Welcome to the forum! The brake booster should not have been replaced - it has nothing to do with your symptoms. You either have (at least) two very substantial leaks between the master cylinder and the wheels or your master cylinder has given up.

Put the car on JACK STANDS and ensure that it is supported safely. Pull off the wheels and inspect the calipers in front for leaking. Then pull the drums off the rear and peel back the rubber dust boots on the wheel cylinders to check for fluid. Then check all the lines under the car for any leaks. If your calipers in front and your wheel cylinders in back are dry and the lines going to them are dry you need to replace your master cylinder.

You may have a combination of wheel cyilnders, calipers and the master cylinder failing, so it is important to check the wheels individually first and fix any problems there, then if the problem persists, replace the master cylinder.
