Mystery of the smoking nuts
Got a car that had strip of deep wear in rear driver drum. Recently replaced both rear drums, shoes, and spring sets only to have it start smoking on me.
3 days back, took it to a brake shop and they said nothing looked wrong, they went over all 4 brakes, adjusted, and bled. For the green light to drive and they felt good.
Got hot yesterday. Took apart hub and checked the bearings and they seem good. Backed off the brakes a good amount. Still getting a weird rub
Drove it today, the more I drove the more I felt them start drag. Pulled over and measured the temp of the lugnuts and bearing hubs. 291 degrees on BOTH rear sides. Front brakes a cool 110.
Driver side rear wheel free spins for half a rotation and then drags (almost needs two hands to turn) for half a rotation. I think the new shoes/drum are also trying to wear a line in the same spot as the old ones. I can’t for the life of me see anything warped and can’t see any obvious rub spots on the shoes. Been through at least 2 brake shops and countless car folks and nobody had any ideas.
Help! What do I possibly look at next?
-wheel bearings seem pretty good. Even if one was bad would it heat up both sides?
-any common reasons for a gouge like the one in the photo? Hard to tell but it’s pretty deep.
-included a photo of my brake shoe set up. Does that little gap on the left of the pin tell me anything? I can’t get it to sit any more flush than that. The only spring I can’t find a replacement for is the one attached to the bar going to the ebrake, couldn’t that be messing things up this bad?
-is it possible that the back plate or hub is warped and causing this? Why are both my back hub assemblies so hot?
I feel like this this has its back wheels up in the air more than on the ground these days.
