Can anyone help me with the following questions related with Brakes..I have a 2014 FFE. Also, if you can let me any links for Ford Focus Electric Workshop manual, that would be very much appreciated. Thanks very much.

1. Can the ABS module control control the brake booster and apply brakes? I know it can always go through the HCU...If so, when does it choose between going through the booster versus the HCU?

2. We did the following braking experiment with FFE 2014: The front wheels are spinning and are supported on a hydraulic bench. The rear wheels are on the ground and not moving. Traction control was on. We did not push the brake pedal at all. However, we send the brake signals through the angle sensor to the ABS control module....We were hoping that the front wheels would brake..but that did not happen even though the vacuum pump was working (the signals we sent were accepted). Can any one let me know why this is the case? Does the ABS module expect something else? (we havent yet done the experiment with the traction control off)
