regarding ABS braking sys, from my understanding: it wont activate under panic braking. it will lock deadly if u press ur brakes in a sudden. my friend told me from his experience with ford ranger ABS and isuzu dmax ABS.

lol, like that oso u notice ar?

Anyways, if I understand correctly, the whole point of ABS is to allow users to brake quickly without the wheels locking. When a car has ABS, you cannot pump the brakes like you would on a non ABS car. This would negate the ABS. You're supposed to just depress the brake fully without letting go.

Did your friend try turning the wheels when he was braking hard?

Wheel slipping I assume means locking of wheels? Well, this mostly happens when you brake quickly, mar.

When you pump your brakes, you're actually reducing the ABS' efficiency.
ABS is meant to stop wheel lock, not stop sliding. It just so happens stopping wheel lock reduces sliding in most road situations. That's all.

I'm sure your friend has a good reason for telling you this. Maybe it's due to him being offroad all the time. The quote above explains that ABS actually increases stopping distance in offroad situations.
