I have a 98 Chevy I bought last Sept. It had 43k miles and I did a front end brake job just to be safe. The pads weren't wore out but replaced them anyway. Now, every time I come to a stop at the last second it seems one of the tires lock or something. It grabs real hard and skips a little. Do you think maybe the drums on the rear are wore out? I repacked the spindles last year when I did the front but checked and there isn't any grease on the rotors. Thanks for the help.<p>Adam <p>Oh, it is a c3500 single, no duals!
