Brake Rotors

I have no clue how to find out what kind of brake system I have ? Anti lock or not ? its a 93 s10 2.8 ext cab 5spd. I need to know so I can get new rotors ASAP.

I believe that you don't have ABS on your '93. I have a Hayne manuel for '94-'04. I think that '94 was the first year that the S-10 had ABS. Look at your brake system under your hood. If you have ABS then you should have extra componets that the brake lines run through before going back to each wheel cylinder.
