Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Disconnect the battery before working on the braking system.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a jack and jack stands.
2. Remove the caliper bolts using a socket set.
3. Slide the caliper off the rotor and support it without straining the brake line.
4. Remove old brake pads from the caliper bracket.
5. Compare new pads with old ones; replace if worn below manufacturer’s specifications.
6. Apply brake grease to the back of the new pads and install them.

3. Resurface or Replace Brake Rotors

Sub-steps:
1. If rotors are warped, remove them from the hub.
2. Use a dial indicator to measure rotor runout; if out of spec, either resurface or replace.
3. Clean the new or resurfaced rotors with brake cleaner to remove any residue.
4. Install the rotors back onto the hub and torque to manufacturer specifications.

4. Reassemble Brake Components

Sub-steps:
1. Reattach the caliper over the new or resurfaced rotor.
2. Tighten caliper bolts to the specified torque.
3. Reinstall the wheel and torque lug nuts to the manufacturer’s specifications.
4. Repeat the process for the other side if necessary.
