doesnt fit. tried it. unless you do major work. a mondeo one fits with work i belive. why would you want to? if adjusted correctly a standard one works fine with 288 up front and 260 discs at the rear. remove all the free play between pedal and servo. done this to mine 4 years ago good pedal feel no probs.

reason being the 22mm one was ment for 2.0 brakes ect and takes the shit pedel feel away.Good for people with rear discs to as they work much better to.

anyone with any info and pics of work would be good

I fitted it to my track car, you have to block off two of its outlets, make new pipes and also grind a small part off the casting so it clears the wiper linkage:

Only thing with it, is the top brace has nowhere to bolt into, but Im sure someone could figure it out

it could be done with a good machinest, be a few people wanting an uprated master cylinder for a corsa thats a perfect fit with no other mods. with a lathe or mill and correct boring tool it would a simple job.

Fitting a 22mm cavalier master cylinder really helped bud,replaceing all brake fluid as am guessing it's never bin done? It's a good idea to replate it ever few years! The pedal can be adjusted although am unsure how...u2u dave think he knows

Two blanking bolt's to blank two of them off,yes run two new lines to the four way splitter you need four male brake line fitting,new brake line 3/16 size. Ebay best place..loads of good cheap stuff. The new 22mm cavalier master cylinder needs some grinding down a littleyo clear wiper arm. I can u2u come pics if you like bud. DON'T bover going to vauxhall for one it's about £75+ at a guess go to your local moto parts place it will be about £45 new needs to be a non ABS one or just go get one from a scrap yard.
