Solution

1. Preparation

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

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are below manufacturer specifications, replace them.
Replace:
- Remove the caliper bolts with a socket wrench.
- Carefully lift the caliper and support it with a bungee cord or rope to avoid straining the brake line.
- Remove old brake pads and install new ones, ensuring they are properly seated.
- Reattach the caliper and torque bolts to manufacturer specifications.

4. Inspect and Resurface/Replace Rotors

Inspect: Check for rotor warping using a dial indicator or visual inspection.
Resurface: If within tolerance, machine the rotors to ensure a flat surface.
Replace: If warping exceeds tolerance:
- Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor and torque screws to specifications.

5. Reassemble and Adjust

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
Repeat for all wheels if necessary.
