Best brakes that will still work with 14" rims?

Well like the title says..... I want to keep my 14" rallye rims but I want good brakes too. Would like to have disk brakes front and rear. My car is a 70 swinger two door and I believe they are 9" drums. .... You measure inside the drum right!?!?! Sorry brain fart.... Any help is greatly appriciated!!!!

Also rims are the BBP. And the plans are for 8.75 rear.
