I decided to bleed my clutch as it was playing up a little with the gears, etc...
so i purchased the clutch fluid, found the bleed nipple, got my bro to put foot down on clutch and i opened the nipple, a little bit of fluid came out, i closed the nipple.
he then lifted clutch up and then down again, i did the same process of opening and closing the nipple. a little more fluid came out,
on the third attempt, nothing came out and also when my bro put foot down on clutch the pedal went all the way down and stayed there, he had to lift it up using his hand.
Now when we put foot on clutch the pedal goes down and stays there.
how do i sort this, i assume i have too much air in the system, how do i get rid of this.
i have tried pumping the clutch and then leaving it down and bleeding the nipple, nothing comes out :(
done this about 20 times....
i did this with the engine on (don't know if this makes any difference.)
-
mate i jsut did mine this morning and same happened to me bud... i just keeped on doing went through 2 bottles of brake fluid
and i had 3 ppl doing it bud pumping the pedal, keeping the fluid nice high and another doing the bleed nipple.
it should eventually come back! also i took the battery and the tray out so i could get to the bleed nipple easier

2 bottle of break fluid, blimey, how comes you had to use sooo much, my fluid does not even move in the reservoir, nothing comes out of the bleed nipple
How long did it take you?
Did you also pump the clutch a few times before you leave it down?
Any tips would be really appreciated?
Did you do it with the engine on?
did you use any tubing etc,
-
done it with the engine off!,
open the nipple..then push the clutch down...shut the nipple...clutch back up in this order! had to pull it back up by hand quite few times,
see-thro tubing off the nipple into a clear bottle,
gave it a couple of pumps now and again with the nipple closed.
it took a while to get all the air out mate..make sure you fluid resvior is topped up and high because the supply tube for the clutch is at the top of the resvior
-
It really does take ages and alot of fluid.
I bought a vacuum bleeder, sucks on the nipple :laugh:
But yeah its a tedious task and great fun if your doing it yourself - having to jump in car all time and back.
-
you do not need the engine running to bleed the clutch. try opening the nipple a little further but make sure it's closed before you let the pedal back up
-
My fluid level is topped up to the max.
It is such a tedious task to bleed the clutch, i really hope its worth it..
so to clarify...
I open the nipple
then press the clutch
close the nipple
lift the clutch back up again
(the reason i am clarifying the instructions is because i have read conflicting methods and its confusing)
for those people who have done it before, how long does it take? the reason i ask, i dont want to be there for hours and hours and then find out iv done summat wrong,
I have been attempting to follow the above instructions with no avail, no fluid is coming out and also the clutch pedal does not seem to be getting stiffer,
-
yes mate thats the sequence to do it in,
what car have you got mate?...your wee diaphram valve thing like mine might be going...leaks all the clutch fluid out the system when press the clutch down
took me,dad and mum...20-35mins roughly mate
-
Its a VW Golf GT TDI 1999 (T)
110 bhp
unsure about the diaphragm valve thing like. all i know is that i hope i sort it tomorrow as i have work on Monday :(

check that wee diaphram valve mate..mines had cracked due to the cold weather im guessing and was leaking my fluid out so i ended up with half clutch and hard gears! so bought my new one and went thro the stages you are to bleed the system!
when bought the part from vw they said weve had to get about 10 off these in abt 2weeks...over this cold period im guessin there failing!
-
hmm interesting point, the only issue here is that when i pump the clutch pedal, the fluid does not actually decrease in the reservoir so i doubt its actually leaking.
its worrying me a little now as work is coming closer and closer...
i bought a piece of tubing today so i could connect it to the nipple and put it in a bottle ended filled with fluid, i would have assumed i would be able to open the nipple and pump away... but i just end up freezing and getting bored...
i spoke to the guy at the parts shop, he said summat about the rubber tubing might have failed in slave cylinder, etc... ( :undecided:)
If i cant sort it today, looks like il have to push it down to local garage for them to bleed it for me..
Its proper annoying me now
-
you cant just open the blleed nipple and pump away cause when you bring the clutch back up mate and the bleed nipple is open it cause a vaccum and sucks air back into the system! you may have a major air in the system...it possiable to bleed it back up through the system mate? as air rises so im guessing you must have air between the supply from the master clyinder and ur clutch clyinder?
-
what do you suggest i do?
im lost for ideas now.....
i think i have a lot of air in system.... manually trying to do this seems like a hard hard graft...
does air get pumped back in even if you submerge the nipple side with tubing in fluid in a bottle??
i really thought this was going to be an easy task, now im beginning to regret i started it
-
if your not loosing fluid and its staying high, obv there no leak!
i think you have got air in your system, and i got told to try and reverse bleed it pump the bluid thro nipple at gearbox back up the clutch and masterclyinder but then mines started working!
-
sorry for stupid questions,
What pump is suitable? Im running on a tight deadline as i dont want the shops to close...
so basically connect the pump to the nipple via some tubing and pump the fluid in backwards, and force the air out of the reservoir..
If this works is that, would i need to restart the bleeding process via the original method agin or is it sufficient
-
like an easy bleed system that can suck the fluid through and be used to push the fluid back up, so its works like a vaccum one way and pressure the other
yeah thats right mate you push the fluid through the system inreverse it will push the air out at the resvior! i dont think you would need to bleed it as your system will be full off fluid if think about it
-
Just ordered a new master cylinder, will get fitted tomorrow, took it garage today and they told me the piston had snapped, that's why it was not bleeding,
hopefully get my golf back 2mrw.
