You have braided hoses? That's the first thing to try fitting.
The corsa pedal is always spongy, I got the valver brakes on mine, and theres still a fair bit of travel, but they do work

invest in a pressure bleeding system. they are about £15 from halfords, use the pressure from the spare tyre and a resevoir of brake fluid then undo the nuts individually and let the pressure push the fluid through the system, works pretty well. even a slight bit off air in the system will make the pedal feel spongy.

well it pressureises the system so you can open the valves individually without pumping the brakes and withough having to top up the resevoir. essentially a 1 man method.

I have had this problem, jus loads of tiny tiny air bubbles in the system. Like others have said tho they always a bit spongy compared to others. If the pistons are bigger then u will need more travel to get the same effect, but as far as i know they should be the same. Some cavaliers take the same brake pads as corsa's u c so the calipers are almost identical.. most of the time its just the caliper mounting bracket that holds it further out so u can have a bigger disc.
As for the bleeding, its cheaper if ya can borrow a m8 for about 20mins and do it the old fashioned way!

i have had this problem and am yet to get it sorted various people mechanics have tried bleeding there is no air in system, I just dont think the corsa cylinder has enough displacement to do the job (get a really firm pedal with no travel)

All the above sounds familiar. The brakes are good but the pedal feel is pretty poor.

just my luck i went to halfords this mornin and sold out of this pressure system so no more news on the brakes but ....
i tested the brakes by taken both wheels off the deck and startin it up and engaging a gear and braking and it stalled the car !
