After successfully upgrading to disc brakes on the front of my 59 Bugeye and replacing the MC with a 3/4" unit, I decided to go all the way and upgrade the rear drums to the later dual piston cylinder type. I bought all the parts from a later model Midget - backing plates, springs, e-brake links, and ordered new shoes, new cylinders, etc. Even bought new wheel bearing kits too.
I had the drums machined to remove 1/16" off the edge so they wouldn't rub against the backing plates. Did the changeover, but now the original hubs are rubbing against the backing plates! I tried grinding down the shield a little and it seemed to help, but didn't want to go too far so it still rubs. I'm still running with the original Bugeye axles and hubs, so I'm beginning to wonder if the axles on the later midgets are maybe 1/16" longer, or maybe the differential housing is a little narrower, or if the hubs are a bit different
Has anyone else had this problem? Is there a common preferred solution?
