Maintenance History:

Periodic inspections, pad changes and caliper service – brake rotors remain in service, 6+ years later. Subsequent pad changes since initial brake job – Front pads replaced twice and rears 4 times. Test drive at inspection produced rotors temperatures of 390F at front and 580F at rear. Rear axle disc pad changes during the service life of the brakes were double that of front pads (4 pad replacements at the rear axle and 2 at the front axle), and is consistent with the higher rear rotor temperatures observed during test drive. The City of Seminole, in Pinellas County Florida, has been using Power Brake Diamond Technology® rotors since 2004. Their entire fire/rescue air brake fleet is outfitted with Power Brake rotors, thereby dramatically improving fleet reliability while maintaining the highest standards in brake performance and vehicle safety.
