I've owned the van for about 1.5 years.
Problem #1: When it's cold out, sometimes when hitting the brakes (no matter how lightly), the right rear brake slams on with full force. This doesn't happen during the summer. The frequency of this happening has increased over the time I've owned the van.

Problem #2: At higher speeds (50+ mph), there is sometimes a scraping noise coming from the right rear wheel. It comes and goes. There will be no weird sounds and then I enter a curve and the scraping is there. The volume of the scraping varies. The scraping noise may or may not go away when I exit the curve.
I had the wheels looked at 3 months ago due to some tire noise, and the wheel bearings were loose. I had them tightened and the tire noise has become normal.
Well i can help with problem #2
even if you tightened the wheel bearing, it is probably worn out..
what it does when it's loose is you won't hear much noise when you drive on a strait road but the minute you put some weight on it, like when you take a curve, the weight of the body is applied on the bearing resulting in a scraping noise....
and the faster you'll drive the more noise you'll get
so let's say you take a left turn you're gonna hear noise from the right wheel...

It was indeed the wheel bearing. The dust cap had come off, and the bearing had been fused to the brake drum somehow. The mechanics spent 20 minutes trying to separate them but were unsuccessful. Hopefully this will also fix the braking problem - thanks for your insight!
