Solution

1. Preparation

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

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads and rotors.
If brake pads are worn:
- Remove the caliper bolts using a socket.
- Carefully slide the caliper off the rotor without disconnecting the brake line.
- Remove the old brake pads from the caliper bracket.

4. Replace Brake Pads

Install new brake pads into the caliper bracket.
If rotors are damaged:
- Remove the rotor by unscrewing the retaining screws and pulling it off the hub.
- Install new rotors, ensuring they are properly seated.

5. Reassemble Braking System

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specification (typically around 25-35 Nm).
Reattach the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Pump the brake pedal several times to ensure proper seating of the pads and caliper.
