Series 1 brake master cylinder

[moparrangie]

I picked up a series1 1956 short ute a week ago. Basically in great condition, just oil leaks from the engine sump, rocker cover and side plate. Now this thing drives great apart from lack of brakes. The master cylinder is shot so I ordered another one. It turned up today but is only 2 bolt flange not 3 bolt as what's on it. I can make the 2 bolt fit but that's going to take elongating the holes to change the PCD by 7mm.
Is this what most people have to do when changing master cylinders on the series 1s?
Also the adjustable link out of the master cylinder is a different thread but that's easy to change by just clipping the old one into the master cylinder.

The three hole master cylinders are still available for the 80" Minvera and can be made to fit the 86" by swapping over the pushrod.

I would sell the two bolt pattern one to someone with a 88" Series 2 and go to eBay in Belgian to pick up the three bolt one, the price of the one I brought wasn't too bad either.

Ah thanks for that. I will make the 2 bolt fit for now and hunt up a 3 bolt from over there

There is a 2-bolt conversion kit available from the UK (saves modifying the outrigger). I'll see if I can remember who the supplier was.

Found it http://www.dingocroft.co.uk/acatalog/Series1_Brakes-p3.html

I would get the old one stainless steel sleeved. Expensive, I know but you would basically never be looking for a new one again, just the seal kit when the time came.

Dan.
69 2A 88" pet4 (still in disguise), 68 2B FC pet6 (still resting quietly), plus 20 (no, not a misprint!) other parts/project cars (2xS2s, 7xS2As, 11xS3s). I think I may have gotten a bit carried away.....

[moparrangie]

The adaptor I made worked great. About 30 mins work cost 3 dollars haha. Will keep 3 bolt original to sleeve when I can be bothered. Being a machinist 5 days a week means I hate machining stuff in my own time

Just took delivery of a Minerva master cylinder (thanks Arthur).
I'll post pics in my 'Series I with PTO welder' thread when I get a moment.

I just pulled the leaking 1 drive old cylinder. Looks fine but how old was the rubber? Will hunt up a new rubber and give it a go. Had problems with the fuel tank. It was full
Of anti leak but it had basically all come adrift. Cleaned the anti leak out so will see how it goes

Well I'm sure I have found the reason of the fluid leak on the new master cylinder. Just poor machining of a length that helps seal the inner diameter of the cup seal. A length was about .2mm long, machined .4 off and now there is positive crush on the inner diameter and seal face. Hope all goes well when refitted
