Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle battery to prevent any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Check thickness; replace if less than 3mm.
- Look for uneven wear patterns.
Brake Rotors:
- Inspect for grooves or scoring.
- Measure rotor thickness; replace if below minimum specification.
Calipers:
- Ensure calipers move freely and are not sticking.

4. Clean Components

Use brake cleaner to remove dust and debris from brake pads, rotors, and calipers.
Wipe down all components thoroughly.

5. Lubricate Contact Points

Apply brake lubricant to the back of the brake pads and any contact points on the calipers to prevent noise.
Avoid getting lubricant on the friction surface of the pads or rotors.

6. Reassemble and Test

Reinstall the wheel and torque lug nuts to the manufacturer’s specifications.
Lower the vehicle and reconnect the battery.
Test drive the vehicle to confirm repair success and monitor for any noises.
