Question about 2004 Chevrolet TrailBlazer
Had front brakes and rotors replaced and the light comes on sporadically. What do I need to do to reset system?
It doesn't need a reset, a mechanic needs to scan for the fault code that is setting the warning light. It could be a poor or no connection at the wheel speed sensor or a problem with the ABS.

I have had this same problem on two difference vehicles both of which are suburbans.
The solution is simple.
Remove the engine cover.
Locate a small ground wire that is bolted to the top rear of the engine block on the passenger side.
Remove the bolt, clean surfaces and replace.
This should solve your problem.
I know it seems too easy but it works.

Check ABS system for codes. I have an '03 Silverado and have a faulty EBCM( Electronic Brake Control Module, "ABS module"). Can't reset anything. Only replacement of EBCM will fix it. Incidentally, if you have to replace it, you can check on Ebay for a rebuilt unit. You shouldn't have an issue with your "base" braking system though, if this is the case. ABS is electronically controlled and with or without it, your brakes will still function. I hope this helps.

It seems now a days that everyone loves to turn rotors, the only reason to turn a rotor is if it is running out, what this means is that
it is moving back and forth and not in a straight line. What a brake tec is suppose to do is place a dial caliper on the rotor and spin it and see if it is running out,if it is then it must be turned,as long as the rotor is not under the mfg min width. Any vibration,pulsing,shudder,
would tell me that it needs to be turned, just wanted to explain the reason behind it. Any other questions please post back as everyone is more than happy to help.

check the connections on the abs, behind the rotor by strut is the connection for the abs if the connector is loose or not properly affixed to the clip it sets off the abs trouble code or low speed saftey usually activates at slow speed under 5 miles an hour the connector and clip are part of the abs circuit--also recheck ur brake pads for binding and brake fluid level --if u get a trouble code have vehicle scanned some auo stores such as auto zone / advanced auto scan for free this will tell u which sensor or unit is causing problem

on the rotors you probably noticed two lines one for the brakes and the other is your traction control magnet which picks up a signal to tell the computer to control the braking system when the wheel locks up in hard braking, you either damaged the magnet or it picked up some metal shaving while replacing the brake pads
