Diagnostic Steps

2
Check for visible leaks around the brake lines, calipers, and master cylinder.
3

Solution

1. Preparation

Tools Required: Clean rags, funnel, brake fluid (DOT 3 or DOT 4), brake fluid tester.
Ensure the vehicle is parked on a level surface and the engine is off.
Put on safety gloves and eyewear.

2. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Clean the area around the reservoir cap to prevent contamination.
Remove the reservoir cap carefully.
Check the fluid level against the minimum and maximum markings on the side of the reservoir.
If low, use a funnel to add the appropriate brake fluid (DOT 3 or DOT 4) until it reaches the maximum level.
Replace the reservoir cap securely.

3. Inspect for Leaks

Visually inspect the brake lines, calipers, and master cylinder for signs of fluid leaks.
If any leaks are found, mark the locations for repair or replacement.
Check brake pads and rotors for wear; replace if necessary.

4. Bleed the Brake System (if applicable)

If air is suspected in the brake lines, bleed the brake system:
- Start with the wheel farthest from the master cylinder (typically the rear passenger side).
- Using a brake bleeder kit, attach the hose to the bleeder valve on the brake caliper.
- Have an assistant pump the brake pedal several times and hold.
- Open the bleeder valve to allow fluid and air to escape, then close it before the assistant releases the pedal.
- Repeat until no air bubbles are seen, then move to the next wheel (rear driver side, front passenger side, front driver side).
