Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to ensure safety while working on the brake system.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Loosen the lug nuts on the front wheels and raise the vehicle using a jack, then secure with jack stands.
2. Remove the front wheels using the lug wrench.
3. Inspect the brake pads for thickness; replace if below 3mm.
4. If replacement is necessary, remove the caliper bolts and slide the caliper off the rotor.
5. Remove old pads and install new brake pads, applying brake grease to the backing plates.
6. Reattach the caliper and torque bolts to the manufacturer’s specifications.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. If rotors are warped, remove the caliper and pads as described previously.
2. Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
3. Measure the rotor thickness with a micrometer; replace if below minimum specifications or if warped.
4. Install new rotors, ensuring they are clean and free from grease.
5. Reinstall the caliper and pads as previously described.

4. Brake Fluid Inspection and Replacement

Sub-steps:
1. Locate the brake fluid reservoir and check the fluid level.
2. If the fluid is dark or contaminated, drain and replace it.
3. Use a brake bleeder kit to flush the old fluid from the brake lines and refill with new brake fluid as per the manufacturer's specifications.
4. Bleed the brakes starting from the furthest wheel to the closest.
