Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and set the parking brake.
Gather tools and parts needed for the repair.

2. Remove Wheel

Use a lug nut wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Rotors

Inspection: Check for signs of warping by measuring rotor thickness with a micrometer; look for grooves or cracks.
Replacement:
- If rotors are warped or worn beyond specifications, remove the caliper by unscrewing the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
- Remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
- Install new rotors, ensuring they are seated properly and secure any retaining screws.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Measure the thickness; if below specifications, replace with new pads.
Apply brake grease to the backing of the new brake pads.
Reinstall the new pads and ensure they are properly seated in the caliper bracket.

5. Reassemble and Lower Vehicle

Reattach the caliper over the new pads and torque caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
