Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear (depending on which brakes are shaking) of the vehicle.
Secure the vehicle with jack stands.

3. Inspect and Replace Brake Components

A. Inspect Rotors

Remove the wheel using a socket set.
Check rotors for warping using a run-out gauge. Replace if warping exceeds specifications.

B. Replace Rotors (if necessary)

Remove the caliper by unscrewing the caliper bolts using a torque wrench.
Suspend the caliper with a wire, avoiding strain on the brake line.
Remove the old rotor and install the new rotor, ensuring it is seated properly.

C. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new pads and install them.
Reassemble the caliper over the new pads and torque the caliper bolts to manufacturer specifications.

4. Check Suspension Components

Inspect control arms, bushings, and tie rods for wear.
Replace any worn or damaged components.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and torque lug nuts to specification.
Lower the vehicle from the jack stands and remove the jack.
