Solution

1. Preparation

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

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Securely place jack stands under the vehicle to ensure stability.

3. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Remove the wheel using a socket set.
- Check rotors for warping; if warped, replace rotors.
- If replacing, torque new rotors to manufacturer specifications (typically 70-100 ft-lbs).
Inspect Brake Pads:
- Check the thickness of the brake pads; replace if worn below 3mm.
- Clean the caliper bracket and apply brake grease to the pad backing.

4. Wheel Alignment and Balance

Check wheel alignment using an alignment machine.
If out of spec, adjust alignment according to manufacturer specifications.
Balance the wheels if necessary using a wheel balancer.

5. Reassemble and Lower Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

6. Test Braking System

Start the vehicle and test the brakes in a safe area to confirm the issue is resolved.
