Why does my car lose brake fluid?

Do you suspect your vehicle may have a brake fluid leak in the braking system? Is the level of brake fluid a little low? The explanation for this low level of liquid is quite simple: If your car already have some years and have never done a brake maintenance, chances are you wear, the level has gone down and you have to take it to a workshop to do the review have not done in recent years. But say you have a relatively new brakes and recently you checked the brake fluid level to verify that only one month after the level has dropped an important way. In this case, chances are you have a leak in the braking system - which means you have a different problem to a simple worn brakes.


The braking system we use in our cars is made up of a number of elements and metal rubber hoses, valves, pistons and cylinders. All come together and work in harmony to brake and stop the car. It can help you understand it better if you imagine your braking system and cardiovascular system, pumping blood to different areas of the body. The master cylinder vehicle and acts as the heart pumps the brake fluid through the lines to the extremities, in this case the brake drums and caliper (brake calipers). This is where many problems originate brakes. In the four corners of our car, the brake lines - connections that connect the master cylinder to the different parts of the braking system that makes brake or stop the wheels - can simply leak.

In fact, anywhere within the braking system that connects the other hand, has the potential to become another point of leakage. All these parts can wear out or may have perforations, or may even be torn in an accident or any other circumstance (a simple stone hitting the low road). Braking circuits pass through different parts of the car, and in some systems, the brake fluid valves pass under the engine, and which can cause a leak somewhere near the master cylinder.

Bleed valves, also known as bleed valves are located in brake calipers and are designed to allow the brake fluid to flow out of the system. If you have recently had some work on the brakes of your car, it could be that one of the bleed valves are inadvertently left something loose. If that's the case, it is a simple fact tighten the valve to stop fluid flow. It could also be that the problem includes a characteristic symptom in the brake pedal, where we notice looser than usual. If you experience that the brake pedal goes straight to the floor with little or no resistance, you can try to quickly pump the pedal (step on it and drop it in sequence) to recover pressure. If you are unable to recover pressure after several attempts, you could have a number of brake fluid leakage.

It is possible that some of the brake lines which is perforated or some of the seals have failed. Both cases are easily solved, but should be done as soon as possible - your safety and the safety of the occupants of the car depends on it. You have to remember something, the brake fluid is vital for the system to operate properly brake. The release system leaks fluid, causing a reduction in the brake pressure (or even complete disappearance). If nothing is done about it, your car will eventually run out this fluid. However, chances are it will not come to that point because the brakes stop working after fluid levels have dropped to a certain level.
