brake problem

[dwpred50]

Hey, today I went to drive my 1988 mustang around after changing it from efi to carb but my brakes will not work.It is rock solid. I assume its because of the abs and computer system that i took out. I know I probably have to get a new master cylinder am i right by thinking that? and is there anything else i have to change. Any help would be great.
thanks

I'm not really sure, but i don't think you had abs.

No abs on a 88 mustang no need to worry.. But did you remember to hook the vac. line back up to the brake booster??

where exactly is the brake booster?

Its what the master cylinder attaches to. There is a vacuum line that runs from the booster to the intake manifold.

Does it attach to the back of the carb?...theres a pluged hole on the back of mine where a vacum line could hook to.

They work now thank you guys so much. One more thing I can't remeber back when i used to drive that car on the street but are the brakes on a 88 ussually kind of stiff. Once again thank you guys.
