Does anyone know a good source for brake shoes for a 46 Desoto sedan? The ones I got from ebay are a tad to big for the drums to fit on even with them adjusted in all the way?

John,

The shoes you have are likely correct. Your brake shoes may need to be arced to the drum. Do a Google search for "arcing drum brakes" and you will find both posts and video links on this topic. This link to a Plymouth forum may be most applicable: http://p15-d24.com/topic/36439-arcing-b ... -the-drum/

I had this same issue on my '55 sedan. Same basic brake set up as your '46. New shoes and adjustment cams all the way in and drums would not fit. Fortunately, a local AACA Region member used to own a brake shop and had the old machine which performs this task. He did the work and the drums fit like a glove.

Good luck. Let us know how things work out.

Mark

I have some original in the box linings with rivets if you are interested. The box says they fit all except 7 passenger sedan and limo. E-mail me at Telmardie3033@aol.com

I have a brake-shoe grinder if you can't find anybody local.

Would need the diameter of the brake drums measured with a micrometer.

Some folks may not be aware that the anchor lug itself is an adjustment cam. So loosen the nuts on the aft side of the backing plates and rotate the lugs with the arrows pointing toward each other.

Good Luck
Steve

I have been having brake problems with my 53 S16. The drums are roughly 12" inside dia. Is there a place to find the maximum ID these drums can be turned out to? The shop manual does not say. If there is no place, does anyone know? I know the shoes do not fit well in the drums. Thank you.

From school that was over 30 years ago, I seem to remember that .125" oversize was the max that a brake drum could safely be turned.

I did a quick online check, and read similar information regarding the maximum drum diameter, but they encouraged limiting the oversize dimension to .080" to provide .040" thickness on the drum for new wear.

I see forum comments that are discouraging having drums turned unless they absolutely need it. Many people can't simply buy new drums when the set they have can't be easily replaced someday by a trip to the parts store simply because they're not made.
