Went to fit my nice new braided lines and came to realise that my rear caliper needs a major overhaul as both pistons are seized. One is moving ever so slightly and the other is completely jammed Time to try and find some genuine seals and spend more money
Dave48 - Thanks for the advice So far most people seem to have suggested that splitting the caliper is absolute pain the ass and that the gasket on the inside is no longer available from Yamaha (but there is a part from another manufacturer, I forget which). I'm going to try and do it without splitting the caliper if I can - I'll re-attach the brake hose and use that to pressurise the caliper. Then, clamp on piston and force the other out, clean up that side, replace everything, then swap the clamp around and do the other side Hopefully the fronts will be ok and won't require quite so much work.Edit: For the seals, am I right in saying the kit is one per piston, not one per caliper... if so this is expensive
Just finished the rear caliper seals. It was a but of a pain in the rs without splitting the caliper, but do-able. My seal wiper rings were completely shot, and these were chewed up, locking the piston in. Brute force and ignorance got them out in the end. Putting the new seals in was a bit emotional, it always seems like they're too big until they finally pop in. Hopefully that's them done for the next few months!:
Sounds like they should be ok, but a good clean never hurts
