Cavalier Brake Master Cylinder

As someone who's not real mechanically inclined, I' need help changing the master cylinder on a 1994 Cavalier with ABS brakes. I've got the new master cylinder but don't want to do more damage than good removing the old one. I can't figure out how to get the booster off the master cylinder. Any help would be appreciated.

Do you mean the brake booster or the ABS module? The master cylinder is just held on by two nuts, can't say for sure how the ABS module is held on, never looked at any that closely.
