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

Titanium brake shims vs big brake kit upgrade.

If you are tracking a street car with stock brakes, you may be experiencing that the brakes are not up to the job for stopping your car lap after hot lap. An expensive option for your car is to upgrade to an aftermarket big brake kit (BBK). While this may be the ultimate upgrade for many serious racers, there are a few drawbacks to consider.
  • Cost. Our titanium brake heat shields, racing brake pads and a bottle of racing brake fluid are a much cheaper alternative to a BBK upgrade that might just be enough for your needs.
  • Reversibility. If your car is under warranty, there is a good chance that the dealer will flag it for possible warranty rejection if they notice that you have upgraded the brakes to a track model. Our titanium brake shims can be removed in just a few minutes so that the dealer will never know about your upgrade.
  • Order of Upgrades. Unless you are sure that you need the full power of a racing brake kit, why not start with the cheaper options first? We usually recommend to start with an upgrade to racing brake fluid, followed by racing brake pads and titanium brake shims, then brake cooling ducts, and finally a full upgrade to the BBK if it is still needed.
  • Series Regulations. Many racing series require the use of stock brake calipers, for which a BBK upgrade is not an option.
