Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen lug nuts slightly while the vehicle is on the ground.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels using a socket set to take off the lug nuts.

3. Inspect and Replace Brake Components

A. Inspect Brake Pads and Rotors

Remove the caliper bolts to access the brake pads.
Check the thickness of the brake pads; replace if below manufacturer specifications.
Inspect rotors for warping or scoring; if warped (more than 0.002 inches runout), replace them.

B. Replace Brake Rotors (if necessary)

Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is seated properly against the hub.

C. Replace Brake Pads (if necessary)

Install new brake pads in the caliper bracket.
Reinstall the caliper over the new pads and torque bolts to manufacturer specifications (typically 25-35 ft-lbs).

4. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified torque (usually around 90-100 ft-lbs).
Check for proper clearance and alignment of all components.

5. Test Drive

Conduct a test drive to ensure the issue is resolved and the vehicle no longer shakes when braking.
