bleeding brakes, soda stream brake fluid

[Neo Badness]

Nope no wheezing mate.. Duno never checked to see if fluid would come out.. I'm guessing they were routed as started I've removed them now as going to re route in the car 

Yeah good thinking re routing inside the car. My mate has done this too on his Mk2 VR and another mate does it on all his competition cars. Remember to put a union in before the bit that goes into the car. Will make life easier if/when you have to replace them.

My master cylinder from GSF that I bought a few months ago has 4 wholes too.  It came with two blanking screws, which is normal. Nothing to worry about there.

I never got blanking screws had to use spare bleed nipples to blank it off. Seems odd though that OEM has 2 and the replacement one has 4. Is that something to do with LHD and RHD? Who knows. Anyway I swapped it out and haven't had a chance to bleed it yet as I'm knackered.

Right, I'm stumped, my mate Alex is stumped. Changed the mastercylinder out for a known good one.
Bled the system and the brakes work, sort of. Theres a lot of pedal travel and after a bit of abuse the pedal will go to the floor when pushed hard.

It should stay above the floor about an inch shouldn't not sink all the way to the floor?

Changed the front flexi's + hardlines back to the M/c with like for like, rear is as it was. Get a strange wheezing sound when pumping the brakes at standstill. Was working fine when parked up in July.  Don't think it's the servo as that's the only thing that hasn't been changed and that would make the brake pedal really hard to push down?

Setup is as follows.

280mm calipers/ discs
standard 16v rear discs/ calipers
22mm master cylinder
9in servo(?) standard 16v one

Only other thing I think I might try is taking off the rear calipers and pushing the pistons back in. Failing that I will have to admit defeat and take it to a garage, who will probably charge me a small fortune, that I don't have 

Any help gratefully recieved.

Did you try clamping both rear flexible brake hoses to see if the pedal was any better?

Nope, I didn't. I do have a clamp though. Forgot to try that. Good info will give it a whirl. Did try it on the front ones but didn't make much difference that I could tell.

If it does make the brake pedal better does that mean I need to wind the piston back or copper grease them up?
 This is all new to me and it's turned into nightmare...

Was the master cylinder you got from gsf right in the end, just tried bleeding my brakes, left it for 30 mins came back and the bottle was empty  Dripping from where the fuel lines go, so obviously the master cylinder. Or the seals that hold the reservoir in place

I hate bleeding brakes, such a pita. Have swapped M/c's but problem is still persisting, albeit not as bad as it was. So I dunno man. Going to have a fiddle with clamping off the calipers and seeing if that does owt. Then have another pop at bleeding the brakes/ fiddle with the bias valve underneath. It's rubbish  too as the weather is getting better and everyone is out in their car and mine is still broken

Lol yer I hate it too, burns and doesnt taste nice either  Took my m/c off and where the black reducer seals go into the m/c, underneath has all rusted so not a flat surface and think it's pissing out of there. How much fluid you used, I just wasted a 1l bottle  http://www.vwh2o.com/vw.cfm?act=shop.product&pID=34848514&lang=EN&country=GB thats the one I'm buying plus got to buy the blank screws separately. £12 for two screws!!! Don't think so.

That looks like the one I got but was from Euro carparts. Paid 12 to get it delivered in a Saturday morning too as I was booked in for track time that afternoon. How naive I was  Mine  I took off was proper fooked just crumbled round where there reservoir plugged in and leaked like a very leaky thing.

Need to sort this Golf and get it out and about peeing me right off. It's not even fun tinkering with it anymore I just want it done. Sigh

Don't think it is the master cylinder as symptoms persist even though I've swapped them over.
