Track Wisdom

"Very high [brake] temperatures can also cause the brake fluid to boil with a resultant increase in pedal travel. This should be detected immediately by the driver, as a very small quantity of boiling fluid is enough for the pedal to go right to the floor without any effect; in contrast to the liquid brake fluid, the boiling part is compressible. It is particularly important that when the car has been stopped for a short time -- up to 15 or 20 minutes after a drive in which the brakes have become very hot -- the pedal is depressed for a check. When the car is at rest, brakes act as a heat sink from which heat spreads to the fluid contained in the calipers; brakes which were fully operative when the car was driven may have become totally inefficient after it has stood awhile."

-- Paul Frere, Sports Car and Competition Driving

How do brake heat shields reduce brake maintenance?

Our brake heat shields help to reduce your maintenance time and effort in a number of ways:
  • Brake fluid is protected from heat cycling with the use of our heat shields. Heat cycling causes a brake fluid to degrade over time, in extreme cases (boiling) it can be ruined very quickly. Hard Brakes heat shields allow you to go longer between intervals for flushing and/or changing brake fluid.
  • Brake caliper piston seals and boots are susceptible to excess heat, which can cause them to melt and eventually become brittle and cracked. When this happens to caliper seals it can cause loss of pressure and require an extensive caliper rebuild. When the piston boots become worn they can allow debris to enter the piston chamber which can cause a seized piston and severe loss of braking. The result is another caliper rebuild, if you are lucky, or a complete replacement.

Our heat shields are not as glamorous as a carbon fiber wing or a shiny chrome air intake system, but they do help to provide real protection for the most important part of your car, the brakes. In addition to saving time and money on the maintenance of the braking system, our heat shields also help prevent expensive off-road mishaps that can severely damage the rest of your car.
