Originally power brakes, took off power booster, and all abs equiptment.
On first application the pedal is high, and hard. I put car in gear and it starts to get spongy.
Wheels are on tight. Calipers were put on new when I built the car, pads are the cheaper (more organic) didn't have any problems except for the need for excessive pedal pressure. I'll check runout, but they look okay

I'm beginning to wonder if the vibrations some how cause leakage in the master cylinder.
I've thought about replacing the master cylinder next. But not sure if I should get a stock replacement, or an aftermarket one. I originally figured the stock one should be fine because I'm using the stock calipers etc. All I did was remove the power booster, and the abs stuff. put in a proportioning valve. Then change the pedal ratio.
Another thing i had to change was the stock system was right front, left rear on one part of the master, left front right rear on the other. Now it is both fronts off one end both rears off the other.
