I have damaged my ABS sensors from overheating my brakes coming down a long grade without the pacbrake working. (Both rear sensors had fallen out of their mounting sleeve and banged around against the tires and came apart into bundles of twisted fine magnet wire. I haven't checked the front ones, but I plan on replacing all four.) My 99 Contessa Naples, Magnum chassis, has the Wabco ABS controller, so I imagine the ABS sensors are probably Wabco as well, but I don't know the part number or how to locate it. I see several devices on line that look like they might be similar, but the remains of the sensors are so mangled (half of them broken off) that I can't really visually verify.
Does anyone know what the part numbers might be for the rear ABS sensors and the front ABS sensors?
(P.S. I visually checked my rotors, and also felt their surfaces, and they are smooth and without checking or discoloration from the overheating, and my brakes have been working fine the 1000+ miles since the overheating. I think the overheating was just enough to cause the sleeve that holds the sensors to expand and allow the sensors to loosen and fall out of the sleeve, leaving them to dangle free and bang against the tires until they were physically destroyed.)
