Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use a jack and jack stands to safely lift the vehicle.

2. Remove Wheel

Loosen lug nuts with a socket set before lifting the vehicle.
Use a jack to raise the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Use a dial indicator to measure rotor thickness and check for warping.
Replace Rotors:
- If warped, remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off and support it with a wire or bungee cord to avoid stressing the brake line.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, reversing the removal steps, ensuring it is seated properly.

4. Check and Replace Brake Pads

Inspect Pads: Check the thickness of the pads; if they are worn below 3 mm, they need replacement.
Replace Pads:
- Remove the old pads from the caliper bracket.
- Compress the caliper piston using a brake caliper tool.
- Install new pads in the caliper bracket.

5. Reassemble and Test

Reattach the caliper over the new pads and secure it with caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Test drive the vehicle to ensure vibrations are eliminated.
