Need some input here guys --- I noticed that the lever on my 85 VF500F was super spongy and basically goes to the bar, only minimal pressure. I bled the brakes 4x , fluid is clean and clear, no bubbles-- no improvement Bled the master cylinder and Tied the lever back for 12 hours -- no improvement Changed the Master Cyl for one that was on a VF1000R (worked when removed), re bled everything -- no improvement Calliper pistons move freely and the calliper moves when the lever is pulled, there is pressure on the rotor but not sufficient. If I leave it for an hour or two, when I go back there is absolutely zero pressure at the lever, straight to the bar, and after a few pumps I get some pressure back but not much. No fluid leaks evident. Next is a Calliper swap, unless anyone thinks I have 2 shagged master cycl's on my hands. My bet was Master Cyl, but im certain the one I used was working when it came off the VF1000R. not to say it couldn't be f'd now. Thoughts?
