FE570 Won't Bleed Rear Brake
I have a bit of a problem that has been racking me for quite a while now.
Last year on my last ride half way through I lost about half of my brake travel and only got a little brake when the pedal was about 3/4 down. At the time I thought it was just low on fluid so I never thought much of it.
Last week I put fluid in with no change. I checked the brakes with my hand and it still felt very soft, but the caliper was firm on the disk. I then pumped, held the pedal down and cracked the bleeder, and from then I have not been able to build pressure up on the caliper.
I have taken the master cylinder off and cleaned it. It did have some dirt. I reassembled but after tightening everything and filling the reservoir up, I pumped held down and released bleeder about 50 times but no fluid went gets pulled from the reservoir.
Any help or suggestions here? I am wondering if the seal in the master is gone, or something in the rear caliper.
