Answer 2

Just like it says in your owners manual - you have a problem with your Anti-Lock Brake System.  It can really be one of only 5 things (one or more of the 4 Wheel Speed Sensors or the ABS Module itself).  Any half-way decent shop can diagnose the problem.  Until it is diagnosed and repaired the ABS system will not function.  Be careful too as on some GM models of this vintage the regular rear brakes are deactivated when there is a ABS fault which means you lose about 20% of your regular stopping ability.

Answer 3

Problem with the ABS system. Take it to a GM dealership.

Answer 4

could be brakes are uneven in the rear a speed sensor or even a brake light out
