels via a cable and either shoes inside a drum, or a small drum inside the rear disc hat (drum-in-hat).
- Adjustment takes up cable slack so the lever/pedal travel is correct and the brake holds the car on a slope.
- Some Toyota models have an automatic adjuster; others have a manual star-wheel adjuster accessible from the wheel or under the car.

- Tools you’ll need (basic tools + why each is required) — detailed descriptions and how to use them
- Wheel chocks
- Why: prevent the vehicle from rolling when jacked.
- How to use: place snugly against front wheels if working on rear, or rear wheels if working on front.
- Hydraulic floor jack (2-ton minimum recommended)
- Why: lifts the car so you can access rear wheels or adjusters.
- How to use: position under the manufacturer’s jacking point, pump handle to lift, lower by turning release slowly.
- Jack stands (pair, rated for your vehicle)
- Why: safely supports the vehicle once lifted.
- How to use: set to the same height as jacked position, lower car slowly onto stands—never work on a car supported only by the jack.
- Lug wrench or impact wrench with correct socket (usually 19 mm / 21 mm depending on model)
- Why: remove rear wheel if needed to access adjuster or drum.
- How to use: break lug nuts loose before jacking, then remove nuts and wheel once car is off the ground.
- Ratchet and socket set (10–19 mm common sizes)
- Why: remove inspection covers, adjuster access brackets, or cable anchor bolts.
- How to use: choose correct socket, use ratchet or breaker bar for tight bolts.
- Flat-blade screwdriver or pry bar
- Why: pop off rubber access plug on backing plate or lever clips.
- How to use: gently pry—not force—to avoid damaging plugs.
- Pliers (needle-nose and regular)
- Why: hold/turn small springs, clips, or adjuster wheel.
- How to use: use correct jaw for grip, don’t use pliers as wrenches on bolts.
- Brake spoon / star-wheel adjuster tool (or a flat screwdriver if necessary)
- Why: turns the star-wheel adjuster inside the drum/backing plate to take up slack.
- How to use: engage the star wheel teeth and rotate — direction may vary by model (usually tighten by turning so shoes expand outward).
- Torque wrench
- Why: properly torque wheel nuts and any bolts you remove to manufacturer specs (safety).
- How to use: set desired torque, tighten nuts in a crisscross pattern to spec.
- Penetrating oil (e.g., PB Blaster)
- Why: frees rusted adjuster or cable components.
- How to use: spray, let soak 10–15 minutes, then work parts free.
- Brake cleaner and rags
- Why: remove brake dust/grease for inspection; cleaner also used to remove oil/grease from shoes or drum.
- How to use: spray parts outdoors or in well-ventilated area; wipe with rags.
- Wire brush
- Why: clean rust from adjuster threads and anchor points.
- How to use: brush lightly to remove loose rust—don’t gouge metal surfaces.
- Flashlight or inspection light
- Why: helps you see the adjuster inside drum or backing plate.
- How to use: position to illuminate the star-wheel area.
- Replacement parts (if needed—see section below)
- Why: worn cables, shoes, or hardware cause poor parking brake performance.
- How to use: specific replacement procedures vary—some require partial brake disassembly.

- Basic adjustment procedure (generalized for common Toyota rear drum or drum-in-hat parking brakes)
- Prepare vehicle
- Chock front wheels, set parking brake off, loosen rear lug nuts slightly if you plan to remove wheels.
- Jack rear of vehicle and support on jack stands at the recommended lift points.
- Access the adjuster
- If there’s an external adjuster access hole in the backing plate or dust plug on the hub, remove the rubber plug with a screwdriver.
- If no access hole or you have disc/drum-in-hat, remove the rear wheel and, if necessary, the drum or the brake rotor hat cap to reach the adjuster.
- Identify the star-wheel adjuster
- Look for a small toothed wheel (star wheel) between the brake shoes or behind the rotor hat; it will have an access slot or flat surface to turn.
- Adjust the star wheel
- With the parking brake OFF (lever fully down/pedal released), turn the star wheel to reduce play (turn direction that expands shoes outward).
- Periodically spin the wheel/rotor by hand; when shoes just begin to drag slightly (light, even drag), stop. That’s the correct adjustment range.
- If you over-tighten (hard drag or wheel won’t spin), back the star wheel off a click or two until slight drag returns.
- Check lever/pedal travel
- With vehicle on ground and wheels torqued, operate parking brake lever/pedal and count clicks or measure travel—consult your vehicle manual for target travel (typical: 4–7 clicks on handbrake).
- If travel is still excessive after star-wheel adjustment, the cable may need tightening at the equalizer under the car or at the lever boot (some Toyotas have an in-cabin adjuster nut).
- Final checks
- Lower car from jack stands, torque lug nuts to spec, test the parking brake on a gentle incline (with chocked front wheels for safety) to confirm it holds.
- Reinstall access plugs and ensure all tools and loose parts are cleared from underneath the car.

- How to use specific tools during the process (short practical notes)
- Brake spoon / star-wheel tool: insert the hooked end into the star-wheel teeth and rotate; the small hooked tip lets you turn the wheel without poking fingers into springs.
- Prying off dust plug: wedge screwdriver under plug edge and twist gently; don’t gouge backing plate.
- Using penetrating oil: spray on the adjuster and pivot points, wait, then tap gently with a hammer if stuck—don’t force heavy twisting without oil.
- Using jack and stands: raise slowly, place stands under solid pinch weld or frame, lower jack until weight is on stands, give car a small nudge to confirm stability.

- When parts replacement may be required, why, and what replacement parts you might need
- Parking brake cable(s)
- Why replace: frayed, rusted, seized, or stretched cables cause excessive pedal travel or uneven braking.
- Replacement part: OEM or good-quality aftermarket parking brake cable(s) specific to your Toyota model/year and axle side.
- Brake shoes or parking brake shoes (for drum-in-hat or drum brakes)
- Why replace: worn shoes won’t expand enough to hold; glazing from heat reduces friction.
- Replacement part: rear brake shoe set for your model (some cars have specific shoes for parking function).
- Hardware kit (springs, pins, clips, retainers)
- Why replace: springs weaken or corrode; new hardware ensures correct tension and function.
- Replacement part: backing plate hardware kit matched to your rear brake type.
- Drum or rotor (if drum-in-hat inner surface)
- Why replace/turn: scored, out-of-round, or excessively thin drums/rotors reduce hold and cause noise/vibration.
- Replacement part: brake drum or rotor (or machining if within spec), plus reassembly components.
- Equalizer or adjuster mechanism
- Why replace: stripped threads or seized adjusters prevent proper cable tensioning.
- Replacement part: adjuster assembly or equalizer link specific to model.
- Notes on choosing parts
- Use OEM or quality aftermarket parts for safety; cheaper cables or shoes may wear faster.
- If one cable failed from rust, replace both sides to ensure balanced braking.

- Signs that adjustment won’t fix it and replacement/repair is required
- Parking brake lever/pedal still has excessive travel after correct adjustment.
- Wheel still spins freely with parking brake applied and star wheel at its limit.
- Visible fraying, rust-through, or seized sections of cable.
- Uneven engagement between left and right rear brakes.
- Grinding, dragging, or abnormal noises after adjustment.
- In these cases, replace the cable, shoes, or seized parts rather than relying on adjustment.

- Quick troubleshooting tips
- If left and right rear brakes adjust differently, inspect both cables and equalizer for binding or corrosion.
- If the adjuster won’t turn, apply penetrating oil and tap lightly; replace if threads are stripped.
- If parking brake holds when wheels are off but not on the ground, recheck the cable free-play and final adjustment with vehicle weight on wheels.

- Final safety/test checklist
- Re-torque wheels to manufacturer spec.
- Test parking brake on a gentle, controlled incline with a helper—car must hold without engine power.
- Re-check lever/pedal feel; if it’s very stiff or very loose, re-inspect for binding or cable damage.
- Dispose of old brake dust and parts per local regulations.

- If you prefer not to replace parts yourself or the system is corroded or seized
- Why: brake systems are safety-critical; professional shops have presses, specialty tools, and lift access to correctly service or replace cables, shoes, drums, and adjusters.
- What a shop can do: fully disassemble, clean/replace rusted components, measure drums/rotors and re-machine or replace to spec, bleed or lubricate mechanisms.

- Typical replacement part names you may need to order (confirm with vehicle VIN/year)
- Rear parking brake cable (left and/or right)
- Rear brake shoe set or rear brake shoe (parking)
- Parking brake hardware kit (springs, clips)
- Backing plate or adjuster assembly (if damaged)
- Rear drum or rotor (if worn beyond spec)

- Final note
- Adjusting is often straightforward with the right access and tools, but if you encounter seized cables, stripped adjusters, or deep rust, replacement and/or professional help will be required for safety.
