Important safety information - read before proceeding

•Always allow the brakes to cool before working on them.
•Ensure the vehicle is securely supported on jack stands before working underneath.

Symptoms

•Grinding or squeaking noise when brakes are applied
•Reduced braking efficiency
•Vibration or pulsation felt in the brake pedal
•Warning light illuminated on the dashboard
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect the rear brake pads for wear and thickness using a visual inspection.
2
Check for any debris or foreign objects lodged between the brake pads and rotor.
3
Measure rotor thickness with a micrometer to ensure they are within manufacturer specifications.
4
Examine the brake calipers for proper operation and inspect for any leaks or damage.
5
Use an OBD-II scanner to check for any related error codes if the warning light is illuminated.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Use wheel chocks to secure the front wheels.

2. Remove the Rear Wheel

Loosen the lug nuts on the rear wheel using a socket wrench.
Raise the vehicle with a jack and secure it on jack stands.
Completely remove the lug nuts and take off the rear wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the brake caliper by unbolting it using a socket wrench (torque specifications: typically 25-30 Nm).
- Slide the caliper off the rotor and support it using a bungee cord or rope to avoid stressing the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper slides and clean them if necessary.
- Install new brake pads, ensuring they are oriented correctly and seated properly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- If rotors are worn beyond specification, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
- Clean the hub surface with a wire brush to remove rust or debris.
- Install new rotors, ensuring they are seated properly and secure with retaining screws (torque specifications: typically 10-15 Nm).

5. Reassemble Components

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque (25-30 Nm).
Reinstall the rear wheel, tightening the lug nuts in a star pattern to ensure even seating (torque specifications: typically 80-100 Nm).

6. Final Checks

Lower the vehicle and remove wheel chocks.
Pump the brake pedal several times to seat the brake pads before driving.
Check brake fluid level in the master cylinder and top off if necessary.
