like subject.....if its build inside the centre console arm rest....so you wont see anything...

is it allowed on a road car....?

 

The only issue over here in the UK is with the cables needed for a mechanical means of locking the wheel. It dosn't need to be hidden.

If you just rely on the hydraulics to hold it the pressure will drop after a short while and your car will roll off, if its parked on a hill.

If you can sort out the mechanical bit then its not a problem in the UK

 

technically no, you need a machanical form of holding the car stationary which means either a cable or the like

but on the other hand, some people at certain mot stations may not see that there is no cable arrangement and let you off with it

 

ok....thanks...
