Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear appropriate safety gear (gloves and goggles).

2. Remove Wheel

Loosen the lug nuts on the wheel corresponding to the affected brake.
Raise the vehicle using a jack and support it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the bolts securing it using a socket set.
Carefully slide the caliper off the brake rotor, supporting it to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket. Inspect them for wear; replace if less than 1/8-inch thick.
Clean the caliper bracket and apply brake grease to the contact points of the new pads.
Install the new brake pads in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the surface of the brake rotor for any scoring or uneven wear.
If the rotor is damaged, remove the caliper bracket and rotor by removing the retaining screws.
Install new rotors, ensuring they are properly seated on the hub.
Reattach the caliper bracket and tighten bolts to manufacturer-recommended torque specifications (typically around 25-35 lb-ft).

5. Reassemble and Test

Slide the caliper back over the new brake pads and rotor, securing it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically around 80-100 lb-ft).
Pump the brake pedal a few times to ensure proper engagement before driving.
