Although in my application this isn't for a Corsa-B the servo and master cylinder are, I am using this setup in my Nova. I am all set to fit Calibra V6 front calipers but I read on MIG that certain master cylinders are not up to the job is pumping enough fluid to the much larger caliper pistons and I am limited to the 256mm setup.
The servo and master cylinder are from a late 1.2 Corsa.
Is this true? If so would fitting a GSi master cylinder be any bigger and do the job??

i didnt think there wa any differnece in them possibly might be but the v6 set up aint all that great on corsa servos and masters, best bet is cav turbo calipers smaller pistons

Turbo pistons are only marginally smaller though, anyone else got any insight?

I am thinking 350bhp and heavy track use might overwhelm them lol

I was thinking maybe putting up with it for the time being, the car will need buckets of testing, running in and mapping so maybe I can use that till I afford 4-pots or something.

ive got same problem with mine v6 calipers discs and cant get brakes to bleed poperly i think the master sylinder is at fault but even my last corsa had spongy brakes , the pedal travels alot more as the master sylinder struggle sputting all the fluid to the piston,. someone said to use the v6 master cylinder but i dont know if its a straight forward fit

You can't fit a bigger master cylinder from the vauxhall familey the corsa set up is quite unique, iv heard of people modifying a late 90's mondeo one to fit other than that ull be looking at a pedal box if it's for track use
