Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Pads

Remove the Wheel:
- Use a socket set to loosen lug nuts and lift the vehicle with a jack. Secure it with jack stands.
Remove Brake Caliper:
- Unbolt the caliper using the appropriate socket. Support it with a bungee cord or similar device to avoid stressing the brake line.
Inspect Brake Pads:
- Check for uneven wear; if they are worn beyond the manufacturer’s specifications, replace them.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads and install them in the caliper bracket.

3. Inspect and Replace Brake Rotors

Check Rotor Condition:
- Measure rotor thickness using a micrometer; replace if below specification or if warped.
Remove Brake Rotor:
- Unbolt the rotor from the hub. If it’s stuck, gently tap it with a rubber mallet.
Install New Rotor:
- Place the new rotor onto the hub and secure it with bolts to the manufacturer’s torque specifications (usually around 80-100 ft-lbs).

4. Inspect Suspension Components

Check for Wear and Play:
- Visually inspect control arms, bushings, and ball joints for wear or damage.
Replace Worn Components:
- If any components are worn, follow the manufacturer’s service manual for replacement procedures.

5. Reassemble and Test

Reattach Caliper:
- Bolt the caliper back onto the rotor and ensure it’s secure.
Reinstall Wheel:
- Place the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the manufacturer’s specifications (typically 76-94 ft-lbs).
Test Drive:
- Conduct a test drive to ensure the shaking has been resolved.
