Having a brake problem? The entire brake system has been replace because had issues not been able to get a good friction on the brakes felt to spongy . I end up changing the ABS system . The truck brakes fine but one day and notice the antilock brakes were not working the truck slide sideway. I get ABS light, I check the abs error with Actron code scanner cp9001 GM & saturn. But notices its giving me alot of errors 28,12,37,36,6,7,8. will it be better to take to a specialist on ABS or is their something I can do since i have not replace the ABS cables that are next to the calipers.
