Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Rotors

Lift the Vehicle:
- Use a hydraulic jack to raise the front or rear of the vehicle, depending on where the brake vibrations occur.
- Secure with jack stands.
Remove Wheel:
- Use a lug wrench to remove the lug nuts and take off the wheel.
Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully hang the caliper using a bungee cord to avoid straining the brake line.
Remove Brake Rotor:
- If necessary, remove the caliper bracket.
- Pull off the rotor; if it is stuck, tap it gently with a rubber mallet.
Install New Rotor:
- Clean the hub surface to ensure proper contact.
- Place the new rotor onto the hub.

3. Replace Brake Pads

Inspect Brake Pads:
- Check the thickness and condition of the brake pads.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads.
- Position the pads into the caliper bracket.
Reattach Caliper:
- Reinstall the caliper over the brake pads and securely tighten the caliper bolts.

4. Reassemble and Test

Reinstall Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
Lower Vehicle:
- Remove jack stands and lower the vehicle to the ground.
Tighten Lug Nuts:
- Use a torque wrench to tighten the lug nuts to manufacturer specifications (usually around 100-120 ft-lbs).
Reconnect Battery:
- Reconnect the battery terminals.
