You can get TRW or Britpart.
Delphi are another alternative brand.

I've had no issues with Britpart wheel cylinders.
However, I would go for good branded master cylinders.

You can use your S2C 10% discount and save a bit of cash  :gold-cup

Hi,

If memory correct, the CV brake cylinder looks like a clutch cylinder, while the CB has a big hexagon nut thingy on the blunt end.

For a 109", your brake master should be embossed, maybe stamped 1" ...

DO NOT fit a 3/4" brake master to a 109" ... it will require about twice the pedal travel, which is scary, but only about half the pressure. Fitting 1" brake master to an 88" will give the opposite effect ... short pedal travel, but the effort required will cripple you. My choice is 109" twin leading shoes on the front, and 88" cylinders on the rear .... shorter pedal travel with self wrapping front brakes. It worked for me, but make your own lifestyle choices.

PS.  CB = Centre Barrel which I don't like. CV = Centre Valve, which I can understand, and are easy to work on.

PPS. The S3 uses a 3/4" CV master, and has an integral (but small) reservoir. I have used them as both brake and clutch masters, but not a good idea as the flange is at an angle. I suspect that an Austin Gypsy (Romany) 3/4" clutch master could MAYBE replace both masters on an 88", without tipping ... but do your own research.
