For maximum braking performance, choose a brake fluid that offers high dry and wet boiling points, and consider replacing brake fluid on a regular basis. As a glycol brake fluid gradually and inevi- tably absorbs airborne moisture, its boiling point begins to decrease. A moisture factor of as little as 3% or so can allow the brake fluid to boil at under 300 degrees F, which will lead to reduced braking effectiveness. Regardless of the vehicle type or perfor- mance level, maintaining the brake system's fluid purity is important both to maintain system performance and to reduce internal contamination. If the customer expects maximum braking performance, the brake fluid should be changed according to the vehicle manufacturer's recommendation (or if no recommendation is listed, changing fluid every one to two years would be a rough guideline). ■ High-dollar luxury performance cars often fea- ture premium-performance brake components such as multiple-piston calipers and large diam- eter rotors. This example is featured in 2009-2012 Mercedes-Benz AMG vehicles, featuring 6-piston calipers and ceramic-compound discs. You're not going to find these at your local parts store.
