What is Brake Fluid?

Brake fluid is a hydraulic fluid that helps with your brake pedal’s movement. It will also lubricate the braking system to keep it from corroding. In most vehicles, brake fluid is glycol-ether based, but there are also silicone-based (DOT-5) and mineral oil-based (LHM) fluids available. Refer to your vehicle’s owner’s manual to know which type your car uses.

3 Steps to Check Brake Fluid

  1. Locate your vehicle’s brake fluid reservoir on the master cylinder that’s under the hood. Refer to your vehicle’s owner’s manual to find the exact location.
  2. On the outside of the reservoir, you should see “minimum” and “maximum” lines. Check the brake fluid against these lines. If the brake fluid is closer to the minimum line, it’s time for a brake fluid replacement or brake service.
  3. Take a look at the color of the brake fluid. If it’s dark brown or black and looks more like oil, a brake fluid flush is needed.

Why Does Brake Fluid Need to Be Changed?

Wondering if brake fluid needs to be changed? Yes, it does! And for the following reasons:

  • Brake fluid attracts moisture, which over time, causes corrosion on your brakes.
  • When brake fluid ages, it becomes contaminated with small particles that damage brake-related systems. Systems like ABS and traction control generate heat when they activate, which shortens the lifespan of the brake fluid.

You’ll want to regularly check the brake fluid to avoid a situation where your brakes fail to stop due to the damage.

What Color is Brake Fluid Normally?

Brake fluid that’s new is almost clear with a slight yellow tint to it. This changes over time as you’re using the braking system. If the fluid becomes dark, it’s because it picks up debris and dirt, which affects the vehicle’s performance.

What Are the Brake Fluid Service Intervals?

The brake fluid should be checked during every oil change – or at least once a year. Brake fluid can last about four to five years but will vary depending on the car you have, your driving habits, and your driving condition. Visit our West Chester service center for routine scheduled maintenance, and our factory-trained and certified technicians can inspect and change your brake fluid.
