The datsun mc has a residual valve in each circuit, this is held in by the large nut which the brake lines screws into. I removed the valve from the front circuit. It is meant to maintain a bit of line pressure for drum brake systems. I think my mc was a datsun sunny 11/16 unit.

Has anyone thought of using a remote booster?? Vh40 or 44, as IF your doing major mods for an engineer's certificate you need to maintain the booster..

The PBR boosters do seem very popular. about $450 new but from the comments I've seen they're very simple to install. I read that the VH40 is for disc/drum and the VH44 is for drum/drum. Can anyone add to this?

Hi Guys,
 
I am in the midst of fitting the volvo calipers with Capri struts and the 120Y m/c.
 
I had a friend make up the firewall adapter out of aircraft grade aluminium.  I think it looks realy sexy and is light as.
 
The next step is to make the pushrod adjustable to ensure everything matches up perfect.
 
I can post up some measurements if you want.
 
Cheers,
 
Matt

Yeah i have been told the same thing...i'm thinking just get rid of it use an adjustable pedal box box and see if the engineer questions it...

Being Qld I think booster has to stay. But depending on the engineer I spose, they always slip around the regulations

removed...that idea wouldn't have worked...

It seems like the VH44  for drums and VH40 for discs....there seem to be a multitude of suffixes however meaning different variants which will work for different applications however.. I haven't seen what their boosting ratios are though.
 
 

Finally got this installed last weekend.
 
Here's a few pics
