Hello to everyone out there. My name is Matt and I am from Detroit. I'm working on a crazy bus here and looking for some help. I have a 1990 Marco Polo Coach on an Oshkosh chassis. This thing has an air operated parking brake with a "Rotor" mounted on the tail shaft of the trans. Basically something happened to freeze the caliper and my pads are destroyed. Caliper seems to operate fine now, but I have to replace my pads. I have been on the phone, internet, and everywhere else I can think of looking for a set of pads with no luck at all. I used a picture of the pads as my "Avatar" to register on the forum. Anyone out there ever seen anything like these before?
