Solution

1. Preparation

Tools Required: Basic hand tool set, brake fluid, OBD-II scanner, multimeter (if checking electronic components).
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Allow the vehicle to cool down before starting.

2. Brake Fluid Inspection

Sub-steps:
1. Open the hood and locate the master cylinder.
2. Remove the cap and check the brake fluid level. If low, add the manufacturer-recommended brake fluid.
3. Inspect the fluid for contamination or discoloration. If dirty, consider a brake fluid flush.

3. Brake Pad and Rotor Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Visually inspect brake pads for thickness; replace if below 3mm.
4. Check rotors for grooves or warping. Measure rotor thickness with a micrometer; replace if below minimum specifications.
5. Clean the caliper and rotor surfaces using brake cleaner.

4. Brake Line Inspection

Sub-steps:
1. Examine brake lines for any signs of leaks or damage.
2. If leaks are found, replace the affected brake line or component.
3. Ensure all connections are tight and secure.

5. Brake Booster Test

Sub-steps:
1. With the engine off, press the brake pedal several times to deplete any vacuum in the booster.
2. Start the engine while holding the brake pedal down; the pedal should sink slightly.
3. If there is no change, the brake booster may need replacement.
