I ordered a master cylinder, will be here Friday. The dealership says my steering line is discontinued so I'm going to a hydraulics shop to manufacture a line for me.

Can my brake booster be bad? I have had my ABS light on and replaced my front wheel bearings and the light still remained on. I scanned the vehicle with a scanner that does ABS codes and no reading could be obtained for ABS, it said no information available. On my wife's 2003 Grand AM the ABS light was on and told me which wheel was causing the issue so I know the scanner works.
