120Y's have the exact rear slave cylinders as 1000's. (My 1000 diff has 120Y slaves in it now)
A 120Y front disc and master Cylinder should work out perfect.

Sorry I misread your post, mikey.
Looks like you need to see the brake guys to see which master cyl to use.

I got new slaves for the rear about two weeks ago.
1000's 1200's and 120y's share rear slaves, I wouldn't be suprised if that list was shared with other models.
 
I will bring that master cyl and front disc set up with me on fri, it should have you all sorted out brake wise.
I think I have 1200 discs in the garrage as well. either way we should both be able do do disc conversions with what's there.

Nuh I dont know him, I've met the boss only but I cant remember his name, top bloke I think, he openned the shop late on a saturday cause I had to drop off a morris minor m/cyl and some wheel cyl for them to sleave and kit. I was really happy with them and the price was bloody good. I havent touched my m/cyl yet, I'm just finishing off my body work then I'll get back onto my brakes. I want a duel m/cyl just for safety but I want to find the right one for the size of the brakes. I had a look at the photo's i've got and I've got a photo of the disc I think, but the caliper is really tricky, the split pin design is something toyotas use but I'll keep looking. The hub looks definately like a 120y/1200 coupe hub, it doesnt look like a stanza cause they have a small space for where the disc bolts onto the hub. I'll keep looking for you. Cheers
 

ha ha yeah its a pain in the arse when the ppl before you didnt have a clue what their from, That was the same on my morrie minor, ended up finding that they used Fiat Discs and Calipers, ha I was stumped.

finally found the info you guys might be interested in for the Pinnie front end
 
Please note heavier Renault 12 if you look up the DBA catalogue I think had 
thinner solid discs and the car weighed more than a 1000.
So the pinnie rear discs should be more than adequate...

Oh yes its all in and done! I re drilled 3 of the 4 holes in the caliper braket, slid the disk over the hub bolted on the vs rear caliper, got brake hoses made up with a fitting for the commo caliper at one end and the 1000 brake lines at the other, used a 1200 duel resivour disk master cylinder, blocked off the rear line outlet on the firewall mounted splitter so it split the pressure to the front brakes only, made an extention line from the rear fitting on the master cylinder directly to the rear line and hey presto! been driving on it for a few weeks   If you want pics or and more info give us a yell -- Jake

decided that this ute will be getting a quick do over (re-paint and removing any rust) and be used as my daily/work car. so will be sticking with the a12 with the single weber, will be just low with wide wheels and half decent paint job. also will be used to test my shock setups
 
the second ute i own (the better of the 2) will be getting the g13b turbo heart transplant and i'll be aiming for 300rwhp or more
