Re: '40 rear brake question: How snug should the drums be on the shoes?
Quote:
And in rethinking the differential of pressure thing, While a first thought would be different lengths of actuating levers, I think that approach would produce an equal pressure at first movement, but with increasing pressure on one and decreasing on the other, very soon achieving 100% pressure on the set having the longer levers. I’ll go back to my method, which effectively delays rear shoe movement, while maintaining the differential percentage from light braking through panic braking. Now you must excuse me, I’m off to gobble some aspirin.

I Installed the Boling Bros kits on my "46, and had the same problem as my4dv8 had. Solution was the same, sand to correct the lining radius. If you look at the measurements noted in the attached picture, the thickness is reverse to what it should be; thinner mid lining than at the ends. The other problem was, the park brake cable spring was too long, and would become coil bound, preventing full travel of the arm to apply the park brake.
