Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, brake cleaner, and jack stands.
Ensure the vehicle is on a flat surface and turn off the ignition.
Disconnect the battery to ensure safety while working on the brakes.

2. Remove Wheel

Loosen the lug nuts on the wheel where the vibration is felt.
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by unscrewing the bolts holding it in place.
- Inspect the brake pads for wear; replace if below the minimum thickness (usually around 3mm).
Brake Rotors:
- Check the rotor surface for warping or grooves; replace if damaged.
- Measure the rotor thickness with a micrometer; ensure it meets manufacturer specifications.

4. Replace or Repair Components

If brake pads or rotors are worn, replace them:
- Install new brake pads by sliding them into the caliper bracket.
- For rotors, unbolt the old rotor and install the new one, ensuring proper alignment.
Reinstall the brake caliper and torque the bolts to the manufacturer’s specifications.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the battery and test the brakes by gently applying pressure to ensure proper function.
