So I'm getting to bleeding my brakes. I have replaced every item with parts from PMB. That's all the hard lines, soft lines and all calipers and pads. The installation was pretty easy but I'm not beyond making mistakes. The stuff has been sitting a while, installed with no fluid in the system.
Please note that I've done this on quite a few VWs so bleeding brakes is not foreign to me. I just did this exact process on my '89 Westy with good results. (IMG:style_emoticons/default/sheeplove.gif) I can get a steady stream of fluid through all bleeders both with a vacuum pump and also with pedal action I see no signs of leaks I get no pedal and it seams that the pedal won't actuate any of the calipers (More on this) with normal action. This morning I went though all the calipers and moved a considerable amount of fluid though them by pumping the pedal with similar results until.... I pumped the brakes a bunch and finally got action on the front brakes but then they were stuck. No action on the rears. I did not bench bleed the master. I did crack the hoses on the master until I got fluid from each of them. I have speed bleeders installed, so far I am not a fan. What could I have messed up in the install? Why are these things sticking? Next step? Thanks..... |

Another recent brake thread just reminded me:
Are the bleeders on top of the calipers? If they're not, you will never ever ever get a good pedal, no matter how much you bleed. We've had people try to use the bottom bleeder on calipers that had two, and we've had people swap calipers left for right, giving them only a bleeder on the bottom. The air never comes out that way. --DD |
