Well i have done a ton of searching and i have a lot of ideas but i am not sure the direction to go yet. Here lies the problem.... i have almost no brakes at all. Pump them up with the truck off they seem fine, start it and the pedal goes to the floor. I have used a Vac to bleed them and the traditional "girlfriend method". Nothing but fluid coming out. It has me seriouesly reconsidering all of the brake work i have already done. I attached some pics for reference and some dumb ass newbie questions listed below. Here is what i do know. Master Cylinder- 1 1/8 Speedway PN 910-31440 BOOSTER- 8 DUAL DIAPHRAM BOOSTER Speedway PN 910-31435 PEDAL ASSEMBLY- 47-54 CHEVY PU Speedway PN 910-31977 Modified the pedal a bit to work in the IHC. Ratio is 5.5/1, 1 1/4" travel for the push rod. 1. Is my e-brake properly adjusted? I hear this can be an issue. 2. 2lb residual pressure valves i know are leaking and but do they need to be closer to the MC? Right now the front is about 12" the rear is about 24" from the MC. going to get some from ECI i think. 3. Do i need a combination valve? Right now i just have a wilwood proportioning valve going to the rear brakes. 4. Maybe my calipers are holding air? I am about at wits end with these brakes right now. Hope the experts can shed some light on the subject. Thanks in advance.
