So think I read here some where that the studs where not drilled right from the factory on after market hub. My front brake shoe's scrub in one place. Had the drum's turned and they where not perfect and not round. So now think it must be a hub problem. The wheel turn's free till one point then get's tight in the brake shoe. Both side's are doing this. Have violent shaking in the front when braking. Been a mechanic for a long time and just frustrated with this after market junk we get. Guess these are bug's we have to work out. Any one know if this could be true let me know. Got the hub's from Summit racing. Blue.
