Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use wheel chocks to prevent movement.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts on the wheel before lifting the vehicle.
2. Use the jack to lift the vehicle and securely place jack stands under the vehicle.
3. Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect Brake Components

Sub-steps:
1. Visually inspect brake pads for excessive wear; replace if less than 1/8 inch thick.
2. Check the rotors for any grooves or surface imperfections; measure thickness with a micrometer.
3. Ensure calipers are properly functioning and free of leaks or sticking.

4. Replace Brake Pads (if necessary)

Tools Required: Torque wrench, brake cleaner, new brake pads.
Sub-steps:
1. Remove the caliper bolts using a socket.
2. Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Clean the caliper bracket with brake cleaner and install the new pads.
5. Reinstall the caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer specifications.

5. Replace Rotors (if necessary)

Tools Required: Brake rotor replacement, torque wrench.
Sub-steps:
1. Remove the caliper and bracket as described in the previous step.
2. Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
3. Install the new rotor, ensuring it is seated properly on the hub.
4. Reattach the caliper and bracket, securing with bolts and torqueing to specifications.

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and remove the jack stands.
3. Tighten lug nuts to the manufacturer's torque specifications.
4. Pump the brake pedal to ensure proper brake pad seating before driving.
