Re: '39 Model 110 brake drum max. inside diameter?

I recall that in the day of exclusive drum brake use it was common practice to get replacement brake shoes with oversize (thicker) lining. The drums would be turned, and then the inside diameter measured. This measurement would be transferred to the linings on the shoes, via a special gauge, and the linings would be sized to reflect the drum diameter. Also, particular attention was paid to the lining material on the primary (front) and secondary (rear) shoes. The primary and secondary lining materials were different. This involved special tools and knowledge that are probably in the waste bin of brake shop practice now. Keep in mind the special brake adjustment procedure on Packards. I always thought the brakes on these cars were more than adequate for the job, and feel completely comfortable driving my 115C in traffic or on the road. Good luck, John
