Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly using a socket set while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the wheel completely.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set and slide the caliper off the rotor.
2. Remove old brake pads; note their orientation for the new pads.
3. Inspect the caliper for sticking or damage.
4. Install new brake pads, ensuring they are positioned correctly.
5. Reattach the caliper and torque the bolts to manufacturer specifications (typically around 25-35 ft-lbs).

4. Inspect and Resurface or Replace Rotors

Sub-steps:
1. Check rotor surface for scoring or warping using a dial indicator.
2. If warped, either resurface the rotors or replace them.
3. If replacing, remove the rotor by unscrewing the retaining screws (if present) and sliding off the rotor.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically around 75-85 ft-lbs).
3. Perform a test drive to verify the repair.
