The 5. 2 Endurance dics pads fit 2008 and previous year model Marta and Marta SL disc brakes. The Endurance pad matter is largely metallic, which makes them less grabby, thus providing a smooth transition from off to on. Another benefit of these metallic pads is very long lasting, performance. The pad itself is designed to tell the user when to replace them. Namely, if the wear indicator starts clicking when the brake is applied, it's time to replace. The price is for two pads, enough to do one wheel.
