As far as I know , a hydraulic handbrake wont pass SVA/IVA or MOT , as the handbrake has to be a separate mechanical brake ?
Its cuz I is blond , innit

You need to have a mecanical handbrake aswell.

From my understanding of the way the law is currently being interpreted the mechanical handbrake has to worked by the same lever.

I got the impression that you can legally have a hydraulic handbrake but the system has to be completely separate to the brakes.
I assume that means you would need separate callipers for the handbrake etc
I could be wrong tho

Hijacking this post a bit and Playing devels advocate (going back to a setup we had on a road legal ? racer ).
Lets say we have
Mechanical ( ratchet handbrake ) operating it own Master Cylinder (and resvior) running through independant brake lines and second set of calipers
Should it pass an MOT ?
I would say yes ( as we got it through that the parking break system was indipendant foot breaking system ) but the didnt like that it was hydralic
saying it could leak fluid loose presure - So we pointed out the a cable could streach / break and they finally aggreed to give us a ticket after
much flicking throught the MOT book ( well over 10 years ago BTW ).
discuss ?

Your wrong ---- with good reason the parking brake has to be mechanical in operation although the initial actuation can be by other means (eg
usually electrical), everything that keeps the brakes applied to the disc or drum has to be purely mechanical. Hydraulic systems leak & hot fluid
contracts so hydraulics cannot provide a reliable handbrake for overnight parking.

I cannot help you with the selection of calipers and can only pass on my experience.
On the Trials car I'm running a hydraulic handbrake which I made myself using a Girling master cylinder as shown in the photograph. The port on
this master cylinder that normally goes to the remote reservoir is connected instead to the rear brake pipe from the main master cylinder. The other
port takes the pipe to the rear brakes. I'm using Citroen AX calipers and this set up works fine.
I hope this goes a small way to helping.

I have seen system before on works Escorts and it scares the pants off me --- too much chance of things going wrong.
Also as it constitues a means of altering the brake effort distribution of the service I am pretty sure it is an SVA fail if not downright illegal.

Then you don't need any kind of handbrake.

Pretty much every tarmac rally car I have ever seen has used the same system, it can't be that unreliable.
