Right now you have stated that you pump the brake pedal to brake and this is an indication that you dont have a big leak, of course in the future it will become worse.

To properly diagnose a brake leak, you must first locate the leaking point. The best way to do this is by parking your vehicle on a level surface for a couple of hours, then observing the position of the brake fluid that has accumulated beneath the vehicle.

This will give you an idea as to which fitting may be the culprit. If you find that the puddle of brake fluid is beneath the rear of the engine, not near one of the wheels, you may have a leak somewhere in or near the master cylinder.

Bleeder bolts, sometimes called bleeder valves, are located on the brake calipers and are designed to allow brake fluid to flow out of the system. If you've recently had some brake work done on your vehicle, it may be that one of your bleeder valves was inadvertently left a little loose. If that's the case, it's a simple matter of tightening the valve to stop the fluid flow.
