Brake Fluid

The brake fluid in your vehicle is probably the most neglected fluid of all. Brake fluid is “Hygroscopic” which means that it absorbs moisture from the atmosphere. What does this mean for you? When brake fluid reaches a moisture content of 3% the boiling point of the fluid lowers down drastically to 329°F from 500°F when it contains no moisture. When braking at high speeds, down hills, and heavy traffic will raise the temperature of the brake system and at time the fluid will boil if it reaches its boiling point. As soon as it boils it create air pockets in the system and the result is reduced or no braking. The moisture also will start to corrode internal brake components such as the master cylinder, calipers, wheel cylinders, and ABS/Traction control units. We recommend service every 2 years, when the moisture level is at 2%, and if the copper content is too high.

Your brake system will benefit from performing this VERY important service. You will have peace of mind when braking, extend the life of the cylinders, and will greatly reduce the risk of major components from failing.
