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

Will these fit with new pads?

Yes! Our shims are designed to be thin enough that they will fit with even new pads (roughly 0.5mm). You may find it necessary to break in the new pads with a bedding procedure before the shims will fit.

As your pads wear down, you can "stack" our shims to make up for lost brake material. This will actually decrease the amount of heat that gets to your brake fluids as your pads wear down.
