One problem related to brake fluid leak has been reported for the 2000 Chevrolet S10. The most recently reported issues are listed below.
Driving normally, pressed the break pedal and it went to the floor; fortunately, I was close to home and no traffic that I managed to roll slowly home. Rusty break lines causing break fluid to leak by driver side door. Tried breaks again- totally not functional. Ironically read article about gm's problem with rusty break lines in their older model trucks. Making it a point to notify NHTSA that this problem affects s-10s as well as the bigger models. Conversations with friends indicate to me that this effects a lot of drivers. All gm truck owners should be alerted to problem. Under different conditions with higher speeds or traffic or pedestrians, this could have turned into a catastrophe.
