Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.
Disconnect the battery to eliminate electrical hazards.

2. Remove Wheel Assemblies

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect brake rotors for warping or grooves. Use a straightedge to check for flatness.
Check brake pads for thickness and even wear. Replace if they are worn down to the indicator.

4. Replace Rotors (if warped)

Tools Required: Torque wrench, socket set
Remove the caliper by unbolting it from the bracket. Secure it with a bungee cord to avoid stress on the brake line.
Remove the old rotor by taking off any retaining screws or clips.
Install the new rotor, ensuring it is seated properly.
Reattach the caliper and torque bolts to the manufacturer’s specifications.

5. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new pads to prevent noise.
Install the new brake pads in the caliper bracket.
Reinstall the caliper and ensure it is securely fastened.

6. Reassemble Wheel and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery and perform a test drive to verify the repair.
