Had a chance to pull out the brake booster and master to upgrade it and put in the proportioning valve.
Firstly, i found a good use for this set of crows foot flare nut spanners i picked up ages ago:

In combination with the impact ratchet they make short work of getting brake lines off in awkward spots:

Secondly, at some point this master has been replaced, and whoever did it seems to have continued their obsession with Loctite:

Little wonder that the flare nuts were almost impossible to get off with normal flare nut spanners.
On a third and more annoying note though, what in hell is Mazda doing:

One inverted flare seat, one bubble flare seat… on the same master cylinder. Arrrgh.
Fourth, and most annoying, I have discovered that the proportioning valve was supplied with 1/8NPT to 3/8 inverted flare fittings, not with 1/8NPT to M10x1 inverted flare fittings. So ill have to try and source some 1/8NPT to M10x1 IF adapters from somewhere… only they seem quite hard to come by locally.
This leaves me with a dilemma. M10x1 IF to Bubble are relatively easy to get, and so i could get a new prop valve with M10x1 bubble flare fittings quite easily and then use adapters on that to M10x1 IF.
Another option is to get this: [url]https://www.amazon.com/Wilwood-4444-30-260-11179-Proportioning/dp/B003LT619Q/ref=sr_1_2?ie=UTF8&qid=1547807772&sr=8-2&keywords=260-8419[/url] which does both front and rear circuits in the one unit, but would need adapting from 3/8 IF to M10x1 IF. I cant find any listing for such an adapter though.
The last option is to get some of the M10x1 IF to 1/8 NPT adapters from the US along with a M10x1 IF to bubble adapter for the master cylinder.
All in all though its likely to have to come from the US, because it just seems to be not available here.
Anyone have suggestions?
