Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to ensure safety.

2. Raise the Vehicle

Use a jack to elevate the vehicle and secure it on jack stands.
Remove the wheel covering the affected brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for wear; replace if they are below the manufacturer’s minimum thickness (usually around 3mm).
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper orientation and fit.
- Use brake grease on the backing of the pads to minimize noise.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for grooves or uneven surfaces on the rotor.
- Measure rotor thickness to ensure it is within specifications.
Replace Rotors:
- If rotors are damaged or worn, remove the caliper bracket.
- Detach the rotor from the hub by removing the retaining screws.
- Install new rotors, ensuring they are clean and free from oil.
- Reattach the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure it with the caliper bolts, tightening to manufacturer specifications (typically 25-35 ft-lbs).
Reattach the wheel and lower the vehicle.
Reconnect the battery.
