Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent the vehicle from rolling.
Safety warning: Disconnect the battery if working with electronic brake components.

2. Remove Wheel

Loosen the lug nuts on the wheel with the affected brakes.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor; do not disconnect the brake line.
- Check the brake pads for thickness and wear indicators.
Replace Brake Pads (if necessary):
- If pads are worn down (less than 3mm), remove them from the caliper bracket.
- Install new brake pads into the caliper bracket.

4. Inspect and Resurface or Replace Rotors

Inspect Rotors:
- Check for scoring, warping, or uneven surfaces.
Resurface or Replace Rotors (if necessary):
- If the rotors are scored but within specifications, resurface them using a brake lathe.
- If excessively worn or damaged, replace with new rotors.

5. Reassemble Components

Reinstall the caliper over the new brake pads, ensuring it seats properly.
Torque the caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Reinstall the wheel and lug nuts, and torque the lug nuts to the proper specifications (typically 76-85 ft-lbs).

6. Final Checks

Reconnect the battery if it was disconnected.
Pump the brake pedal to seat the pads against the rotors.
Check brake fluid level and add fluid if necessary.
