Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues while working on the brake system.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the affected wheel slightly while the vehicle is on the ground.
2. Raise the vehicle using a hydraulic jack and secure it with jack stands.
3. Fully remove the lug nuts and take off the wheel.
Tools Required: Lug wrench, hydraulic jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by unscrewing the caliper bolts with a socket wrench.
2. Slide the caliper off the rotor and suspend it securely (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Compare new pads to old ones to ensure proper fit.
5. Install new brake pads into the caliper bracket.
6. Reattach the caliper over the new brake pads and tighten the caliper bolts to the manufacturer's torque specification (typically 25-35 ft-lbs).
Tools Required: Socket wrench, torque wrench.

4. Inspect and Resurface or Replace Rotors

Sub-steps:
1. If the rotors are scored, remove them by unscrewing the rotor screws (if applicable) and pulling the rotor off the hub.
2. Evaluate the rotor thickness; if below the minimum specification, replace the rotor.
3. If resurfacing, take rotors to a machine shop to ensure a smooth surface.
4. Reinstall the rotor if resurfaced or replace it with a new rotor, ensuring proper alignment.
Tools Required: Socket wrench, rotor removal tool (if necessary).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer's torque specification (typically 85-100 ft-lbs).
3. Reconnect the battery.
4. Pump the brake pedal a few times to seat the brake pads.
Tools Required: Torque wrench.
