Solution

1. Preparation

Gather necessary tools and materials.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

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:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for wear; replace if less than 3mm thick.
Brake Rotors:
- Check for grooves or scoring; if warped, replace the rotor.
- Clean the surface of the rotor with brake cleaner.

4. Replace Brake Pads

If needed, compress the caliper piston using a brake caliper tool.
Install new brake pads, ensuring they are correctly aligned.
Reattach the caliper and secure it with bolts; torque to manufacturer specifications (typically 25-35 ft-lbs).

5. Reassemble and Test

Reattach the wheel and tighten lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
Lower the vehicle and remove jack stands.
Pump the brake pedal to ensure proper engagement before driving.
