i am buying a 93 chevy 1500 z71 soon and the brake light comes on once in a while and i'm told its the anti skid thingy. what is the anti skid thing exactly so i know what to order? thanks in advance?

 

It is skidding. In your Chevy, on the back of the wheel hub are the wires for the ABS system. The ABS sensor sits on the wheel bearing and hub assembly, and looks like a small rectangular box. Check to make sure all wires are connected and are not damaged. Then, turn the ignition key to the "II" position and check the ABS light. The dash lights will light up initially and should then go out after a few seconds. If the ABS light stays on, then the ABS system has failed. Because the ABS system is secured to the wheel bearings, both units must be changed by a professional mechanic.

 

ok. so i have to replace what exactly?

 

Nevermind. Just woke up then and didn't understand. Now I do.
