Front Brake Hub and Drum Lathe

Pictured below is a front hub mounted facing inward on my Van Norman brake drum lathe. It is center mounted on collets in the hub bearing races.

In this position a cut can be made across the drum mounting flange surface to determine any warpage or damage that may have occurred during removal of the old drum from the hub.

Be Careful!
A Word About Stud and Drum Removal!
Do not use a press or hammer to force the old wheel studs out of the hub and drum assembly.

Using brute force to overcome the swaged stud shoulder will almost always distort the hub and drum mounting flange, and will ruin an otherwise good hub.
Old studs and drums should be carefully removed from hubs by machining away the swaged shoulder of the wheel studs so that the studs will come out of the drum and hub easily and with little force.

See the links below for a swage cutter supplier, as well as the stud removal and installation page.

A light careful cut can be used to highlight the distortion, and to partially true up the surface so that new cast iron drums can be swaged to the used hubs.

These pics show a pair of hubs which have had a little material removed from the flange to true up the mounting surface so that new cast iron drums will run true.

After stud swaging, the brake lining surface of the hub and drum assembly can then be lightly trued to ensure that it also runs true.
