Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Pads

Remove the wheel using a socket set.
Inspect brake pads for wear; replace if they are below the manufacturer's minimum thickness.
If replacing, slide the new brake pads into place, ensuring they fit snugly against the rotor.
Reassemble the wheel and torque to manufacturer specifications (usually around 100-130 lb-ft).

3. Inspect and Resurface or Replace Brake Rotors

Check the rotors for warping using a dial indicator or straight edge.
If warped, resurface the rotors according to specifications or replace them if beyond repair.
Install new or resurfaced rotors, ensuring they are properly seated.

4. Check and Replace Brake Calipers (if necessary)

Inspect brake calipers for leaks or sticking pistons.
If faulty, remove the caliper by unbolting it from the bracket.
Replace with a new caliper and bleed the brake lines to remove air.

5. Examine Suspension Components

Inspect control arms, bushings, and tie rods for wear or damage.
Replace any worn components to ensure proper alignment and handling.

6. Wheel Balance and Alignment

Have the wheels balanced and aligned by a professional to ensure optimal performance and prevent future shaking.
