Enlighten me in this question please. What are the symtoms of a bad brake pump? And thanks in advance 

Come on people a little info here please

your brakes not working. If you have to slam the brakes to the floor. I've never heard of one going out though. And I have an 89. Felt like my brakes were bad after we swapped the rear axle and had better brakes on it and bled the brakes they work like a champ now

What's a brake pump? Do you mean the master cylinder?

Yep that's it

Google search revealed this good article for Master Cylinder troubleshooting:

does your peddle go to the floor? or slowly lose pressure and sink to the floor.
if its rock hard and you have to press real hard it could have a vacum leak off the servo.

go to a breakers and get another, as i cant imagine there that expensive.
