I have a 86 TRX200SX that my kids ride and the front brake wheel cylinders leak rather excessively on it. These are not available from Honda any longer as complete units and I have rebuilt the originals as the cups are still made. My cylinders have small pits internally and still leak even with new cups. After about a month the shoes and drum are soaked. Has anyone out there tried to interchange these with some from a later model quad? I know the new Recon's use drum brakes up front but wanted to ask if anyone else has run into this issue or even know if something like that would interchange... Thanks in advance!
