Brake Fluid Replacement

Brake fluid replacement is required as part of good routine vehicle maintenance. Brake fluid is hygroscopic, meaning it has a tendency to absorb moisture. Over time, the absorbed water lowers the boiling point of the brake fluid in the brake pistons, reducing performance under hard braking.

In addition to reduced braking efficiency, brake fluid moisture content causes corrosion – particularly the pistons – but generally throughout the brake system.

How Does Moisture Get Into The Braking System?

Moisture can enter brake fluid in a number of ways.

The most obvious way for water to get into the braking system is by the brake fluid reservoir cap being left off of not sufficiently tightened.

Moisture can also enter the braking system through rubber hoses and seals.

Winter weather can result in salt from gritting entering the brake fluid. Drivers who own vehicles in colder areas (especially where it snows) should pay particular attention to checking their brake fluid.

How often should I replace the brake fluid in my car?

Most vehicle manufacturers recommend that the brake fluid in a vehicle is flushed and replaced every two years. In some cases the recommended period may be longer. If in doubt, seek the advice of a professional or refer to your vehicle’s service schedule.
