Re: Squealing Brake

Hi Rebus:

Those old brake drums need oversized linings.

Thus, you need to take/send the shoes and drums to a place like Fort Wayne Brake and Clutch to have linings cut to match.

That probably is not what is causing the squeal however. In fact squeal is still not very well understood. They just guess at what they think will not squeal and test it.

I knew a MOBIL engineer who said filing a chamfer on the edges of the shoe would get rid of squeal. He did it on his Packards in the 50's. Also some of those drums have srings on the to reduce squeal. If yours had them and they are gone that may cause a problem. They may also be squealing because old shoe material imbedded in the drum is transferring to the new shoes and causing a glaze.

Hope this helps.
