Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure the vehicle on jack stands.

3. Remove Wheel Assembly

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the wheel for any debris or damage.

4. Inspect and Service Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor without disconnecting the brake line.
- Remove the old brake pads from the caliper bracket.
- Compare the wear patterns with new pads; replace if necessary.
Caliper Inspection:
- Check for caliper slide pin movement. Clean and lubricate pins if necessary.
- Ensure caliper pistons are retracting properly; replace caliper if sticking.
Brake Rotors:
- Check rotor thickness using a micrometer. Replace if below specifications or if warped.

5. Reassemble

Reinstall new or serviced brake pads and caliper.
Torque caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reattach the wheel and torque lug nuts to specifications (typically 80-100 ft-lbs).

6. Final Checks

Recheck brake fluid level and top off if needed.
Pump the brake pedal to reset the caliper position before driving.
