Yes my existing one will fit on i have just cleaned it up and checked it over and it looks okay. I hadn't thought to put the original one on it so thanks for suggesting it. I'll order the 0.75 master cylinder from car builder solutions and see how that goes

i used a 0.7 with the plastic reservior ,
going from 0.625 to 0.7 or0.75" means the pedal travel will be less on the larger diameter but the pedal prssure has to be higher to get the same hydraulic ratio at the brakes
the sizes change when larger diameter caliper pistos got introduced as there has to be som reserve in the travel/displacement
dont think type 14 had a 0.7 but Vit & gt6 with type 16 certainly went to the larger bore
land rover ones are cheap and often used for replacements

i'm looking at the 0.75 bore from Car builder solutions https://www.carbuildersolutions.com/uk/075-brake-and-clutch-master-cylinder-without-reservoir
Am I correct in assuming that the plastic reservoir https://www.carbuildersolutions.com/uk/single-brake-fluid-reservoir-without-bracket-and-diaphragm would just screw into the master cylinder as they are both the 7/16 UNF fitting?
Also would the height of this reservoir on top of the master cylinder be to tall to fit under the bonnet height of the spitfire?

Hi All,
I am looking to get a replacement Brake Master cylinder for my triumph spitfire IV. When I bought the car it originally had a 0.75 inch bore diameter master cylinder fitted which worked very well and felt really nice to operate but unfortunately only had a small reservoir which was the same size as the clutch master cylinder which I wasn't happy with. Within the spares I got with the car there was a master cylinder which had a larger plastic reservoir (which I can see from restoration pictures I got with the car was the type fitted before it was restored) but only a bore diameter of 0.625 inches (standard spitfire IV size). I cleaned this up and fitted new seals to this master cylinder and fitted it to my spitfire. From then on I never found the brakes to be as responsive or as sharp as when I had the 0.75 master cylinder fitted. Now that the 0.625 master cylinder is leaking between the plastic reservoir and the ally main body I’m looking to get a replacement master cylinder but in 0.75 inch bore with the larger capacity reservoir. I've looked on the websites of all the usual suspects but they all seem to sell different ones and different GM part numbers (GM205, GM209, GM220, and GM224) but not all say the bore diameter size of them.
Can anyone help locate the type of master cylinder I am looking for?
I have attached a photo with both of the master cylinders

Hi Richard,
My overdrive was functioning but would Slip under power when overdrive was engaged and not put drive through fully to the wheels which wasn't surprising when I found that half the outer band was missing
