I have a 1999 Silverado. I can be driving down the highway with the cruise on and the front brakes apply themselves without me doing anything. They don't lock up or anything but they drag enough that the truck downshifts to speed back up and when I let off the gas it slows down. Then 5 miles later they slowly let go and it works fine again. Ijacked it upand both wheels are hard to turn with my handsbecause the brakes are on.Any ideas outthere?

 

weird...just the fronts?..I've seen brake lite switches hang the pedal,but it'd be all 4..
maybe a master cyl..or an abs unit...it's gonna be tuff to diagnose

 

Yes just the fronts. I put new front brakes and rotors on yesterday and they are blue after 8 miles from getting hot.

 

weird..possible master cylinder...or an abs unit problem (hopefully not)
