Brake master cylinder bore size - just rear brakes

[EastMT]

What is the common or a good size for a master cylinder for just rear brakes (no front brakes yet)?

3/4 or 7/8. Depends on how u want the pedal to feel and amount of throw.

Thats important info I left out. They are calipers.

Single piston veewee stuff?  I would guess the 7/8 is the better choice.  But somone like @parker@gearone would be better to answer.  The folks at  fodrill were super helpful to me and had parts in stock.  And pacific customs is pretty on to of it.

@lincster & @Bobalos are spot on I’d recommend 3/4 if two piston caliper. 3/4 or 7/8 if four piston caliper. 3/4 softer pedal longer throw. 7/8 firmer pedal shorter throw.
