Brake Master Cylinders.......
I read on here a while ago that (despite the logical obvious uneducated answer) that the 0.625" cylinder does the front, while the 0.70" does the rear?
Is this the case? If so, please can you explain to me why the smaller cylinder controls the front (bigger) brakes? I need to understand this.
Please and thank you.

I'd always assumed it was to do with that fact that the rear brakes should "bite" first for the sake of stability, when the front brakes kick in, as they will provide far more braking pressure. This should keep everything "true" and in shape.
I may be totally wrong, but just always what I'd assumed.

Btw those sizes are a good starting point and not ideal in all cases.

a smaller bore excerts more pressure per given area, but less fluid movement. and the reverse for bigger cylinders simple !
if your leg excerts 1000psi into the cylinder then proprtionatly the cylinder size will adjust that to the outlet pipe hole. bit like putting your finger over the end of the hose pipe whilsts its running water out.

smaller cylinder gives more pressure due to it been smaller, thats why fronts are usually .625, we did find we needed a .75 for rear cylinders as a .70 was to powerful and locked up the back end.

Theoretics
.625 is a hose pipe
.70 is a drain pipe
.75 is a sewer pipe
Put the same fluid into them and the hose pipe will give you greater pressure (less volume)
The sewer pipe will give you less pressure (higher volume)
