Ok so i replaced my master cylinder and had to use my resvoir of my old one, but it seems it didnt help, ive bleed all of the lines and it still isnt building pressure, i can see air bubbles coming out of one of the tubes going into the mc, the air bubbles come back into the resevoir can anyone help with this please, i bought this car and stil havent been able to drive the darn thing!!!!!

 

You need to bleed the master, search on bench bleed...
Essentially, there are pistons in the master and you have air in the "cylinders". Until you fill that with fluid, you will be blowing bubbles.

sorry for not mentioning but i did bench bleed the mc and this is this the current problem, i was told today possibly the combination valve or the proportioning valve not sure which one is on this car......anyone else think so?

 

Remove the proportioning valve, take it apart, clean it, put back in use...
But I suspect you still have air in the Master...

 

yea i will take apart th proportioning valve and take a look at it and go from there, i didnt know it could be torn apart this one dont look like it can be, and the whole thing i dont understand is why there is air coming back into the resevoir after i pump it,so obviously i have air coming in from somewhere i truly need help with this pretty baddly, if someone is in the Cleveland area then that would be pretty sweet if they would like to come take a look at it.
