Default Brakes not stopping

HI, I have an 89. I got in it the other night and noticed the brake pedal was all the way up and very hard.My idle on my car is a bit low to begin with but i had to really give it gas cause it wanted to stall out . I started driving it but i turned around real soon. It was no fun to try and stop it.I think it's the power booster . I don't hear any hissing sounds. No leaks around the master cylinder. How do you get the power booster out.Do i need to be a contorshunist, or double jointed.How much of the interior has to come out.And does this sound like what the problem is.

Not that hard to do. Take out the hush panel and seat cushion.

Changing out the booster was the first thing I had to do with our new 86. First time I had ever done one and it took me 4 hours of work with maybe a 20 minute break to rest my shoulders. I don't want to have to do it again anytime soon but not the end of the world.

Disconnect the vacuum line to the booster and plug it. Carefully drive the car. Does it feel the same? Then you know the booster is bad.

Also, be careful with rebuilds they notorius for failures, I replaced mine twice in my 86, the first replacement didnt work, the 2nd was a charm!
