The OTR Copper Free Air Disc Pad is designed to minimize rotor wear while still being copper free. These pads are post cured and treated with aluminum oxide to eliminate the need for an initial break-in period. Independent test labs have confirmed that these pads wear less and have less material loss compared to multiple OE edge codes. The pads are also mechanically attached for increased shear strength and improved heat transfer. This ensures that your brakes will perform optimally and last longer.
