As I approach a stop sign and apply brakes it feels as if my ABS is trying to activate. (Dry road) This symtom just started. Last month the car passed state inspection so I don't suppose it is a major brake problem. What do you think it is??

I think you have a wheel speed sensor dropping out at low speed but you need a scan tool to figure out which one.There may or may not be a code stored so sensor data needs to be monitored.

Yup, I just did one on a Venture van yesterday. Once the van slowed to 7 mph with my foot on the brake, the left front sensor would drop out and cause the ABS to kick in.

Thank you for the replies. I'm not an automotive technician so I do my best to describe the problem. The car comes to somewhat of a "choppy" stop instead of smooth stop. Do you still think it's an ABS problem? Also, does this sort of thing just happen without a warning? It passed state inspection less than a month ago.

Yes, this will just happen with no warning. Do as Davo suggested and have a technician road test your vehicle with a scan tool to monitor wheel speed data as vehicle is brought to a stop. That data will indicate which sensor is faulty.

Do you feel a brief flutter in the brake pedal before the car is stopped?

Yes, that is exactly what happens. A brief flutter occurs in the brake pedal before the car stops. I plan to take it to our Chevy Dealer next week. The car is only 2 years old. I hope the repair willbe covered under our extended warranty.
