Solution

1. Preparation

Tools Required:
- Socket set
- Brake bleeder kit
- Wrench set
- Brake fluid (DOT 3 or DOT 4, as specified in the owner’s manual)
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the appropriate brake fluid until the correct level is reached.
Replace the cap securely.

3. Inspect for Leaks

Visually inspect brake lines, connections, and components for signs of fluid leaks.
Look under the vehicle for any pooled brake fluid.
If leaks are found, replace the damaged lines, seals, or components as necessary.

4. Bleed Brake System

Tools Required: Brake bleeder kit, clear tubing.
Connect the tubing to the brake bleeder valve on the caliper and place the other end in a container.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow air and fluid to escape, then close it before your assistant releases the pedal.
Repeat this process until no air bubbles are visible in the fluid.
Ensure all four wheels are bled.

5. Test Brake Booster

With the engine off, pump the brake pedal several times to remove any residual vacuum.
Then, press the brake pedal and start the engine; the pedal should drop slightly if the brake booster is functioning properly.
If it doesn't drop, the brake booster may need replacement.
