Only Use Stab Braking On Systems Without ABS?

I'm a bit confused with a statement made in the High Road. I don't see the same statement being made in my PA Commercial Driver's Manual. Here's the statement:

Stab Braking: Use only on vehicles without anti-lock systems.

Stab breaking is considered an emergency breaking method, correct? Then is it only an emergency braking method to be used on just vehicles without ABS? Is controlled breaking the only emergency method to be used on a vehicle with ABS? The manual says to break as you normally would in a vehicle equipped w/ ABS, so I'm assuming it's not referring to an emergency breaking method? Ugh - confusion. I'm sure it's simple in practice, but my head's turned upside down.

It's my understanding that you would use the stab method if the ABS system has failed otherwise you would use the controlled braking method and let the ABS system work as designed ! would be interested to what the experts say here ??

I wonder if something just 'clicked.' Controlled braking is when CONSTANT pressure is applied on the brake pedal, unless if your wheels happen to lock up (even with ABS), during which you obviously release the brakes until the the wheels start moving again, then you can reapply.

Stab breaking is DELIBERATE INTERMITTENT pressure applied on the brake pedal, in the form of 'stabbing,' which is used on vehicles without ABS because you wheels WILL lock up since there's no ABS.

Vehicles with or without ABS can still lock up, depending on how hard the breaks are applied, conditions on the road, or in the case of ABS, mechanical failure. ABS acts as an automatic stabbing affect even when you apply constant pressure on the brake pedal, as in controlled breaking. But again, press hard enough and under certain conditions, even with controlled breaking on a vehicle w/ ABS, and you can still have wheels that lock up.

It's my understanding that you would use the stab method if the ABS system has failed otherwise you would use the controlled braking method and let the ABS system work as designed ! would be interested to what the experts say here ??

I was typing as you responded. I think we're thinking the same thing.
