This is the setup I am using:
When my pedal is at it's neutral position the booster linkage and pedal pivot are pretty much straight up and down from one another, but I don't think that should make a difference since I have the booster shaft fully extended out in the pedals neutral position.
I also noticed when I apply the brakes with the master cylinder lid off that fluid will jet up from the bottom of the resevior. I take it this is normal?
I noticed in the picture of the GM combo valve below that it says to hold the metering valve when bleeding the front brakes. I have just been bleeding the brakes the conventional way with pumping the pedal. Is this metering valve really necessary to properly bleed the front brakes?
