Hi folks,
i'm feeling rather guilty here. This is my first post and i'm already asking for help. :embarassed: Anyway, i just bought a 91 MK2 Gti. With the understanding it needed a new brake master cylinder. This was no problem and wouldn't be that expensive to replace. So i bought a Delphi Lockheed master cylinder and proceeded to fit it. Stupid me i didn't notice that it requires two plugs for the opposite side of the hard pipes! I've scoured the net hi and low and can't find these anywhere :cry: If anyone knows where i could pick these up please let me know. Again, sorry for not going through the new members forum thread. I kinda wanted to wait till i got the car going, so i could experience the thrill of the GTI first.
Thanks in advance
Fishyboy :smiley:

ahh you mean the two plastic grommets that go in the other side of the brake cylinder to blank the sockets off. err, i would have thought they would have come with the cylinder? this kindof thing normally does...I had a look around for some with no luck.
-
Your old master cylinder should have steel blanks in it.
If not you're off to VAG to get new blanks.
-
I just got one from gsf and i bought two brass blank screws aswell to block these off. they were a squid each. Handy thread by the way.... Ive just fitted my new cylinder and the car needs to go a mile an a half down the road for a full system fill and bleed.. Sounds sketchy i know but its a quiet road and im gunna handbrake my way there, is it ok to pressurise the servo with next to no fluid in the system? or would it be a better idea to disconnect the vacuum hose? just dont wanna break anything else! im not worried about bones! :grin:
-
Just fill it up with fluid and pump it through with the compensator valve open. Work through the nipples closest to the master first.
Even if you still have a bit of air in the system it would be better than what you're suggesting.
Driving it on the road with no fluid would be bloody stupid and incredibly dangerous. Imagine if you hit a pedestrian on the way? You won't be covered by your insurance and you'll get sued for a LOT and payments may well last decades.

bleed nipples fit the holes for want of a better solution (the larger ones)

Thanks for all the replies and help folks. I'm off to VAG tomorrow to pick up a new tailgate lock anyway so i'll ask when i'm there. I thought the blanks would've come with the master cylinder as well but when i asked my supplier he'd never even heard what i was talking about! Knows his stuff eh?? :shocked:
I had a scout on fleabay but the only bleed nipples i could find were off a Harley Davidson!
Afghan Shocks, I think Diamond Hell is right. Don't take the chance. If you hurt someone or get pulled by the plod you're in serious trouble!
Anyway, thanks for all the help. I let you know how i get on.
Cheers :smiley:

An alternative is a scrapyard - should have something with the appropriate blanks in there.

Sorry was alf asleep and was having a dense moment! Kwik fit shouldnt be allowed to touch brakes... "you have to close the compensator valve" i said... "No you dont" they said, did they work? they they f**k! "now do it with it shut" i said, "wont make a difference, you fitted the cylinder incorrectly" they said... do my brakes now work, Yup!

Kwik Fit!!!! I've had really bad experiences with them! Went in for pads once and they wanted to renew my whole braking system! And they wouldn't do the pads unless i bought all the stuff from them! :evil:
Not got many scrappies near me, most of the stuff they have is like 1.0ltr Renault 5's and the likes. I'll make a few phone calls though!
The Master Cylinder that's on my car at the mo has only two tapped holes for the hard pipes to fit in. Originally for a rhd only. The one i bought must be a sort of generic one. Had toyed with the idea of bolts and ball bearing but quickly dismissed this due to the fact that this is a braking system! :undecided:
-
Correct thread short bolt, plus copper washer should see you right.
-
Plus some locite hydraulic thread sealant would be more the adequate
-
basically original VAG cylinders fitted to MK2s tend to just have just the 2 holes, others blanked off depends how old they are. New cylinders tend to have 4 holes! 20/22mm cylinders may differ too, but on my 8v it had 2 holes and my new gen vag 22mm one it had 4!
IIRC the thread pitch is M10x1 if its any use to you! If so most VAG threaded coolant/oil temp sensors will fit, brake fluid temp gauge anyone? :grin:
edit: can get the plug from VW:
172 611 430 - plug, m10x1 - 10.18 :shocked:

I dont trust Kwik Fit or any other "tyre garages" they employ monkeys and pay them in peanuts i swear.The boss always has a really badly modded scooby too haha. some guy at a similar establishment told me that i had a "major oil leak" and that oil was "spraying" from the engine somewhere, and covering the hub in oil! i pointed out that the stuff on the hub was a dirt and grease build up, not oil. He then told me that it could be my "middle gasket" i asked him what he meant by this, and all he said was that it was in the middle of the engine, and if that goes your f**ked. well what a load of sh!t.
Afgan socks, invest in an easy bleed, its the best thing ever for bleeding brakes! it uses the pressure from a tyre to keep filling and pressurising the brake resivoir, which is the equivilent of frantically pumping the brake pedal. i flushed my brake system the other day on my mini, it took about 15 minutes :D

halfords long life pads were the funnest, pads had died bought some from halfords as it was the only place open and got offered free fitting so thopugth carry on then it's not like you can bugger that up so somehow manage to fit long-life pads instead of the ones i wanted. just thought what a bunch of muppets and thought nothing more of it till decided i wanted to have a play within 50 miles of having pads fitted they were gone. they really didn't like getting hot, they stink and dust something special so go back in for the free replacements :)

Hey folks,
sorry it's taken me so long to reply. I've been working flat out on the car. Well i decided to change all the calipers as they car has been sitting for a year and they were all seized. So once i changed them, i managed to remove the bleed nipples. These were just the right size for the brake master cylinder and it gave me the option of another bleed point. SORTED.
Cheers for all the help.
