Solution

1. Preparation

Gather tools and materials:
- Jack and jack stands
- Lug wrench
- Socket set
- Brake cleaner
- Torque wrench
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Remove Wheel Assembly

Loosen lug nuts slightly before raising the vehicle.
Jack up the vehicle and secure it with jack stands.
Remove the wheel assembly using a lug wrench.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using the socket set.
Carefully slide the caliper off the rotor without damaging the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper slides and lubricate them if necessary.
Install new brake pads in the caliper bracket ensuring proper orientation.
Use a brake caliper tool to compress the caliper piston if needed.

4. Check and Replace Rotors (if necessary)

Inspect the rotors for any signs of warping. If warped, replace them.
If replacing, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install new rotors, ensuring they are secured properly.

5. Reassemble and Reinstall

Reattach the caliper over the new brake pads and rotor.
Torque caliper bolts to specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

6. Final Checks

Pump the brake pedal to ensure the caliper piston is seated properly.
Check brake fluid level and add if necessary.
