Hello, I have a problem and have gotten some ideas on this problem but nothing seems to work for me. I saw a post on here from last year but did not get the full information about hard brake pedal and hard to stop 57 Buick converted to disk/drum setup with power. I have been working on my father's 57 and have this issue and can't seem to figure out what I need to do. Car was originally power brakes car from factory and continues to use the original brake pedal assembly. In the posts from two member last years they mention that a change is needed to acquire the correct pedal ratio so that it feels less hard. Does anyone have any pictures of a brake brake pedal assembly that has been modified or change and what did they use or what was done to correct this problem. I appreciate all the help any one can give me to fix this and get my father back on the road with his pride and joy (in the automotive area that is).
