Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to raise the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and inspect the brake pads for thickness; replace if below 3mm.
Brake Rotors:
- Check for surface scoring or warping; if damaged, replace the rotor.

4. Clean and Lubricate

Use brake cleaner to remove dust and debris from the brake pads and rotors.
Apply anti-squeal lubricant to the backside of the brake pads to reduce noise.

5. Reassemble the Brake System

Reinstall the brake caliper over the new or inspected pads.
Tighten the caliper bolts to the manufacturer’s specifications (usually around 25-30 Nm).
Reinstall the wheel and lower the vehicle.
