im going from my 1pot 5lug 89 gtu brakes to 4 luggers... will i have to change my master cylinder? im getting new rotors as well, will i have to get rotors for a turbo / GTUs or any 5 lug rotors will work? im also doing ss lines but that doesnt matter...

that doesnt make any sense. what i think you mean is that you are changing your single piston to four piston calipers.

 

yea i typed wrong, my bad... ill edit it for you
crap i cant... im sure you get the idea.. do i need to change the master cylinder when upgrading from 1 piston calipers to 4 piston calipers?

 

You don't have to replace the brake master cylinder, the 4 pistons calipers will bolt in; however make sure that you have the hard line (an extra piece that the 4 pistons calipers use, do a search under my name).

 

You'll need that same bakes as a turbo FC uses.

 

youll need (as stated above) the brake line coming off the caliper of the 4-piston........ as they are different from the 1 piston caliper....
