Solution

1. Preparation

Gather tools and parts needed for the brake inspection and repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather necessary safety equipment (gloves, goggles).

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure with jack stands.
3. Remove lug nuts completely and take off the wheel.
Tools Required: Socket set, jack, jack stands.

3. Inspect Brake Components

Sub-steps:
1. Inspect brake pads for thickness; replace if less than 3mm.
2. Check the brake rotors for grooves or uneven surfaces; measure thickness with a micrometer.
3. Ensure calipers move freely; check for any signs of leaks or damage.
Tools Required: Caliper tool, micrometer.

4. Replace Brake Pads and/or Rotors

Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts; support it without straining the brake line.
2. Remove old brake pads from the caliper bracket.
3. If necessary, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
4. Install new rotors if replacing; torque to manufacturer's specifications (typically 80-100 ft-lbs).
5. Install new brake pads in the caliper bracket.
6. Reattach the caliper and tighten bolts to manufacturer specifications (usually 30-40 ft-lbs).
Tools Required: Torque wrench, socket set, brake cleaner, new brake pads, new rotors.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten lug nuts.
2. Lower the vehicle and torque lug nuts to specifications (typically 80-100 ft-lbs).
3. Pump the brake pedal to seat the pads against the rotors.
4. Test drive at low speeds to ensure proper brake function and check for noises.
Tools Required: Torque wrench.
