Solution

1. Preparation

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

2. Remove Wheel

Using a lug wrench, loosen the lug nuts of the wheel associated with the braking issue.
Lift the vehicle using a jack and securely place jack stands under the vehicle frame.
Completely remove the lug nuts and wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor, supporting it to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing for signs of wear; if pads are worn below the manufacturer's specification, replace them.
Apply brake grease to the back of the new pads to reduce noise.
Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or scoring.
If the rotor is damaged or below thickness specifications, remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
Install a new rotor by aligning it with the hub and securing it with screws.
Make sure to clean the new rotor with brake cleaner to remove any protective oil.

5. Reassemble Brake Components

Reposition the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque setting (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Remove jack stands and lower the vehicle.
Tighten lug nuts to the manufacturer’s specified torque setting (usually 76-80 ft-lbs).
Pump the brake pedal a few times to ensure proper brake pad seating before driving.
