Solution

1. Preparation

Gather tools and parts required for brake inspection and repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and OBD-II scanner.

2. Inspect and Replace Brake Pads

Remove Wheel:
- Loosen lug nuts with the lug wrench.
- Raise the vehicle using a jack and securely support it with jack stands.
- Fully remove the lug nuts and take off the wheel.
Inspect Brake Pads:
- Check brake pad thickness; replace if below manufacturer specifications.
- Look for signs of uneven wear or glazing.
Replace Brake Pads:
- Remove caliper bolts using a socket set.
- Slide the caliper off the rotor and support it (do not let it dangle from the brake line).
- Remove old brake pads and install new pads, ensuring they are oriented correctly.
- Reattach the caliper over the new pads and tighten caliper bolts to manufacturer torque specifications, typically around 20-30 ft-lbs.

3. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotors:
- If rotors are warped or damaged, remove them by unscrewing the rotor retaining screws if applicable.
- If stuck, gently tap with a rubber mallet.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective oil.
- Install the new rotors onto the hub and secure them with retaining screws.
Reinstall Wheel:
- Reattach the wheel and hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to manufacturer specifications, usually around 80-100 ft-lbs.
