ABS.... is this normal?

Im used to driving a non abs car in the past along with newer model cars with abs. My question is this.. my cobra the abs seems to lock up too early. , example being lets say with a non abs car u can threshold break till the tires lock up. with most other newer cars i can break till aprox 15-20% of the threshold before the abs comes on and with the cobra it seems to lock up 30-40% of the threshold. Im talking driving on dry cement here. it makes me not even want to break moderatly hard due t the fact i dont want to chance the abs coming on. is this tipical of 94-95 mustangs or do i have an issue i need to look into. Im thinking something is wrong with the picture. Brian

goodyear gs-c 255-45-zr17's @32 psi all around. 70% tread left on the tires.28k on the car and suspension is ok . no worn or broken parts when i had it up in the air last week. and the brake pads are 70% front and 80% rear..

i mean that i can hear the abs modulating , i havnt had it happen yet driving fast enough to tell only like 30 40mph and i didnt stick my head out to see if it was locking and unlocking. i didnt hear skidding but i did feel and hear the abs module being activated .I would say that it is locking up though but seems like with not such a drastic deceleration to cause small skids. Im not just stabing the breaks ether. im slowly getting into them and going to slightly above moderate braking forces when it does this . not sure if all that made sence or not...lol
