2
Check the wheel lug nut torque to ensure they are properly tightened.
3
Measure rotor thickness using a micrometer to confirm if they are within specification.
4
Perform a test drive to confirm symptoms and assess braking performance.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery (negative terminal) to ensure safety.

Tools Required:

Jack and jack stands
Lug wrench
Brake cleaner
Torque wrench
Micrometer (for rotor thickness measurement)

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using a socket wrench.
Carefully lift the caliper off the rotor and support it using a bungee cord or rope to prevent strain on the brake line.
Remove the brake pads from the caliper bracket.

4. Remove the Brake Rotor

If necessary, remove any retaining screws or clips securing the rotor.
Slide the rotor off the hub. If it's stuck, gently tap it with a rubber mallet to loosen it.

5. Inspect and Replace

Inspection: Check the rotor for warping using a dial indicator. If warped beyond specification, replace the rotor.
Replacement: If needed, install new rotors. Clean the hub surface with brake cleaner before installation.

6. Reassemble Components

Place the new rotor onto the hub.
Reinstall the brake pads into the caliper bracket.
Carefully reposition the caliper over the brake pads and rotor.
Secure the caliper by tightening the mounting bolts to the manufacturer’s torque specifications.

7. Reinstall the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque.
