Is there some sort of valve on a SR that can keep the booster from getting vaccum? I've had a lot of brake problems lately, mainly a spongy pedal. So I bought a new master cylinder and bleed the entire system with a power bleeder. New the car stops fine, but you have to push the peddle extremely hard. I already checked the length of the linkage for the peddle and everything and it is fine. Any help would be greatly appreciated. Thanks.

I think there is a one way valve in line of the brake booster but Im not totally sure. Just check you main brake booster line. Also what year and was the car an Auto or Manual before and what brake booster did you get the Manual or Auto. The auto brake booster is softer than the manual due to it being larger and more range of braking.

your booster might be bad, the turbo creating all that heat right by it usually kills them pretty quickly.

There is a one-way valve, if put in backwards you get anti-power steering!

It's located right at the firewall where the 2 hose parts conncet together. Easy to turn around.

Oh my god, I am an F-in dumbass. I had that little valve in the brake line turned around. Hear all this time I've been spending time and money trying to fix my brakes and all I had to do is turn that dumb plastic valve around. Someone kick me in the ***....

Thanks for the heads up guys!!!!
