Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a socket set to loosen and remove the wheel lug nuts.
Lift the wheel off and set it aside.

3. Inspect Brake Components

Examine brake pads for uneven wear; replace if necessary.
Check the brake rotors for warping using a dial indicator.
- If warped, proceed to replace the rotors.

4. Replace Brake Rotors (if necessary)

Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor and support it without stretching the brake line.
Remove the rotor by unscrewing any retaining screws or clips.
Install the new rotor, ensuring it is seated correctly.
Reassemble the caliper over the new rotor and tighten bolts to manufacturer specifications (typically around 25-35 Nm).

5. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake tool or C-clamp.
Install new brake pads, ensuring they are positioned correctly within the caliper bracket.

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications (typically around 120 Nm).

7. Test Drive

Conduct a test drive to ensure the issue is resolved, monitoring for vibrations while braking.
