So nearing the point of getting my Z back on the road and I am having severe brake bleeding issues. Its a 73 240z w/ Toyota S12+ (non vented), '85ish Maxima rear brakes with DatsunPartsLLC brackets, and 15/16 Master Cylinder, and braided lines front and rear. Calipers and master cylinder were good prior to install. In a hurry (because I was moving) I put the master cylinder, bled the system and actually had pressure throughout the system, it was loaded onto a flatbed and towed to where I'm at now. I finished installing the e-brake, ran the car and I have squishy pedal, no pressure or brakes until I pump the brake pedal 3 times. I pulled the Z back in the garage and noticed upon the 3rd or 4th brake pedal pump and on it would "hiss" at the last inch of pushing the pedal. I bench bled the MC, re-bled the system, and still the same story, no pressure until I pump the brakes in rapid sequence and on the 3rd or 4th press. Also I'm noticing when I bleed the rear brakes I'm barely getting any fluid coming out, or at least no where as near as much as I do in the front. I have no signs of leaking anywhere (lines, brakes, distribution blocks, MC, booster), and I am at a loss. I'm considering taking it to a brake shop and have them bleed it with a brake flusher (so it bleeds all 4 corners at the same time). But I'm on a budget and would rather save the $$. Any ideas?
