partner. you are making it too difficult. the calipers should not be split unless leaking. they come off as a unit. personally i wouldnt remove a caliper to clean anything unless i needed to change a rotor or actually replace or rebuild the caliper. kits for the o rings you need are available for cheap. or you can use the rebuilt units you mention although i cant speak for them.

Did you separate the two halves of the caliper? If it is an ATE, you're really not supposed to. Even when replacing the piston seals, you don't need to separate the halves.
If that is indeed what you did, you probably wont find those seals anywhere.

Thanks guys, indeed I did split the two halves open.Tom you said I could get the o-ring set, where could I find it? You guys can believe me this will be the last time I ever take the caliper off in two parts.

Good luck with the seals. If you do find them, you might need to check with ATE about the torque specs for the halves. In the manual, it says not to separate the halves because they are torqued unequally at the factory.

that sounds like you will have to buy the rebuilt calipers. i must be wrong about brian splitting them. now that i think more i believe he must have changed the puck seals and dust shields only.
