Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Wheel Removal

Loosen the lug nuts on the wheel corresponding to the affected brake.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and wheel.

3. Brake Pad Inspection and Replacement

Remove the brake caliper bolts using a socket set.
Carefully lift the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for uneven wear; replace if necessary.
If replacing, install new brake pads, ensuring they are seated properly in the caliper bracket.

4. Brake Rotor Inspection and Resurfacing/Replacement

Inspect the brake rotor for signs of warping or scoring.
If warped, measure runout with a dial indicator; if excessive, replace the rotor.
If the rotor is within acceptable limits but scored, resurface it using a brake lathe.
Install the rotor back onto the hub if resurfaced or replace it with a new one.

5. Reassembly

Reattach the brake caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (usually around 25-35 lb-ft).
Reinstall the wheel and tighten lug nuts in a star pattern to the specified torque (generally 80-100 lb-ft).
Lower the vehicle from the jack stands.

6. Brake Fluid Check and Bleeding

Check the brake fluid level in the master cylinder; top off with the appropriate fluid type if low.
Bleed the brakes to remove any air in the system, starting with the brake furthest from the master cylinder and working to the closest.
