Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake fluid, OBD-II scanner, multimeter, brake cleaner, safety glasses, gloves.
Lift the vehicle using a jack, secure it with jack stands, and remove the wheels using a lug wrench.

2. Inspect Brake Components

Sub-steps:
1. Examine brake pads for thickness; replace if worn down to 3mm or less.
2. Check rotors for scoring or warping; replace or resurface as necessary.
3. Inspect brake lines visually for leaks and corrosion. Replace damaged lines.
4. Check the brake calipers for proper function; ensure they are not sticking or leaking.

3. Brake Fluid and System Maintenance

Sub-steps:
1. If brake fluid is contaminated, perform a brake fluid flush using fresh DOT 3 or DOT 4 fluid as specified by the manufacturer.
2. Bleed the brake lines to remove any air bubbles from the system.
3. Ensure the master cylinder is full of fresh brake fluid and functioning properly.

4. Replace Components if Necessary

Sub-steps:
1. If brake pads are worn, replace them with high-quality aftermarket or OEM pads.
2. If rotors are warped or scored, replace them with new rotors, ensuring proper torque specifications (typically 80-100 lb-ft) upon installation.
3. Replace any faulty calipers or brake lines as necessary.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheels and lower the vehicle.
2. Pump the brake pedal several times to ensure proper pressure is built up.
3. Test drive the vehicle at low speeds to confirm that brakes function correctly.
