Solution

1. Preparation

Tools Required: OBD-II scanner, brake pad gauge, torque wrench, jack and jack stands, brake cleaner.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear appropriate safety gear, including gloves and safety glasses.

2. Brake Pad Replacement

Sub-steps:
1. Loosen the lug nuts on the wheel where brake pads are to be replaced.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheel to access the brake assembly.
4. Remove the caliper bolts and carefully slide the caliper off the rotor.
5. Remove the old brake pads from the caliper bracket.
6. Install new brake pads into the caliper bracket.
7. Reposition the caliper over the new pads and secure it with caliper bolts, torqueing to manufacturer specifications.

3. Rotor Replacement (if needed)

Sub-steps:
1. If the rotors are damaged, remove them by unscrewing the rotor retaining screws.
2. Install new rotors, ensuring they are clean and free of grease.
3. Secure the rotors with retaining screws.

4. Brake Fluid Replacement

Sub-steps:
1. Locate the brake fluid reservoir and remove the cap.
2. Use a brake bleeder kit to remove old brake fluid from the system.
3. Refill the reservoir with new brake fluid as specified in the owner's manual.
4. Bleed the brake system using the proper sequence to remove air bubbles.
