Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Lift the Vehicle

Use a hydraulic jack to raise the front of the vehicle and secure it on jack stands.
Remove the front wheels using a lug wrench.

3. Remove Brake Components

Brake Caliper Removal:
- Use a socket set to remove the caliper mounting bolts.
- Carefully lift the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Brake Pad Removal:
- Remove the old brake pads by sliding them out of the caliper bracket.
Brake Rotor Removal:
- If necessary, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.

4. Inspect and Clean Components

Clean the brake rotor surface with brake cleaner to remove any residue.
Inspect the caliper for any leaks or damage; replace if necessary.
Check the brake pads for wear; replace if less than 3mm thick.

5. Install New Components

New Brake Pads:
- Apply a thin layer of brake grease to the backing of the new pads to prevent noise.
- Slide the new brake pads into the caliper bracket.
New Brake Rotor (if applicable):
- Install the new rotor onto the hub, securing it with the retaining screws.
Reinstall Brake Caliper:
- Position the caliper over the new pads and rotor.
- Tighten the caliper mounting bolts to the manufacturer’s specified torque (typically 30-35 Nm).

6. Reassemble and Lower Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the hydraulic jack.
Torque the lug nuts to the manufacturer’s specifications (typically 120-140 Nm).
