Solution

1. Preparation

Gather tools and safety equipment, including gloves and safety glasses.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels using a socket set.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts and slide the caliper off the rotor.
- Inspect the brake pads for thickness; replace if less than 3mm.
Brake Rotors:
- Check the rotor surface for deep grooves or scoring.
- If damaged, replace the rotors.

4. Replace Brake Pads and Rotors (if necessary)

Removing Old Pads:
- Unclip the old brake pads from the caliper bracket.
Installing New Pads:
- Apply brake grease to the backing of the new pads to prevent noise.
- Clip the new pads into place.
Replacing Rotors:
- Remove the old rotor by unscrewing the retaining screws (if applicable).
- Install the new rotor and secure it with screws.

5. Reassemble Braking System

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque (usually between 20-30 ft-lbs).
Repeat for the other side if necessary.

6. Final Checks

Reinstall the wheels and lower the vehicle.
Pump the brake pedal several times to seat the brake pads.
