Ensure the vehicle is parked on a level surface and turn off the ignition.
Wear gloves and safety glasses for protection.

2. Inspect and Fill Brake Fluid

Tools Required: Brake fluid, funnel, clean rag
Instructions:
1. Locate the brake fluid reservoir, which is typically found near the back of the engine bay on the driver's side.
2. Clean the reservoir cap with a clean rag to prevent contamination.
3. Open the reservoir cap and check the fluid level against the “MIN” and “MAX” markings.
4. If fluid is low, add the appropriate type of brake fluid (usually DOT 3 or DOT 4 as specified in the owner’s manual) until it reaches the “MAX” line.
5. Replace the cap securely.

3. Check for Leaks

Tools Required: Flashlight
Instructions:
1. Inspect the brake lines from the master cylinder to each wheel for any signs of leaks or damage.
2. Look for wet spots or corrosion around the brake calipers and wheel cylinders.
3. If leaks are found, replace the damaged brake lines or components as needed.

4. Inspect the Master Cylinder

Tools Required: None
Instructions:
1. Check the master cylinder for any signs of external leakage.
2. If fluid is leaking from the master cylinder, it may need to be rebuilt or replaced.

5. Reassemble and Test

Instructions:
1. After addressing any leaks and filling the brake fluid, ensure all parts are secured.
2. Start the vehicle and pump the brake pedal to restore pressure.
3. Check that the brake fluid warning light has turned off.
