: Rebuilding the brakes on my late 30 coupe. Two questions
: 1)Local brake specialists told me that they could turn out the drums and still have adequate material to be safe. The turning left a little ridge at the hub side edge of the braking surface.Do the shoes go all of the way out to the edge? If not, how far away from the inside edge of the drum can the ledge be, without hitting the lining?
: 2) Brattons advertizes front brake operating pin shims. With the pins and operating wedges installed, and manually moving the operating arm to the fully applied position, the wedge is also just at the fully extended position. Is this adequate, or do I need to use the shims?

Ken,
Wear patterns indicate that the shoes get fairly close to the hub edje.I don't think a ridge of 1/8" would be noticed, but any more might be a little problem until the shoes are worn in.
It's good to have some operating pin shims on hand.The operating levers that the brake rods attach to should lean forward approximately 25 degrees when the brakes are adjusted, for proper leverage.If your drums are oversized and the shoes are not the lever will need to be pulled back with the brake rod adjustment a little more than normal.Be sure the lever is around 30 degrees forward with the shoes retracted and it should be enough.
