    How about the emergency brake adjustment? You should back that off as needed also.

    Arching the shoes will solve your problem.............

    I know there is a difference on rear shoes between the disc brake cars and the all-drum brake cars, I don't know if it's possible to install the drum style shoes on disc equipped cars, but might be something to look at. In the "old days", brake shoes were made oversized and then ground, or arced, to the exact diameter of the drum by grinding them to fit. Some places will still do that, but that process pretty much went away when it was discovered that asbestos dust was bad.

    I was trying to think how a lip could have anything to do with the drum not passing over the shoes ?

    Were the drums turned?
    Are the linings oversized?
    Are the wheel cylinders completely compressed?

    Drums were turned, but just a cleanup pass. No ridge on the turned surface that I can see. The replacement brake shoes came directly from SI - they don't show as having oversized linings in their catalog. Don't know if the cylinders are completely compressed, but the shoes are pushed together as far as the strut between them at the top of the backing plate will allow.

    63 Avanti Rear Brake Drums - what gives?

    Just finishing up a complete rebuild of the rear brakes, including new wheel cylinders, grease seals and brake shoes, all from SI. Thought I'd slide the hubs and drums back on just to get them out of the way while I installed the new ss brake lines. However, the drums won't fit over the new brake shoes! Neither axle. And yes, the eccentrics are backed off all the way.

    Anyone else ever had this problem? And more to the point - now what???
