Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Wheel Removal

Loosen the lug nuts on the front wheels using a socket set.
Lift the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the front wheels.

3. Brake Pad and Rotor Inspection

Inspect the brake pads for sufficient material; replace if worn below specifications (usually 3mm).
Check brake rotors for warping with a dial indicator; if warped beyond specifications (usually 0.02 inches), replace.
Clean the rotor surface with brake cleaner if reinstalling.

4. Brake Pad Replacement (if necessary)

Remove the caliper bolts using a socket wrench and lift the caliper away from the rotor.
Remove the old brake pads and compress the caliper piston using a caliper tool.
Install new brake pads ensuring proper orientation.
Reattach the caliper and torque the caliper bolts to manufacturer specifications (typically around 25-30 Nm).

5. Reassembly

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer’s specifications (usually around 120 Nm).

6. Test Drive

Carefully test the brakes at low speed to ensure proper function and feel.
Monitor for any further vibrations or noises.
