Yea, sounds like ABS. I know people say ABS can read the sensors faster than we can but the brake pads can only move so fast. I've also found every one I've ever driven to be way too sensitive, it will engage way too soon. I tested out one time by braking in an empty parking lot with and without ABS (pulling the fuse) and I could beat ABS every time and I don't have the best of reflexes. This was a year 2000 truck with three channel ABS so both rear wheels shared a sensor.
I still prefer the poor mans ABS where you have a true 4x4 with lever shift and to lock the front and back and a manual transmission, basically a wheel on one end can't stop spinning to skid because a wheel on the other end as well as the engine is still turning thereby forcing the wheel that might have skidded to keep turning. I was driving home late one night from work when I went up the raised roadway over the highway and saw the police directing traffic and stopping cars getting on and off the highway because the ones coming over the hill were going through the intersection, sliding or ABS preventing them from stopping. The police saw me coming and stopped traffic then I just down shifted through the gears, got in the left turn lane and slowed down pushed the clutch and braked the last second to a stop. I think the policeman smiled as he waved me through the left turn as the cars in the straight lanes beside skidded on through the intersection.
