ABS engaged at low speed and light braking

Hi, my toyota 99 RAV4 had its ABS engaged at low speed when braking slightly. I’ve had it checked out at a local repair shop, they didn’t find an obvious problem with the ABS. I wonder if this is going to be dangerous, for now it’s mainly annoying~

Probably just annoying. ABS systems usually show signs of failure on older vehicles. You need to have the system checked out by a mechanic that’s familiar with ABS. Do you have an ABS light on? How does the system work at higher speeds?
