Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electronic components.

2. Remove Wheel

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

3. Inspect Brake Components

Sub-steps:
1. Remove the brake caliper by unbolting it from the bracket.
2. Slide the caliper off the rotor and hang it with a bungee cord (do not let it dangle by the brake line).
3. Remove the brake pads and inspect them for wear; replace if worn down to the backing.
4. Examine the brake rotor for any grooves or damage; resurface or replace if necessary.
Tools Required: Socket set, bungee cord.

4. Replace Brake Parts (if necessary)

Sub-steps:
1. If pads are worn, install new brake pads ensuring they are seated properly.
2. If rotors are damaged, remove the old rotor and install a new one, tightening bolts to the manufacturer’s specifications (typically around 75-95 ft-lbs).
3. Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
Parts Required: Brake pads, brake rotors (if needed).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Tighten the lug nuts to the manufacturer’s specifications (typically around 76-86 ft-lbs).
