ok, my `57, disc brake conversion up front, factory brakes in the rear. all new pads, rotors, lining and drums. even before i put the new stuff in/on, why can`t i lock up the brakes? thanx.

Perhaps your tires are MUCH larger than tires typically being used with those brake systems. When you 'Lock Up' your brakes, generally you know it when your tires break friction with the surface. If there's much more friction/stiction from the tires/road than the brakes it will be difficult to lock up the brakes (maybe try it on a wet slippery surface)..
Are you able to STOP when you need to and quickly enough? That's the real key...
55&56 Here with Camaro/Chevelle Style disk up front and 57 Olds 11 0r 77 Cutlass 11 drums on rear no issues. I used second gen Camaro second gen Camaro prop valves.
factory is 11 inch, right? thanx for the replies!
Correct, I thought 55-57 was 10.0 but its been so long since I had stock brakes. Rock Auto says 11.00 for 55-57. I had 9.5 rear when I had a 66 Chevelle 12 bolt.

and yea, i guess i can stop fast enough. just thought it could be better.
255/60x15 on rear 205`s on front. thanx
When you say you can't lock up the brakes, which would be a good thing, what master cylinder size, how much pedal travel, and how hard you are pushing? Brake pad compound can make a difference, along with many other things. I'm setting up my car for manual brakes, but I have to custom make the brake pedal mount, and I'm worried about pedal flex because I will need a lot of pedal force, even using a 7:1 Wilwood race pedal.

all stock chevy, and i`m really pushing on the pedal. and, rear drums, after driving around town get super hot, can hold my fingers on them, but not for long. so i guess there are adjusted as far as i can go? e-brake cable has play, loose.
