Re: IML: Re-installing brake drums on '62

[randalpark@xxxxxxx]

Remember, these cars were built years ago when folks did it exactly 
like you said "as a matter of course". This step is necessary in order 
for Center Plane Brakes (aka Total Contact) to function at full 
capacity. If not, the "floating shoes" will not center properly on the 
inner drum surface, concentrating the stopping power in only portions 
of the shoes that have the most contact with the drums.

After I do a brake job, I run the car a few miles and then have them 
arced again. People who were use to working on these systems knew how 
to make them work correctly. Others write them off as never having been 
any good in the first place. In my driving career spanning over 
2,700,000 miles in both types of cars, I don't find the performance of 
the original systems lacking, but they do require (what is considered 
these days as) special knowledge and frequent adjustment.

heard or done that for years. Used to be a thing that you did as a 
matter of
course. I have wwworked as a mechanic off and on for years. Even used 
to
bond shoes to the metal . Don'g know if any one even does that anymore 
or if
anyone around here had a way to arc shoes. They really need to make 
sure that
the wheel cyclinder rods are fully in the wheel cyclinder. Make sure 
that
springs are on correct. And not hanging up on anything.
