Periodic brake pedal pulsing

Periodic brake peddle pulsing at very slow speeds.

Periodically I am getting brake peddle pulsing on applying brakes at very slow speeds as with AWB sensing a slippery surface. Following a brake inspection with an approved facility where they removed rear wheels and checked brakes. Replaced disc pads and rotors on front axle as they were warped and repacked seals.
During a test drive, the maintenance supervisor found similar conditions still existed. Although there are no safety issues and there are no system fault lights or indicators, we are perplexed. A theory that there may be some kind of sensor acting up, is all that remains to explore.

Anyone with similar experience.

Maybe they put on warped rotors. That has caused me similar pedal pulsing.

Do you have a Ford or Workhorse Chassis ?

It is a Workhorse Cliff.

I'll move this thread there to try and get you some answers.

Two issues with Workhorse chassis.. First the sensors get dirty and need to be cleaned, this basically disables the ABS will not cause the pulsing you cite

Second, Rotor cracks are fairly common.. This CAN cause pulsing.

If you have reaosn to think it is the ABS system doing it, I would not worry too much. but do keep looking into it.. Sorry I can not give you an easy fix.
