98 Grand Am ABS ????

Sounds like you need to get it into a shop asap!
Thats not safe stopping the way it does.

Could be several things, but you wont know untill its been scanned with the right scan tool. One that reads all ABS errors, specificly the GM tech II which can do many things no other scanner can do for your GM car.

Hope that helped and Welcome to AF!
