Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Pads: Measure the thickness of the brake pads. If they are below 3mm, replace them.
Remove Old Pads: Remove the caliper bolts using a socket wrench. Carefully slide the caliper off the rotor.
Replace Pads: Remove the old brake pads from the caliper bracket and replace them with new ones. Ensure they are properly seated.
Reattach Caliper: Slide the caliper back onto the rotor and secure it with the caliper bolts. Torque the bolts to the manufacturer's specifications (typically around 30-40 Nm).

4. Inspect and Replace Brake Rotors (if needed)

Check Rotors: If the rotors are damaged or worn beyond specifications (usually more than 0.5mm of wear), replace them.
Remove Rotors: Remove the rotor by unscrewing any retaining screws and sliding it off the wheel hub.
Install New Rotors: Position the new rotor onto the hub and secure it with retaining screws (if applicable).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically around 90-100 Nm).
Repeat the brake test to ensure the brakes are functioning correctly without noise.
