Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheels

Loosen the lug nuts on the affected wheels slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to check for rotor warping (should be within manufacturer specifications).
Replacement (if warped):
- Remove the caliper bolts and slide the caliper off the rotor.
- Remove the rotor by unscrewing any retaining screws (if applicable).
- Install new rotors, ensuring they are tightened to the manufacturer’s torque specifications.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect for thickness; replace if they are below the manufacturer’s minimum thickness.
Apply brake grease to the backing of the new pads and install them in the caliper bracket.

5. Reassemble and Torque

Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specifications.
Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.

6. Test Drive

Perform a test drive to ensure normal braking operation and to check for any vibrations.
