Ok guys, I had a Stock N/A Supra, and I recently did a swap, now im turbo stock. Here's the problem, When I press the car hard and then try to brake, The brakes stiffen up meaning I get no brakes until i let it free up for a couple seconds, But this ONLY happens when I press the gas hard and then suddenly try to brake. What could be the cause, and how could I fix this? If I was to try to make a sudden stop if someone cuts in front of me, i'll be done basically. Trying to fix this problem asap, I dont go around everywhere pushing the car hard, But I rather fix this now than ride it out. Stick btw.

BK, as Ian said check the hoses and check valve to brake booster. You could easily have overlooked it during your install. It may be as simple as re connecting the hose itself also.
After you turn the car off do you instantly get a hard pedal or do you have a few regular pumps before it goes hard?
The check valve has to face the right way, if you blow into the booster it should stop flow.
If the valve is damaged or installed backwards when you come on boost it pumps the booster up and you can't push the pedal.
