There is a very effective way for auto enthusiasts to reduce the brake fluid temperature overall during periods of high performance driving, and it involves making material changes to the brake caliper components. 

There are several different types of metals that can be used as a connective between brake pads and brake system fluid, and it is the properties of the metals that will affect the thermal transfer of heat from one to the other.

We are going to review the various materials commonly used in brake caliper components in this article, and discuss thermal barriers that can be used to further shield heat transfer to a brake systems fluid.

Stock Caliper Metals Used

Stock brake caliper pistons that come from the factory are made from steel as a rule of thumb. You might find that stainles...
