Have been thru this experience my self lately...

Had my beddy master cylinder resleeved a few years back....rubbers died the other day...

so i had it cleaned up at my local brake place with a new rubber kit put thru it

my mate at the brake place...confirmed that the beddy Mr/Cy is too small a capacity for my HQ disc setup

he has done a few legal NSW brake conversions w  XD XC Ford Mr/Cy and booster 

he said bout $700 for both..fitted new

Cords, funny I was at BrakePro yesterday on a similar issue. My Beddy has the large master cyclinder and the bonnet has a bubble cut into it to accommodate the edge of the master cylinder.
I am running HQ front discs and have a drum rear setup. The guy told me that a Ford XA, XB or XC booster and master can fit. You will have to change the screws to the brake lines.
BrakePro have quoted me about $500 to do the job.

Hope this helps.

i got a van here with a mazda 929 master.. one with hz master.. and one with the xc ford. use whatever you can get your hands on with a 1" bore for the front discs and setup for drums on the back.

cheers

Back in the day we used to use a torana LC booster with a ford XC master, the push rod was shortened and the holes on the master had to be filed out a tiny bit, this fitted well in the bonnet space without any bonnet modifications, worked a treat too. I dont know the length of the pushrod modification though but it was a matter of cut bigger then nibble bits off then round off to fit

This is an old post but just to provide some info for anyone else reading this. I have HQ discs on my LWB and a 9" diff running off the Bedford master cylinder with no problems. You don't need to change to another master cylinder but you do need to do a few mods.

I changed the 9" wheel cylinders to a smaller dia as the ones in there were huge and would lock up. Can't remember the new size but 3/4" bore rings a bell. The CF master cylinder I had re sleaved to 7/8" and that's it. All works a treat.

Hope this helps.
Garry.

Garry, you could of just run a brake bias instead of smaller clys in back. They were common in HQ and P76 etc
