84-88 Carrera rotors are 24mm and 78-83 SC rotors are 21mm wide so does that mean you can use the Carrera calipers on the SC rotors but not SC calipers on Carrera rotors??? Paul S. (IMG:style_emoticons/default/unsure.gif)

Paul,
I wouldn't do it. Here's why, from a really practical standpoint: 99.9% of the pistons I see in calipers that need to be rebuilt have a rusty sludge that I call fluid shellac on the "top 1/3rd" of the piston. In all cases, this is caused by the piston being too far out in the bore due to old worn pads and bad dust seals and bad/old fluid. By having your pistons further out of the bore from day one is asking them to be subject to more of the elements from the start. It's a bit of a Mickey Mouse way of going about it if you don't have to and, it will shorten the usable life of the caliper. Solution: I have A-Caliper cores here if you want to swap for the Wide A-Calipers you have. It's not that one is more valuable than the other, they're the exact same caliper. The Wide A-Caliper has a... well, wider spacer in it. PM me if you want to do that. It would cost you about $10.00 in shipping. Problem solved. You get a better caliper for your application. |
