Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Brake Rotors

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts using a socket set and take off the wheel.
Examine Rotors:
- Check the rotor surface for warping or grooves. If warped, measure with a dial indicator.
Replace Rotors (if necessary):
- Remove the caliper bracket bolts with a socket and slide the caliper off.
- Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
- Install the new rotor, ensuring it is properly aligned and secured.

3. Inspect and Replace Brake Pads

Examine Brake Pads:
- Remove the caliper and check the brake pads for thickness and uneven wear.
Replace Brake Pads (if required):
- If the pads are worn down, remove them from the caliper bracket.
- Install new pads, ensuring they are seated properly in the bracket.

4. Reassemble and Test

Reattach Components:
- Reinstall the caliper over the new pads and secure the caliper bracket bolts to the manufacturer’s torque specifications.
- Reinstall the wheel and lug nuts, tightening them in a star pattern.
Lower Vehicle:
- Remove jack stands and lower the vehicle back to the ground.
Reconnect Battery:
- Reconnect the negative battery terminal.
