I have a 9" rear '57 from my investigations, small bearing I know for sure. Didnt come with brakes or backing plates. had a thread a while back about using brakes from an 8" rear, offsets and crazyness, wanted to find correct brakes. I found a local guy selling a set off his early 9" small bearing. I was installing them this weekend and realized, all components for the ebrake are missing. I called and asked him if he had them, he said you got everything with it that was removed....said he never had an ebrake on his car. Just my damn luck. I thought maybe I could use the parts from the 8" rear brakes (which are also 10"), the park brake strut dont seem to fit right, too short, so they must be different. the brakes I bought are 10" x 2". Can I just get parts from the yard from any ol 9" rear, or would the parts be different depending on big bearing, small bearing, different years, etc..? I dont know for sure what all is missing (dont have diagram for 9"), but I know I dont have the parking brake lever (that sits behind the shoe), and I dont have the parking brake strut and spring. Anyone say for sure if this is all that is needed for the ebrake, and how easy it would be to source at a yard or parts store? thanks!
