Solution

1. Preparation

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

2. Wheel Removal

Tools Required: Jack, jack stands, lug wrench.
- 1. Loosen the lug nuts on the wheel to be serviced.
- 1. Raise the vehicle using a jack and securely place jack stands underneath.
- 1. Remove the lug nuts completely and take off the wheel.

3. Brake Pad and Rotor Inspection

Tools Required: Torque wrench, caliper tool.
- 1. Remove the caliper bolts using a socket and ratchet.
- 1. Gently slide the caliper off the rotor and secure it without stressing the brake line.
- 1. Inspect the brake pads. Replace if worn down to 3mm or less.
- 1. Measure the rotor thickness with a micrometer. Replace if below the manufacturer's minimum specification.

4. Component Replacement

Tools Required: Brake pad replacement kit, rotor replacement kit (if necessary).
- 1. If replacing brake pads, remove old pads from the caliper bracket.
- 1. Install new brake pads, applying brake grease to the backing plates if recommended.
- 1. If necessary, replace the rotor by unbolting from the hub.
- 1. Install new rotor, ensuring it is properly seated.

5. Reassembly

Tools Required: Torque wrench.
- 1. Reinstall the caliper over the new pads and rotor.
- 1. Torque caliper bolts to the manufacturer's specifications.
- 1. Reinstall the wheel and hand-tighten the lug nuts.
- 1. Lower the vehicle and torque the lug nuts to the specified value.

6. Brake System Bleeding (if necessary)

Tools Required: Brake bleeder kit.
- 1. If brake fluid was lost, bleed the brake system starting from the wheel farthest from the master cylinder.
- 1. Ensure all air is removed from the brake lines.
