Solution

1. Preparation

Gather tools and parts before starting the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery cable for safety.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle (depending on which end is vibrating).
Secure with jack stands for safety.
Remove lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect: Check the brake rotors for warping using a dial indicator or by visually inspecting for grooves.
Replace (if warped):
- Remove the caliper by unbolting it from the bracket.
- Secure the caliper with a bungee cord to avoid stress on the brake line.
- Unscrew the rotor from the hub; if stuck, tap gently with a hammer.
- Install new rotors, ensuring they are clean and free of debris.
- Torque the rotor screws to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the condition of the caliper slides for smooth operation.
Install new brake pads, ensuring they fit correctly into the caliper bracket.
Apply brake grease to the backing of the pads to prevent noise.

5. Reassemble and Test

Reattach the caliper over the new pads and rotor.
Reinstall the wheel and lug nuts, hand-tightening initially.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
Reconnect the negative battery cable.
