I don't remember is this the front or back brakes? Maybe there is someone out there that has swapped out there brakes that might have some spare parts. I will be swapping out the front for disk and rear end on my 52' after Christmas. Let me know if you need some of the parts. My rear brake lines look like they rusted through 20 years ago and the line was plugged off. I am sure the cylinders are crap but there are probably some usable parts.
