After having a braking problem on my last ski trip(the 2 threads below explain in detail), I decieded to start the troubleshooting by bleeding/flushing the brake lines. I built a diy pressure bleeder. The pressure bleeder came together fine.
I started bleeding the right rear drum and everything looked like it was going good, pumped it to 20#, opened the bleed valve and lots ugly very dark brown fluid coming out. After 4-5 min it started blowing air. Looked at the MC resivoir and it nearly empty and guage at 0. Appeared little/no fluid transfered to MC.
Long story short, after checking "nearly" everything; more fluid in pressure tank, ect..I got to this weird point where I was getting pressure buildup (20#)
but no flow to the bleeder nipple, so the pressure bleeder appeared good. I decieded to call it quits and put everything back in my tiny garage. I deciede ot give the pressure bleeder another look and sure enough, the pick-up line had come out of the fifitting at the top of the tank where I could'nt see it but was still pressurizing the tank. I should have realized something like this was problem when I didn't see fluid flowing from tank to MC>
My quandry is why was it showing pressure w/ the bleeder nipple open and the pressure showing 20#. And is there anything I need to do before I try bleeding brakes again?
Also, Emerg Brake and Rear ABS lights are on.
Note: Pressure guage is in-line almost right at the MC cap, and although I'm looking for any feed back, lets assume no problems w/ the pressure bleeding apparatis
