Tools Required

Jack and jack stands
Lug wrench
Brake pad thickness gauge
Torque wrench
Brake cleaner
C-clamp or brake caliper tool
Socket set
Screwdriver set
Brake fluid

Repair Instructions

For Worn Brake Pads or Rotors

Raise the Vehicle
- Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the Wheel
- Use a lug wrench to loosen and remove the lug nuts, then take off the wheel.
Remove the Brake Caliper
- Locate the caliper bolts and remove them using a socket. Slide the caliper off the rotor and support it with a hanger to avoid straining the brake line.
Remove Old Brake Pads
- Slide out the old brake pads from the caliper bracket.
Inspect Rotors
- Check the rotors for wear and warping. If warped, replace or resurface them.
Install New Brake Pads
- Place new brake pads in the caliper bracket. Ensure they are positioned correctly.
Compress the Caliper Piston
- Use a C-clamp or brake caliper tool to compress the caliper piston back into the housing.
Reinstall the Caliper
- Position the caliper over the new brake pads and secure it with the caliper bolts. Torque to manufacturer specifications.
Reattach the Wheel
- Place the wheel back on and hand-tighten the lug nuts.
Lower the Vehicle
- Remove the jack stands and lower the vehicle.
Torque Wheel Nuts
- Once the vehicle is on the ground, torque the lug nuts to the manufacturer’s specifications.
Test Brake Function
- Pump the brake pedal a few times to seat the pads before driving. Check for any unusual noises or issues.

For Brake Fluid or Air in the System

Check Brake Fluid Level
- If the fluid is low, top it up with the recommended brake fluid.
Bleed the Brakes
- Using a brake bleeder kit, start with the rear brakes. Attach a tube to the bleeder valve on the caliper, and have an assistant press the brake pedal while you open the valve to release air bubbles. Close the valve before the pedal reaches the floor. Repeat until no air bubbles are present.

Conclusion

Regular inspection and maintenance of the rear brake system are crucial for the safe operation of the Toyota Camry XV70. Addressing the symptoms early can prevent more significant issues and ensure optimal braking performance. Always consult the vehicle’s service manual for specific torque specifications and procedures.
