Brakes use hydraulic pressure to enable you to slow and stop your vehicle more easily. In essence, brake fluid translates kinetic energy from the pressure of your foot on the pedal into intensified pressure that is dispersed through your brake lines. When your brake fluid levels get low, there isn't as much fluid to increase your pressure, so braking is harder to do. Maintaining brake fluid levels is important for your brakes to function.
Most Common Brake Fluid Issues
You can lose hydraulic pressure in your brake lines for many reasons. The most common problems are:
- Brake fluid loss
- Air in brake lines
- Old or contaminated brake fluid
Regardless of what is going on with your fluid levels, the first step is to identify the problem and that requires a brake inspection.
Air in the Brake Lines
Over time, fluid levels will tend to drop from normal usage and brake wear. Plus, your brake system may develop cracks and leaks. When this happens, air can get in the brake lines to fill the void where the missing fluid once occupied. Even checking brake fluid levels can let air in, so it is important to keep fluid levels full.
Old or Contaminated Brake Fluid
Like motor oil and other fluids in your vehicle, brake fluid gets dirty and is rendered less effective. Additionally, brake fluid absorbs water, drawing water into the system whenever it's exposed to air during a fluid check. That moisture can eventually start damaging components in the brake system, especially metallic components that are prone to rust.
Why Is the Brake Fluid Low?
Usually this is caused by leaks in the system, but normal usage can also deplete brake fluid levels. One reason fluid loss can occur is because as your shoes or pads wear down from normal use space opens between those pads and shoes and between the rotors or drums. It takes more fluid to cross the space to reach the wheels.
How to Know If the Fluid Is Old or Contaminated
Brake fluid is usually colorless, but it can be light brown or amber. Old fluid is usually a darker brown because it can carry debris that it collected as it circulates through the lines. The debris in the fluid can begin to break down seals on the master cylinder and brake calipers.
If you don't want to rely on color, you can have the fluid tested by a certified technician who will make recommendations as to whether you should have the fluid purged and replaced.
