Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
If the brake fluid level is low, clean the area around the master cylinder cap to prevent contamination.
Open the master cylinder reservoir cap and add the recommended brake fluid type (usually DOT 4 or DOT 5.1).
Close the cap securely.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line repair kit (if necessary)
Visually inspect all brake lines for signs of leaks or damage. Pay close attention to connections and fittings.
Tighten any loose fittings. Replace any damaged or leaking brake lines using appropriate repair methods.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench for bleed screws, clear tubing
Start with the brake furthest from the master cylinder (usually the right rear).
Attach the clear tubing to the bleeder screw and submerge the other end in a container with brake fluid.
Open the bleeder screw and have an assistant press the brake pedal slowly.
Close the bleeder screw before the brake pedal is released. Repeat until clear fluid without bubbles emerges.
Move to the next brake (left rear, then right front, then left front) and repeat the process.

5. Test Brake Function

Lower the vehicle if it was raised.
Press the brake pedal several times to ensure it feels firm.
Conduct a test drive in a safe area to ensure brakes function correctly.
