Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for added safety.

2. Remove the Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspection: Check the rotors for any signs of warping or scoring.
Replacement: If rotors are warped, remove the caliper bolts and slide the caliper off the rotor.
- Tools Required: Socket set, brake caliper tool.
Install new rotors by sliding them onto the hub, ensuring they are properly seated.

4. Inspect and Replace Brake Pads

Inspection: Check the brake pads for thickness and any uneven wear.
Replacement: If pads are worn, remove them from the caliper bracket.
- Tools Required: Pliers, brake grease.
Install new brake pads, applying brake grease to the backing to prevent noise.

5. Reassemble and Torque Components

Reattach the brake caliper over the new pads and rotor.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

6. Test the Brakes

Before driving, pump the brake pedal to ensure proper engagement of the pads against the rotors.
Conduct a test drive to confirm the shaking has been resolved.
