Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather the necessary tools and parts.
Put on safety goggles and gloves.

2. Inspect and Replace Brake Components

Remove Wheels
- Use a lug wrench to loosen the wheel nuts.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels.
Inspect Brake Rotors
- Visually inspect the brake rotors for signs of warping or scoring.
- Use a dial indicator to measure rotor runout if necessary.
- If rotors are warped, replace them.
Check Brake Pads
- Inspect the thickness of the brake pads.
- Replace if they are worn below the manufacturer's minimum thickness (typically 3mm).
- Clean the caliper and pad mounting surfaces.

3. Inspect Suspension and Steering Components

Check for Wear
- Visually inspect ball joints, tie rods, and control arms for wear or play.
- Replace any worn components.
Alignment Check
- Perform a wheel alignment to ensure proper handling and tire wear.

4. Reassemble and Test

Reinstall Wheels
- Place the wheels back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).
Test Drive
- Conduct a test drive to verify the issue is resolved, checking for any vibrations during braking.
