if it gets that hot, you'll smell the pads burning. You don't have to drive 10 min, you sneak up on it. Drive it around the block, first. Then if it isn't locked up, drive another block, and so on until you're more confident in driving it further
I've driven it around the neighborhood a couple times, no hot wheels yet. It just feels like a stick initially when I press the brakes and they take a second to release. I dont hear any scraping or dragging brake pads though.
I also installed an 8 3/4 with higher gears and posi so it could be a combination of getting used to everything at the same time as well.
