Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the front and rear of the vehicle.
Secure with jack stands for safety.

3. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner
- Remove the wheel lug nuts and take off the wheel.
- Remove the brake caliper by unbolting it and suspend it to avoid strain on the brake line.
- Take off the brake rotor.
- Measure the rotor thickness and inspect for warping with a runout gauge.
- If warped, replace with new rotors, ensuring they meet OEM specifications.

4. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, torque wrench
- Inspect the condition of the brake pads for thickness and uneven wear.
- If worn, replace with new brake pads, ensuring they are compatible with the new rotors.
- Apply brake grease to the backing of the pads to minimize noise.

5. Reassemble and Torque

Reinstall the brake rotor and caliper.
Torque the caliper bolts to the manufacturer's specifications.
Reattach the wheel and torque the lug nuts in a crisscross pattern.

6. Test Drive

Lower the vehicle back to the ground.
Conduct a test drive to ensure the shaking is resolved.
