Another brake bleeding thread, ...but this one is a little bizarre Options

[tomeric914]

First, what I have. Fairly new 19mm master cylinder, fluid changed every 6 months or so, car built mainly for DE's. All calipers in good order. Fronts are aluminum Brembo AM calipers from Eric Shea with stock 911 size pistons.

Now the bizarre part. While bleeding the brakes using the buddy method which has always worked for me (push down, open bleeder, close bleeder, pull up), I get very little fluid out of the fronts. What I noticed is with no pressure on the brake pedal, if I open the bleeder valve, more fluid gets pulled back through the bleeder tube than when pushing on the pedal! This is how I get the best pedal though it isn't as firm as I would like.

So I took the feed line closest to the front of the car off to make sure nothing was blocking the port. I also pulled the grommet and the little spacer washer below the grommet out. Everything was totally clean.

This is too weird. Does the front feed line on the MC feed the front brakes as would seem logical? I'm at a loss why it won't bleed normally. (IMG:style_emoticons/default/WTF.gif)
