I have a set of the steel accessory brake shoes. When I tried to use them previously there was not enough clearance even with a pretty thin lining. I've looked at earlier posts on lining these with countersunk tubular rivets and the finished shoes are always shown before the cam is rotated to expand them. Would like to know how they got them to fit in the drum.
What do you consider thin lining? Which accessory brake shoes? There are many different types.
By the way that what a disk sander on your table saws for!
Mark, if the lining is not too thick you may have to adjust your brake rods longer so that the brake shoe relaxes more and does not rub on the drum when you push the lever forward. It would help us determine exactly what your problem is if you post pictures of the shoes that you have on the car.
The shoes have to be made smaller so that there is room for the shoes to expand before they touch the drum and lock the drum
When the hand brake is off and the T is in high gear the cam is horizontal and the ends of the shoes are at their closest point.
When you pull the hand brake to neutral the cam spreads the shoes but only to a position which is just short of touching the drum.
When you pull the lever back further the shoes clamp the drum preventing it from turning.
If you want more leverage on the hand brake or there is only enough room when the cam is flat you can install a clevis yoke with a slot in it and set it so the clevis pin only begins to touch the yoke when in neutral and movement back beyond that point and the cam will spread the shoes.
