hydraulic handbrake ?

[Big Vern]

As TT says the parking brake on any road vehicle is required to be a mechanical device acting on either the front or rear wheels.
The hydraulic hand brake - a favourite of the rally boys - is not legal for road use which is why we used to build them with a flyoff hydraulic hand brake but keep the original vehicle system in tact as well.

Make's a bit of a mockery of it all when manufacturers fit EPB systems that fail in the on position, Audi/VW Seat Skoda.

You gotta love the early Citroen breaking systems Paul

Oh the joys of the front parking brake & the pump driven hydraulic service brakes ..... Engine fails & once the reserve pressure has gone, brakes no worky very well

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.

As stated above, both IVA and MOT require a mechanical 'parking' brake, independant of the 'service' brakes
