Chosen by the US Post Office after extensive testing of multiple brake parameters.
Racing improves the breed. We've applied what we learned about racing brakes to road vehicles, and now offer brake rotors and pads to qualified fleets. Use of cryogenically treated brakes can save hundreds of dollars per vehicle per year. Recently the United States Postal Service sponsored extensive testing to determine what the best brakes were for its fleet. Our Precision Fleet Brake brand brakes were judged to be the best of all rotors tested.The second place brake showed seven times the wear.Fleets such as the US Postal Service have considerably reduced operating costs by using cryogenically treated brakes.
We've had treated and untreated brakes tested by Greening Testing Laboratories and Link Laboratories according to SAE 2707 JUL 2004 METHOD B, both independent testing labs that are well known for their work with brakes. They found that brake rotors and pads lasted significantly longer after cryogenic treatment, with no significant change in braking effectiveness. In some cases treated brakes have lasted four times longer than untreated ones.
Another test performed by Link Labs for us involved two rotors that were cycled according to SAE 2707 JUL 2004 METHOD B until the untreated rotor was worn beyond its service limit. The treated rotor was then put through the same cycles. It finished the test with 0.039" less wear on the treated rotor.
Why would you send your police out with inferior untreated rotors?
