I'm redoing the brakes on my 86 trx350 and I wanted to know if it's really neccesary to hone the wheel cylinders. I have all four wheel cylinders off the bike (The owner before me lost the cap and diapragm off the master cylinder so the lines were contaminated with water). So far I've cleaned up both cylinders on the left side and there was no rust to be found, just gunk from the open resevoir. None of the four cylinders were leaking into the brake drum and as far as I can tell all seals are in good shape. So I'm thinking that all I need to do is finish cleaning up the right side, clean out the lines and remount. Am I asking for trouble doing this? Parts are notoriously hard to find for these bikes and I'd like to keep the cost to a minimum. All comments and opinions welcome.
