HI Im trying to find out if you can, or has any one used the hand brake system From a 1.5 ton 1950 BIG BOLT AD truck and used it on a 1/2 to 1 ton AD pickup. It seems like a much simpler system with no rear cables or linkage to deal with and I think its the same 4 speed transmition used on 1/2 10 1.5 ton 4 speed on the floor with granny gear,I think its called a sm420 ,or 320? The emergency brake system looks like a small brake drum with with a brake band that tightens when the brake handle is pulled,very clean and simple,hope fully someone has tried this and can help me with ideas on how to make this atempt Thank You Green 48
