I have a fiat master cylinder for my 3 wheeler build. It has 2 circuits each with 2 ports. Can I just block one up for the "missing" rear wheel?

Also, do they deliver the same pressure per circuit or per port? I don't want to double the brake effort at the rear wheel by only having one of them.

i would think about connecting them both up with a T piece, and the output from the T goes to the brake.

oh yeah, that might double the pressure though...

Pressure will not double, the only difference will be less pedal movement, about 10 - 30% less, as the fluid circuit will be a bit less.

I've never used a fiat cylinder, but I would "assume" that they are similar to everybody elses, in which case yep it will be fine with 1 port per circuit blanked off, I have done this many times with peugeot 205/106 cylinders which are great little items for special builds with no servo!
