Nice to see you back Ronnie,as for citroen brake and hydraulic system's you are talking to the man who served his time in a dealers 71 to 80 so they hold no fear to me.
I used to PDI new D series then the CX and Gs BX etc.
My comment was aimed at VAG products as they fail locked on due to failure of the switch,there is nothing in the owners manual to tell you how to deal with it other than call the stealers (yes stealers !)it is possible to unplug the connections and reverse the polarity to wind them off.

Back to the handbrake saga it does stipulate for mot requirements that the handbrake mechanism is mechanical,so fit another system later if you have to.

Finally (yes honestly) the Citroen system and its derivatives fitted to Rollers and the like have a pressure accumalator fitted as standard under the pressure regulator that should give a reserve of pressure and this is also part of the MOT test.

Just re-read your post Ron,the early ones had a ramp arrangement for load sensing and they were violent.
