Buying the Best Brake Rotors and Pads? It Might Be Time to Change the Brake Fluid!

Friday, June 28, 2013 by Zig Ziegler

Brake fluid supplies the caliper hydraulic pressure needed to clamp the brake pads onto the rotor and provide stopping power. It is also subjected to high amounts of heat in disc brake calipers. However, hydraulic braking systems are not 100% sealed from moisture and over time the fluid will retain more and more water. Typically, brake fluid has a dry boiling point of over 500°F, whereas water boils at 212°F.

The problem with too much moisture is that the boiling point of the brake fluid significantly drops to the wet boiling point, which can be around 200°F lower than the dry boiling point. Boiling point is significant because when something reaches its boiling point it vaporizes and vapor is highly compressible. Since fluid is not easily compressed, when you hit the brakes with dry brake fluid it provides a smooth, stiff pedal feel. Yet, when too much moisture is present, the brake fluid boils when in the caliper and compresses, which gives that spongy pedal feel.

When changing your brake rotors and pads, consider replacing the fluid as well to get the most firm pedal feel and shortest stopping distance. We offer a full line of track and street brake fluid to complete any full service braking system replacement. Most brake fluid systems should be flushed every one to two years in non-track driving conditions and more often when tracking your vehicle.
