Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Inspect and Remove Wheels

Tools Required: Jack and jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts on the front wheels while the vehicle is on the ground.
2. Lift the vehicle with a jack and secure it with jack stands.
3. Remove the front wheels completely.

3. Inspect Brake Components

Tools Required: Torque wrench, dial indicator.
Sub-steps:
1. Inspect the brake rotors for warping using a dial indicator; replace if warping exceeds specifications.
2. Measure the thickness of the brake pads; replace if below the minimum thickness.
3. Clean the rotor surface with brake cleaner if necessary.

4. Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench.
Sub-steps:
1. If rotors are warped, remove the caliper bolts and slide off the caliper.
2. Remove the old rotor and install the new rotor, ensuring proper alignment.
3. Reinstall the caliper and torque the bolts to manufacturer specifications.
4. Replace brake pads by sliding them into the caliper bracket and ensuring proper fit.

5. Reassemble and Test

Tools Required: Lug wrench, torque wrench.
Sub-steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the specified value.
3. Test drive the vehicle to ensure the vibrations have been eliminated.
