Why Do I Need to Change My Brake Fluid?

The brake system is arguably the most important aspect of vehicle safety, but many people wonder if changing brake fluid periodically is necessary. Brakes are a hydraulic system and require brake fluid to operate. Working under extremely high temperatures the brake pressure pushes fluid down to your brakes when the pedal is pressed. This force is applied to each of the brake rotors, effectively applying pressure to the wheels to slow the movement of the vehicle. However, brake fluid does absorb moisture and degrade over time, so regular brake fluid flushing is highly recommended.

Do I Need a Brake Fluid Flush?

It is necessary to drain and replace brake fluid periodically because it absorbs moisture from the air and degrades over time. Changing brake fluid at recommended intervals will allow the brake system to operate safely and efficiently. Brake fluid changes are typically done every one or two years, you should follow OEM recommendations.

  • The braking process generates heat, which breaks down and wears away at your brake fluid.
  • This process leaves moisture behind, which can cause your brakes to rust.
  • Particles of debris, rubber, and metal can contaminate the solution over time.

The above issues can lead to reduced brake performance and, possibly brake failure if left unattended.

Which Brake Fluid is right for me?

DOT 5.1 has very wide applicability and can be used with confidence in any brake system where the use of glycol ether fluid is specified. This includes the latest generation full electric and electric hybrid vehicles where low conductivity is essential, as well as high performance European vehicles. It is fully compatible with and can replace or top up systems using DOT 4 and DOT 3 fluids. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid. DOT 5 is used mostly in classic cars that remain in storage for long periods and need a brake fluid that does not absorb water.
