Dear All,

I was quite proud of myself for getting the brakes back on my 733. Unfortunately, I now can't get the drums on! The brake shoes I installed I got from e-bay, freshly re-lined. It would appear that the lining is too think. No amount of monkeying with the adjustment cam or support posts will allow the drums to slide on.

So, I am going to reinstall the old shoes, which are obviously worn but have enough material left to go several thousand miles (assuming I am not driving in the mountains). I would then like to get the spare shoes re-lined to the correct thickness. Anybody have a spec on that. I can find nothing in my reference materials.

The lining lengths, widths and thickness is given in the Packard Standard Sizes and Specifications sheet. It gives 3/16" thickness for all 7th thru 9th series.

Do brake shops still do "arcing" or "fit to drum" grinding or is that something else that EPA has now declared illegal.

When I had a brake job done on a Pacific several years ago, they measured the drum ID, set the machine then ground the shoes to proper arc. If that service is still available maybe they could do the same to your excess.

My local brake shop still arc-grinds the linings to the drum diameter as long as the lining is non-asbestos.

Thanks for the info. I keep forgetting to check the standard specifications section! Sorry.

The 'new' shoes have a thickness of .23, well above the 3/16 (.1875).

I got the old shoes cleaned up and put them on. The drums fit now.

Thanks tons,

Tom

Tough break on the brakes, Tom.
