I can't figure out what's going on. I am going to take apart the whole back braking system including the master cylinder and inspect everything. I have already proved out the caliper and pads. They work great. I used a vacuum bleeder last weekend and it worked great and i got the fluid flowing out crystal clear with no air bubbles. Still didn't fix my problem. I can get the back brake to work if I pump it a few times, but that's ridiculous. My bike only has 4,500 miles on it and I'm super frustrated with this issue. I'm starting to wonder if air is trapped in the master cylinder. Do I need to pump the brake pedal to get that last bit of air out before close the system up? This is a simple system and I can't believe I am having this much trouble with it.
