the pressure in my brakes started to feel weak so i checked my brakes to see if they were bad and ended up it wasnt, so i tryed to bleed the system to see if that was it , the brakes got stiffer for a little the went soft again , im thinking its the master cylinder but not sure, well just wanted a little of advice before i go out and but something i dont need , thanks

 

Does your car have ABS?

If not, and you arent leaking anywhere else, I would say its your brake booster. You can prolly find a used unit with the master attached for pretty cheap. That way you eliminate both possibilities, but I am almost certain its your power brake booster.

no abs , and im pretty sure theres no leak, if so where would it leak from, so how much would the master cylinder and brake booster together go for

 

If I were you, I would post a WTB link in the 2nd Gen forum. there are quite a bit of ppl parting out their 2nd gens. Actualy I know a guy that lives nearby I will give him a call for you.

 

If the master leaks it will be right where the junction of the booster/master, (that I have seen leak). The booster will not leak, it will just not provide assisted braking if it malfunctions. I would also check the vacuum line that goes to the booster and make sure there is vacuum there when the engine is on otherwise, there is your problem.

hehe
good luck
