Decrease the Temperature of Your Brakes
CoolShims® are “drop-in” brake coolers that require little or no vehicle modification. They are mounted between the brake pad and caliper piston and are as easy to install as a new set of brake pads. They conduct heat from the caliper piston to a heat sink located externally to the brake caliper.
In dynometer testing at Greening Laboratories of Detroit, Michigan, CoolShims® lowered brake fluid temperatures twenty percent and prevented brake caliper failure on a Meritor Quadraulic truck caliper. Separate, independent testing has also shown significantly faster cool down times for a caliper employing CoolShim technology. CoolShims® are effective and are much more economical than full brake system upgrades. Furthermore, they can be designed to fit almost any vehicle and generally last for the lifetime of the vehicle.
