AWD Overkill for Philly? Does it help in rain?

Well again you completely missed my point. Yes I know how an ABS system works. But pulsing in the ABS actuator does not equal pulsing at the brake surface. When you use the ABS, you feel pulsing in the pedal, but do you feel pulsing in the actual braking of the vehicle?

 

The reaction time in the brake fluid between the solenoid and the piston (including flexing in the rubber brake lines), the friction and rollback in the piston, the friction in the calipers as they slide over the pins all results in a smoothing of those pulses such that the actual torque reaction at the wheel is not a pulse, but a smooth, continues braking torque. That makes it very easy to create a reaction through the differential which shifts drive torque to the other side.

Why don't you read this Wikipedia page on ABS systems and you can always challenge the author:My link. It states that a ABS system can release/apply braking pressure up to 16 times per second.

Why don't you read Waldo's post again and try to comprehend it? Applying and releasing braking pressure doesn't result in a on/off binary braking action - it just keeps the braking friction right at the threshold of lockup but the vehicle doesn't "pulse" when slowing down - it slows down gradually and smoothly.

 

The whole point was the ABS system can be used to slow down (not stop completely) s spinning wheel thereby forcing torque to the non spinning wheel. That's the basis of all electronic traction control systems. It works.

Does it say that a piston can move in and out of a caliper 16 times per second?

It says what I stated.

 

If your trying to make the point that I said "pulsing the brakes" instead of "pulsing the brake pressure"? I did and that was incorrect.

So then what's your point? How is pulsing the brake pressure related to AWD and torque transfer?

Nothing at all. It was your Tag Team partner that was trying to explain a open differtential working with TC and I incorrectly stated that it pulsed the brakes which it doesn't.

 

Actually Ford thinks AWD means a 4WD with TC.
