Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the 12V battery for safety.

2. Wheel and Brake Assembly Removal

Tools Required: Socket set, jack stands, lug wrench.
Loosen the lug nuts on the front or rear wheels.
Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, brake rotor puller (if necessary).
Check the rotors for warping using a dial indicator or by visual inspection.
If warped, remove the brake caliper by unbolting it and hanging it with a wire (do not let it dangle on the brake line).
Remove the old rotor and install a new rotor, ensuring it is properly aligned.
Torque the caliper bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Check the condition of the brake pads for uneven wear.
If worn, remove the old pads from the caliper bracket.
Lubricate the sliding surfaces of the new brake pads with anti-squeal grease.
Install the new brake pads into the caliper bracket.

5. Reassemble and Test

Tools Required: Torque wrench.
Reinstall the brake caliper and wheels.
Torque the lug nuts to the recommended specifications.
Lower the vehicle and reconnect the battery.
Perform a test drive to verify the repair.
