In 1965 no power brakes in any Barracudas, mine is a formula s and had no power brakes. If any were to have it mine would have as it had everything they came with as the top end model. Power brakes were a very rare or not existent in early 65 vehicles. I have since upgraded mine to front disc brakes and dual master cylinder and it stops great no need for power brakes at all, in fact I wouldnt want it. I enjoy the feel of my brakes as it is. The joy of feeling the road in early cars is why we love to drive them the most, in my opinion! What I hate the most is todays cars have no feel at all of the road period. My dad has a 2009 cadillac and it is a great car but you feel nothing driving it going down the road. I loved driving my 66 and now my 65 cudas as you feel the road when you drive. I always loved older nice cars also feeling the road when you drive. Today people do not even remember what this is...its ashame in my own opnion....
