Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.
Disconnect the negative terminal of the battery to avoid any electrical issues.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Sub-steps:
1. Loosen the lug nuts on the wheel with a socket wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the caliper mounting bolts and remove them using a socket.
2. Carefully slide the caliper off the rotor and support it (do not let it hang by the brake line).
3. Remove the brake pads from the caliper bracket.

4. Inspect and Replace Components

Tools Required: Micrometer, brake cleaner, wire brush (if needed)
Sub-steps:
1. Inspect the brake pads for wear; replace them if they are below the minimum thickness.
2. Check the rotors for damage; if worn or scored, replace them.
3. Clean the rotor surface with brake cleaner and a wire brush to remove any debris.
4. If necessary, resurface the rotors following manufacturer's specifications.

5. Reassemble the Brake System

Tools Required: Torque wrench
Sub-steps:
1. Install new brake pads into the caliper bracket.
2. Reposition the caliper over the rotor and pads.
3. Tighten the caliper mounting bolts to the manufacturer's torque specifications.
4. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Tools Required: Torque wrench
Sub-steps:
1. Lower the vehicle from the jack stands.
2. Tighten the lug nuts to the specified torque in a crisscross pattern.
3. Reconnect the negative battery terminal.
