MK1 granny brake master cylinder

Having real problems with the MK1 at the moment. It is leaking brake fluid between the master cylinder & servo. Took the master cylinder off & it's obviously leaking fluid through the rear seal 
The problem is finding a seal replacement kit. There are none on Ebay & I can't seem to find anywhere that does them.
Can anyone help ? 
P.S...it's a Girling

JC.
Snoopy's first suggestion Big Redd are quite remarkable,even Ford have stopped doing cylinder kits,but Big Redd will supply.I wanted dust boots for the other half's Peugeot because one was split,Peugeot man said caliper only mate,but not Big Redd !

Thanks for that Dave, although the kit they are doing is for an ATE cylinder I'll Email them to see if they have one for a Girling
P.S...didn't know that the MK2 granny & 2.8 Capri shared the same cylinder. If a Girling kit is gonna prove difficult to find, then I suppose I could actually fit an ATE cylinder on it, if I can find one

JC, I had this problem on a Mk2 Granada - fluid level kept dropping, kept putting fluid in...but no sign of a leak !
Is the Mk2 master cylinder the same as a Mk1 ?
Ebay item number: 280332373038 - Mk2 2.8i being broken.
May be worth investigating ?

Mike.
It usually goes up the vacuum pipe and is consumed by the engine !

That's also where the ATF goes when the diaphragm in that bit ( sorry can't remember what it's called  ) which fits on the side of the autobox fails 
Luckily caught it in time but I was told the engine can literally 'suck' all the ATF out of the gearbox in less than 100 miles.

Thanks for that Scorpio Mike, I've written him an email to see if it is a Girling cylinder or not

Thanks Snoopy, 'Big Redd' actually do a Girling 3.0 seal kit & thanks -Mike-, 'Popys Oldshop' actually do a Girling 3.0 seal kit as well which is cheaper than 'Big Redd'
Unfortunately, this post may have been in vain  .....
After stripping down the master cylinder, I saw that there is about 5mm of rust going inwards into the cylinder shaft, which is probably why the rear primary piston lip-seal is leaking. Being that you can't actually buy (for love nor money) a new master cylinder for the MK1 anymore, then it looks like I'm gonna have to get it refurbished
I wonder how much that will cost ?

Jon, I did a search on Google for MK 1 Granada Master Cylinder and there are a number of sites but at least two talk about using one from a 2.8 with modifications such as sealing a 'third' pipe with a brake nipple. May help to have a look.  Mike.

JC, these guys might be worth trying : http://www.brakeparts.co.uk/index.html
Master cylinder ( Girling ) P/N BMC4380 @ £124.57
They also list a service kit P/N BMS1024 @ £14.73
Hope they are the right ones.
