Solution

1. Preparation

Gather tools: socket set, torque wrench, dial indicator, caliper gauge, brake cleaner, and a jack.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Remove Wheel

Loosen the lug nuts slightly while the wheel is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Slide the caliper off the rotor and inspect the brake pads for thickness. Replace if they are below the manufacturer’s specifications.
Brake Rotors:
- Check the rotor surface for warping using a dial indicator. If warped beyond specifications, replace the rotor.
- Clean the rotor surface with brake cleaner and a clean cloth.

4. Reassemble

Reinstall the caliper over the new or inspected pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value in a crisscross pattern.

5. Test Brake System

Press the brake pedal several times to ensure proper seating of the pads.
Perform a test drive to confirm the shaking issue is resolved.
