Have they always felt like that?

Have anyone pushed the pistons back in without the res lid removed?
This can cause an issue with a rubber seal, it escapes me which one, I want to say master cylinder.

I tend use a compressor driven vacuum bleeder, which avoids a lot of problems. Have you tried doing a full bleed with the engine running?

I always use the same mot man and according to his brake testing rollers, the little corsa's brakes are better then the omega 
Brake pedal has always been firm but with very good feel 

Have anyone pushed the pistons back in without the res lid removed?

Not to my knowledge

No
Rapidly running out of fluid / nearly 1 ltr used already

Anymore info on this please ?

More importantly how the opps do I find out were the problem is and how do I fix it ?

I think, in your position, I'd be swapping the master cylinder out - as far as I know that's the only way to determine if it has failed, once you've eliminated the rest of the system, which you appear to have done.

Only other thing would be to blank off the master cylinder outputs and press the pedal, if it still required >1 press then it's definitely master cylinder - but that's just as much work as swapping it out..

If the cap was off when the pistons where pushed back, it shouldn't be an issue. I just remember this coming up on VVOC when I was a Vectra owner.

If you are 100% happy everything bleed correctly & the new parts aren't faulty, then it leaves 3 possible places to investigate.
1. Master cylinder.
2. Servo
3. ABS Pump

Jesus, why couldn't mini me break it in the friggin summer 
Its a strange one 
Brakes was fist class before this.
I know he hammered the pedal when it happened basically to stop as he was reversing out of a parking spot into the road at the time 

My next thought was I had air in the abs pump 
If so, how do I clear it ?
I have never pulled a master cylinder apart before so reluctant to strip that first 

Again, 'dangle berries' its friggin cold outside

Usual is that the rear auto adjuster is not working and the handbrake shoes are having to travel a lot to make contact with the drums.

Good idea! I didn't consider the obvious.

It's worth considering on anything that has auto adjusters on rear drums. Which is pretty much anything designed in the last fifty years. Freeing off the adjusters was one of the first things I used to do on any Capri I had anything to do with: that instantly cured the long pedal that others had all sorts of complicated and expensive cures for.

Pull up the handbrake and try the brakes a couple of times,if pedal becomes good then adjustment  is the answer,if not the master cylinder is probably at fault through a seal failing 

[tigers_gonads]

Just had a word with mini me who i've made do most of the work on his own car for a change 
I can now confirm that both the adjusters were wound all the way back for drum fitting and i've just had a look under the handbrake to find the cable is still slackened off totally 

Thanks for all the input lads and if it isn't too cold tomorrow, i'll tighten the cable and see if I can get to the adjuster via the back plate and take it from there ............ 


Right, off to work 

[tigers_gonads]

Ello peeps, hope you all had a good Christmas and New Year 

Another update on this sack of shite Corsa 
Basically due to work and the friggin cold, it wasn't touched for weeks.

After much pissing around with the rear end, I came to the conclusion that the master cylinder must be fubar'd 
Mini Me ordered one off eBay which due to mini me been a tit and not reading the advert properly  turned out to be the wrong friggin one  .
Anyway with some fine pointers from dad he ordered the correct one next time 

That one was fitted today and everything bled AGAIN just for good measure.
The short version is we now have a very good pedal and the car now stops again 

The rear brake adjustors need winding off quite a bit because the cable is tight and the rear brakes are definitely holding on but a least things are getting there (and mini me is learning hopefully that dad isn't always going to fix his car for him  )

As always, thanks for the help

Don't forget to wash the wrong master cylinder before sending it back

[Marks DTM Calib]

And there MUST be slack in the handbrake cables when released (which is a piece of piss to adjust from inside the car when the handbrake boot is removed)
