Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and securely lifted with jack stands.

2. Inspect and Replace Brake Rotors

Remove the Wheel:
- Use a lug wrench to loosen lug nuts, then lift the vehicle with a jack.
- Remove the lug nuts and take off the wheel.
Check Brake Rotors:
- Use a runout gauge to measure rotor runout; excessive runout indicates warping.
- If warped, proceed to replace the rotors.
Remove Brake Caliper:
- Unbolt the caliper using a socket set and hang it securely (do not let it dangle by the brake line).
- Remove the brake pads from their housing.
Replace Rotors:
- Unbolt the rotor from the hub assembly; clean the hub surface.
- Install new rotors, ensuring they are seated properly.

3. Replace Brake Pads

Install New Brake Pads:
- Insert new pads into the caliper bracket.
- Ensure anti-squeal shims (if present) are installed correctly.
Reinstall Brake Caliper:
- Position the caliper over the new pads and bolt it back onto the caliper bracket.
- Torque bolts to manufacturer specifications.

4. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the specified value.

5. Test the Brakes

Pump the brake pedal to seat the pads.
Test drive the vehicle to ensure the shaking has been resolved.
