Brake-ing bad? Check what’s wrong!

Have you ever experienced the lack of braking power, even though your brake pads look perfectly fine? Then you know what we’re talking about. This phenomenon is widely known as ‘spongy brakes’, and it is generally caused by gas inside the hydraulic system.

What is this ‘Hydraulic system’?

The term ‘hydraulic system’ refers to a mechanism that uses some sort of fluid to transfer force. In braking systems, a special brake fluid is used to generate pressure, which is then transferred on to the brake shoes in the tires.

Why does the pressure not build up sometimes?

As we explained before, the force to stop the vehicle is built by the pressure transferred by the hydraulic liquid. If any kind of air or other gas gets stuck inside those lines, then they compress instead of the liquid when you hit the brakes without effectively transferring force. This results in a spongy feel.

Why does this happen?

Water contamination is the most common reason. As you know, brake systems get heated up – and this heat is enough to evaporate water that seeps in, turning it into steam – which in turn results in the sponginess.

Old brake fluid can be another reason. It loses its integrity over time and can get vaporized, leading to the ineffective braking.

What can we do about it?

Changing the brake fluid should be your first step. If the problem persists, then something else is causing the problem – and you must get your car checked from a trustworthy mechanic ASAP.
