why do 200x rear calipers always freeze and how do u rebuild them?

[kilabeez0]

just like it says, i snapped one bolt off the top of my "better" rear caliper and called it quits after demolishing the first caliper. it's been soaking in rustek and coke cola becuz i heard it works good. any help here?

I assume your talking about how the caliper seizes to the float pins? I believe it to be from probably 20 years of never being greased. If a person were to get one free, buy new rubber seal things for them, and take it apart every year there probably wouldn't be any problem... same as with 200x swing arm bolts.

To get my 350x ones apart I used a bench vice and sort of used it as a press. I've been finding out after doing 2 rear calipers and 1 front caliper from 350x's that there are bushings that come out with them, the bushings have a cut in them, so I take them off the pin, push them back into the caliper, buy new rubber seals and probably new pins and reassemble with lots of grease or antisease. With this one front caliper I did I had to use a propane torch and put direct heat on the aluminum to help expand it, it seemed to help alot, but might end up ruining the piston seals along with any other rubber that still might be in the caliper.
