If the brake pedal on a 1987 buick regal t-type presses hard but not to floor and takes all of your weight to stop it is it the powermaster brake system?

2xxbqYes and no. There's a series of diagnostics to follow to determine the cause, however the most common one is the accumulator ball (the black thing on the side of the unit). They lose pressure over time unti they need to be replaced. Look to http://www.gnttype.org/techarea/brakes/PwrMstr.html for more information. Hope this helps!

What happens when air gets in the braking system?
Air stuck in the brake lines cause the peddle to feel "spongy". Your braking distance will dramatically increase with air in the system. When you apply the brakes in a vehicle that has no air in the system, that pressure added with the pressure from the master cylinder presses the brake pads against the rotor or drum causing you to stop. When there is air in the brake system and you apply the brakes some of that pressure is used up by compressing the air in the system and the rest is trying to stop the vehicle.
Where do you apply the anti squeek?

What is the difference between a spring brake a parking brake and an air brake?
A parking brake is any system which is intended to be used when a vehicle is parked, whether it's a spring, a cable, or any other device. A spring brake has a spring which constantly presses the brakes to remain engaged.. during normal operation of the vehicle, a quantity of air is supplied to push against the spring so the brakes remain released. Air brakes simply mean a braking system which uses air for actuation instead of fluid.
Why is it that when you turn the steering wheel it presses the brakes?
Does it actually engage the brakes, or just the brake lights? There should be no possible way for the steering wheel to actuate the braking system, but a short in the wiring somewhere in the steering column could be causing both rear signal lights or brake lights to come on.
