Uneven Rear Brake Wear on a 2022 Toyota Camry XV70

Symptoms:

One rear brake pad wears down faster than the other.
Noticeable noise (squeaking or grinding) coming from one side when braking.
Vehicle pulls to one side during braking.
Reduced braking efficiency from the affected wheel.

Possible Causes:

Brake Caliper Issues
- Sticking or seized caliper on one side.
- Improper caliper slide pin lubrication.
Brake Pad Quality or Compatibility
- Using mismatched or low-quality brake pads.
- Inconsistent material composition in pads.
Brake Rotor Condition
- Unevenly worn or warped rotors can cause uneven pad wear.
- Corrosion or rust buildup affecting pad contact.
Suspension Issues
- Misaligned rear suspension components.
- Worn suspension bushings or components affecting brake alignment.
Brake Hose Problems
- A collapsed brake hose leading to uneven pressure distribution.
- Old or damaged hoses affecting fluid flow.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Caliper gauge or micrometer
Brake cleaner
Lubricant (high-temperature brake grease)
Socket set
Pliers
Inspection mirror (optional)

Repair Instructions:

Step 1: Lift the Vehicle

Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the rear wheels slightly.
Use the jack to lift the vehicle and secure it with jack stands.

Step 2: Remove Rear Wheels

Fully remove the lug nuts and take off the rear wheels for access to the brakes.

Step 3: Inspect Brake Components

Brake Pads:
- Remove the caliper by unbolting it from the bracket.
- Inspect the brake pads for uneven wear. If one is significantly thinner, it may need replacement.
Brake Rotors:
- Check the rotor surface for grooves or warping. If warped, consider resurfacing or replacing.
Caliper:
- Check caliper slide pins. Clean and lubricate if necessary.
- Ensure the caliper piston moves freely without resistance.

Step 4: Brake Hose Check

Inspect the brake hoses thoroughly for signs of damage.
If any issues are found, replace the brake hoses as needed.

Step 5: Suspension Inspection

Examine all suspension components for wear or damage.
Replace any worn components or have the alignment checked by a professional.

Step 6: Brake Pad Replacement

If pads are worn unevenly, replace both pads on the affected axle to maintain balance.
Apply high-temperature brake grease to the back of the new pads and caliper slide pins.
Reinstall the caliper, ensuring it is securely fastened.

Step 7: Reassemble and Test

Reinstall the rear wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Pump the brake pedal several times to ensure proper brake engagement.
Test drive the vehicle to check for improved brake performance and any pulling or noise.

Conclusion

Uneven brake wear can be caused by several factors. Systematic inspection and addressing the root cause will ensure the longevity of your brake system and safe vehicle operation. If issues persist after performing these diagnostics and repairs, consider consulting a professional technician for further assistance.
