Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

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

3. Inspect and Replace Brake Components

Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully lift the caliper and support it using a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Compare new pads with old ones for thickness; install new pads in the same position as the old ones.

Brake Rotors

Check the rotor for wear; if damaged, remove it by unscrewing the retaining screws if present.
Clean the hub surface with brake cleaner.
Install new rotors by aligning with the bolt holes and securing them.

4. Reassemble Components

Reattach the caliper over the new brake pads.
Torque the caliper bolts to the manufacturer's specifications (typically around 20-30 ft-lbs).
Reinstall the wheel, hand-tighten the lug nuts, and lower the vehicle.

5. Final Checks

Tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).
Pump the brake pedal several times to seat the brake pads.
Test the brakes at low speed to ensure proper function.
