Keeping this as first hand experience of my navigator :), complete brake system has been upgraded to Power assisted brakes, powered by a pump from Merc 300 D & a cylinder & booster from a brand I cant write here :), brake wheel cylinder, all brake lines both rubber and steel changed!
So now they Say you just have to say Stop & wheels will be locked :), old manual ABS system removed 
Operation Darkness (old cylinder removed)

New one is ready

& Installed!

It wasn't that simple, it involved a research of 1.5 year, a first hand experiment on DeeMog and its test in the North and then technology transfer to BeeMog!
