But from what you were saying (about having to disengage and reapply anyway) it sounded like it would reduce the braking pressure going to the brakes to zero.

Did I misunderstand/am wrong/etc?
As far as I am aware (on my Kwak, the new, 3 times plus more expensive system some manufacturers are using may be different) the rider sets the input level, the ABS just backs that off to zero if a lock is detected then re-applies to the input level set - so if that is high enough to cause it to kick again, it would

Example

Lock point is 80%

Rider hits brakes at 100%, ABS kicks in, you get a braking up to 80%, then nothing, the system backs it off to 0% and has another go, if you are still applying > 80% it will hit that and go through the cycle again until the input is < 80%.

As I said the OP is from experience/reasoning, and I accept I may be wrong in some of my conjectures, and I am happy to have those errors pointed out.
