phil4 Posted July 24, 2016 Share Posted July 24, 2016 there is definately fluid passing through the whole system because it bleeds perfectly, it just wont pressurise Ok, so why not take the (perhaps misguided), approach I outline above.Start at the top, undo the brake line, finger over the outlet, pull the lever. So you have pressure there or not? Attach brake line, block off brake end, finger over it, pull lever, do you have pressure?Just work your way down checking for pressure.Always always narrow down the problem area it'll always help.Sent from my phone.

gsxr_rory Posted July 26, 2016 Author Share Posted July 26, 2016 I was pretty sure there was a problem in the system somewhere and I was right, I spilt the NSF caliper to find one of the upper dust seals had worked it's way half out past the piston jamming it completely so it's rebuilt now ready to refit and re attempt bleeding Quote Link to comment Share on other sites More sharing options...
gsxr_rory Posted July 27, 2016 Author Share Posted July 27, 2016 ok well ive rebuilt the calipers after one of the seals had come displaced and wedged between the caliper and the piston, I have re-installed the calipers to the bike and re-bled the brake system, i now have pressure in the lever but it's only about 50%,any ideas?
