You 'boiled' it off. I just replaced front and rear pads so I would pass state inspection next month, and be safe to make 2 upcoming out of state trips. I had a friend do it, who owns his own bike shop. He also changed my clutch and brake fluid, makes sure all is working as it should, and charged me $100 for his labors and fluids. I bought the OEM pads. Your calipers probably seized. Bet they will need re-built.Just replaced front pads and on first longer ride I noticed the front brake was dragging thank god I had slowed way down because the locked up totally then after inspection the master was way way low and there was nothing was absolutely no front brake. Strangest part there's no sign of any leaked fluid anywhere. Anybody have any ideas?
