Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

Tools Required:

Socket set
Torque wrench
Brake pad spreader
OBD-II scanner

2. Inspect and Replace Brake Pads

Remove Wheel:
- Loosen lug nuts while the vehicle is on the ground.
- Lift the vehicle with a jack and secure it with jack stands.
- Fully remove the lug nuts and take off the wheel.
Inspect Brake Pads:
- Check the thickness of the brake pads; if they are below the minimum thickness, replace them.
- Look for uneven wear patterns.
Replace Brake Pads:
- Use a brake pad spreader to retract the caliper piston.
- Remove the caliper bolts and take off the caliper.
- Replace the old pads with new ones, ensuring they are seated correctly.

3. Inspect and Replace Brake Rotors

Check Rotors:
- Inspect rotors for warpage using a dial indicator.
- If warpage exceeds manufacturer specifications, replace the rotors.
Remove and Replace Rotors:
- Remove caliper brackets if necessary.
- Unbolt and take off the old rotor.
- Install new rotor and torque bolts to manufacturer specifications.

4. Reassemble and Test

Reinstall Caliper:
- Reattach the caliper over the new pads and torque bolts to specification.
Reattach Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and tighten the lug nuts to the specified torque.

5. Final Check

Reconnect the battery.
Start the vehicle and perform a test drive to ensure the vibrations are resolved.
