Solution

1. Preparation

Gather tools and parts: brake cleaner, socket set, torque wrench, jack, jack stands, and replacement brake pads if necessary.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.

2. Remove Wheel

Use a jack to lift the vehicle and place it securely on jack stands.
Remove lug nuts using a socket wrench and take off the wheel to access the brake assembly.

3. Inspect and Clean Brake Components

Spray brake cleaner on the brake pads and rotors to remove dust and debris.
Use a wire brush to gently clean the brake caliper and bracket.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket wrench, then slide the caliper off the rotor.
Remove old brake pads from the caliper bracket; note the orientation for installation of new pads.
Install new brake pads into the caliper bracket, ensuring they are seated correctly.

5. Reassemble Brake Components

Replace the caliper over the new pads and secure it by tightening the caliper bolts to the manufacturer’s torque specification (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle off the jack stands and remove the jack.
Tighten lug nuts to the manufacturer’s specification in a star pattern.
Test the brakes by gently pressing the pedal to seat the pads before driving.
