Going to be fitting my bias pedal box, may seem like a stupid question but does the bigger master cylinder go to the front or rear brakes? My master cylinder sizes are .70 and .75

.70 to fronts and .75 to backs. Mine is .65 to fronts and .75 to backs.

Thanks mate. Do you know why it's bigger 2 the back? I fort bigger 2 front because there is twice as many pistons?? I'm running valver brakes all round.

Hard to explain. It's like when you put your thumb over the end of a hose, makes the whole smaller but increases the pressure.

It's all about Bernouillle's principle of fluid dynamics. Small hole, same flow, more pressure.

I could use some more examples, but they'd get put in the over 18 section....
