I have a 94 2500, was wondering what the most common problem, for the front brakes to pull alot, it pulls to the drivers side. Thanks

 

check to make sure the caliper on the opposing side is working and sliding correctly. while your there check pads. if that is all fine check the rears for the same good movement and good pads. Any noises or grinding?

 

As bj said, check the rears. The self adjusters are notorious for not working.
If you have a 4wd check the trackbar for play.

 

thanks guys, will check it out this weekend.
