Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is still on the ground.
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

Check brake pads for thickness; replace if below manufacturer specifications.
Inspect rotors for grooves, cracks, or warping.
- If warped, they should be resurfaced or replaced.
Ensure calipers move freely; lubricate slides if necessary.

4. Replace or Resurface Rotors

If rotors are warped beyond specification:
- Remove caliper bracket bolts and remove the caliper.
- Unbolt the rotor from the hub if necessary.
- Install new rotors or take old rotors to a machine shop for resurfacing.
- Torque rotors to manufacturer specifications if applicable.

5. Reassemble Components

Reinstall the caliper and ensure proper torque on bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from jack stands and fully tighten lug nuts in a star pattern.

6. Test Drive

Start the vehicle and gently apply the brakes to check for any vibrations.
Monitor brake performance for smooth operation.
