stiff brake pedal

hey guys, im in a 89'fleetwood front wheel drive. when ever i start the car and push the brake pedal to switch gears, the pedal is very stiff. So stiff that it wont move at first so i have to pump a couple of times untill it lossend up to normall. Its been like this for a while probaly about couple of months. My brakes also fad when sitting at a red light. Ive had trouble with the master cylinder before and its been fixed like twice about a year ago or 2. Is it possible that there is just air in my lines and i just need to blead my brakes? What do yall think?

Do you have vauum or electric power brakes?

i think someone told me once that its a vacumm, but im not sure. is there a way to tell? and what difference does that make?

Vacuum brakes has regular type master cylinder and a big round metal can behind it, and works on engine vacuum.Electric power brakes are tied to teves anti-lock brake system, to make it simple has master cylinder top is not a rectanglelar, no vacuum hose from engine, several electrical connectors and switches.there is a big $$$$ difference, and approach to how to correct

u think it could be air in the lines if its vacuum brakes?

It's unlikely

looks like it has been fixed already as this thread's kinda old. but if anyone drops by with the same problem, i would suggest to check them pistons.  they get kinda rusty (not too much) and makes braking a bit stiff.

as for that brake booster thingy, it looks like this http://www.car-stuff.com/store/images/prodimage/images/a1_cardone/A15474826.jpg

also, if you are having trouble with your brakes, it is always a safe bet to check all brake system components.  i learned that lesson the hard way when my old escalade (pre-owned) had a problem with the brake fluid lines which i got fixed right away but failed to notice that my Cadillac Escalade brake pads need replacement too.
