Hey guys, I just bought a 2004 trailblazer LS and when it driving it home from the dealership the brakes seemed to progressively lock up. They were fine until I drove for about 10 minutes, then they started to brake by themselves. Any ideas on what could cause this? I think air in the lines, but would love some other input. Thanks.

(I know this may be too model specific for the general thread, but the trailblazer thread seemed dead, so posted here as well. Mods feel free to take down if too model specific)

 

I think more than likely it would be a stuck caliper.

Even if they're fine when I first start off?

 

Is it pulling without or with braking, and to any side specific?

 

It seemed to do it even if I barely used my brakes. And I didn't seem to notice pulling to one side more than the other.

I'd also like to add that I think the car sat at the dealership for a while before I bought it.
