Solution

1. Preparation

Gather necessary tools and park the vehicle on a flat, stable surface.
Ensure the vehicle is in "Park" or "Neutral" with the parking brake engaged.
Tools Required: Jack, jack stands, wheel chocks, brake cleaner, OBD-II scanner.

2. Brake Fluid Check

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the "MIN" and "MAX" indicators.
If low, add the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).

3. Brake Pad and Rotor Inspection

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel to access the brake components.
Inspect the brake pads for thickness; replace if below 3mm.
Check the rotors for scoring or warping; replace if necessary.

4. Brake Line and Caliper Inspection

Inspect brake lines for leaks or cracks; replace any damaged sections.
Examine calipers for fluid leaks; if leaking, they must be replaced.
Ensure all connections are tight and in good condition.

5. Bleed the Brake System (if applicable)

If air is suspected in the brake lines, bleed the brake system:
1. Start with the caliper furthest from the master cylinder.
2. Attach a clear hose to the bleeder valve and submerge the other end in a container of brake fluid.
3. Open the bleeder valve while an assistant presses the brake pedal.
4. Close the valve before releasing the pedal and repeat until no air bubbles are present.

6. Reassembly

Reinstall the wheel and lower the vehicle.
Tighten lug nuts to the manufacturer's specified torque.
Dispose of any old brake fluid and parts in accordance with local regulations.
