It seems my brake booster push rod isn’t long enough to reach all the way into the master cylinder; even after adjusting the booster push rod all the way out? I took everything off the 91 Volvo 940 turbo wagon. I Love the way it drives. Surprise power. Can I adjust the brake pedal hight by turning the pedal connect rod clockwise ? What would cause this new booster to be unable for its push rod to reach the back inside of the master cylinder?? It looks exactly like the old booster too??
