You must be cautious as there are some of the rebuild kits out there  
are crap. The seals have the wrong cross section and will not allow  
the pistons to go in with out damaging the seal.  If you try the seal  
on the piston prior to installing it in the caliper the seal should  
just be a snug fit on the piston If you look at the seal you got it  
probably is a sloppy fit. So when it is installed into the caliper it  
is now to tight to fit the piston.
