Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.

2. Raise and Secure the Vehicle

Use a jack to lift the front or rear end of the vehicle, depending on which brakes are affected.
Secure with jack stands to ensure safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Rotors (if warped)

Remove the caliper by unbolting it from the bracket (use a socket set).
Support the caliper with a bungee cord or similar to avoid straining the brake line.
Remove the brake rotor by unbolting it or by gently tapping it with a rubber mallet if it is stuck.
Install the new rotor, ensuring it is properly seated.

5. Inspect and Replace Brake Pads (if worn)

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads into the bracket.

6. Reassemble and Torque

Reattach the caliper over the new pads and rotor.
Torque caliper bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

7. Lower the Vehicle and Finalize

Carefully lower the vehicle and remove the jack stands.
Torque the lug nuts to the proper specification (typically around 90-100 ft-lbs).
