Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel and Brake Components

Tools Required: Socket set, jack, jack stands, lug wrench.
Loosen the lug nuts on the affected wheel.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel by fully loosening and taking off the lug nuts.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid straining the brake line.
Remove the worn brake pads from the caliper bracket.
Tools Required: Brake pad spreader tool (optional).
Install new brake pads, ensuring they are correctly aligned and seated.

4. Inspect and Replace Brake Rotors

Check the rotor for warping or scoring. If damaged, replace the rotor.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Clean the hub surface with a wire brush to ensure a smooth fit for the new rotor.
Install the new rotor, ensuring it is aligned properly.

5. Reassemble and Test

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specification (typically around 80-100 ft-lbs).
