If you have no hydrolic pressure in your breaks, or in other words your breaks dont work very well.

Yes. The engine will idle poorly when a vacuum power brake booster goes bad. It can be a source of a large vacuum leak. A bad master cylinder however would have no effect on the performance of the engine.
Master cylinder is bad and appears to be coming from the booster.
THE ONLY WAY TO TELL IF THE CYLINDER HEADS ARE BAD IS BY REMOVING AND INSPECTING THEM.(NO ONE IS THAT GOOD AS TO BE ABLE TO TELL WITH OUT LOOKING) THE NORMAL PROBLEMS THAT YOU GET THAT ARE CYLINDER HEAD RELATED ARE NOT ALWAYS DUE TO A BAD CYLINDER HEAD.
Sounds to me like your Vacum booster behind the master cylinder is weak or bad!
Is a bad thing and requires IMMEDIATE REPLACEMENT OR REBUILDING OF THE MASTER CYLINDER TO PREVENT SERIOUS INJURY AND OR DEATH
the leak between master cylinder and booster is where difference type of gasket is worn out depended on the type of your vehicle...older vehicle usually have flat gasket but mostly have O-ring Gasket the need to be replace. you have a bad master cylinder its leaking fluid into your booster the seal or oring is just to prevent vacuum leak change master cyl before the fluid attacks the booster and you spend another 170.00
this is most likely caused by a bad brake booster. hook up a vaccum pump to booster and see if it holds vaccum, if it does, its ok, if it doesnt, its bad. booster is located between firewall and brake fluid resevoir, you will see a large diameter vaccum hose connected to it, this is where to test it at.

There is a gasket between the master cylinder and the booster of a 1990 Acura Integra. It is shaped like the side of the master cylinder with two bolt holes.
The power brake booster on a 95 Chevy Blazer is replaced by draining and removing the master cylinder, unbolting the booster, and removing it from the vehicle. A new cylinder is then put in its place and bolted on.
