Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if electrical components will be handled.

2. Wheel Removal

Use a socket set to loosen and remove the lug nuts.
Safely lift the vehicle using a jack and secure it on jack stands.
Remove the wheels to access the brake components.

3. Brake Pad Inspection and Replacement

Inspect Brake Pads:
- Measure the thickness of the pads; if less than 3mm, replace them.
Remove Brake Caliper:
- Use a socket to remove caliper mounting bolts.
- Carefully slide the caliper off the rotor.
Remove Old Brake Pads:
- Slide the old pads out of the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads and contact points.
- Slide the new pads into the caliper bracket.

4. Brake Rotor Inspection and Replacement

Inspect Rotors:
- Check for grooves or warping using a micrometer.
Remove Old Rotor:
- Remove any retaining screws and slide the rotor off the hub.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Slide the new rotor onto the hub and secure it with screws if applicable.

5. Reassemble and Test Brakes

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (typically around 25-30 Nm).
Reinstall the wheels and torque the lug nuts to the manufacturer's specification (typically around 120 Nm).
Lower the vehicle and reconnect the battery.
