What Does Brake Fluid Do?


A Brief Introduction to Brake Fluid

The brakes are probably your vehicle’s most important system. Most of us can tell when our brakes need attention. Either they don’t slow you down, or they make strange noises. But do you know what brake fluid is all about, or when and if you need to change it? Here are a few things you may not know about your vehicle’s braking system–what brake fluid does, what the brake light means, and why brakes leak.

What Does Brake Fluid Do?

Brake fluid is used to help move different parts of your braking system. Whenever you press the brake pedal, brake fluid is released from the master cylinder to the brake lines. The brake fluid reaches the calipers, allowing the various braking system parts to engage and bring the vehicle to a stop.

What Does the Dashboard Brake Light Mean?

The dashboard’s brake lights can be triggered by the emergency brake being on. It’s possible to start driving with the emergency brake still on, depending on the condition of the emergency brakes. This mistake is easy to fix, but if you release the emergency brake and the light is still on, it could be caused by a couple of reasons. There could be a problem with the brake hydraulic system, or the level of brake fluid could be too low.

Why Does Brake Fluid Leak?

That slimy yellowish or brownish liquid under your car is brake fluid. At this point, you might even notice that the brakes’ responsiveness has been compromised, or it feels soft like a sponge when you press the pedal. Like any other vehicle component, brake lines are susceptible to wear, tear, and corrosion. Damage to any brake system parts, such as brake pads, brake switches, pistons, lines, and cylinders can cause brake fluid to leak.
