Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly before jacking up the vehicle.
Safely lift 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

Brake Pads:
- Check the thickness of the pads; replace if below manufacturer specifications.
Brake Rotors:
- Measure rotor thickness with a micrometer; compare with specifications.
- Look for signs of warping using a dial indicator or by spinning the rotor.
- If warped, replace the rotor.
Calipers:
- Ensure calipers are not sticking and are functioning correctly.

4. Replace Brake Pads and Rotors (if necessary)

If replacing pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and hang it securely (do not let it dangle by the brake line).
- Remove old pads and install new pads in reverse order.
If replacing rotors:
- Remove the old rotor (may require tapping with a hammer if stuck).
- Install the new rotor and secure it with the appropriate torque specifications.

5. Reassemble Wheel

Place the wheel back on the hub.
Hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

6. Test Drive

Conduct a test drive to ensure the issue is resolved and check for vibrations during braking.

Tools Required:

Jack and jack stands
