How to bleed clutch

Postby okeycokey » Sun 29 Aug 2010 10:05 am

grrr, just got in to the car to find when pressing the clutch down that its stuck to the floor. Reservoir completely empty, investigation has found a connection loose and leaking. Have tightened up but now need to bleed the system, i'm off (in a taxi!) to halfords to get an eezibleed system and some fluid. Never done this before, what is the procedure please?

Follow the instructions with the Eezibleed & you shouldn't have a problem.
Be sure the cap fits properly on your master cylinder & you have a piece of suitable tube to push over the nipple on the slave. Put the other end in a bottle with a small amount of brake fluid, slacke the bleed nipple & when the bubbles stop you're done.
Use a PROPER nipple spanner to avoid rounding off. I usually check before setting everything up with a hex socket to make sure the nipple will undo!
I've had an Eezileed for years & its a great piece of kit, saves all the hassle & makes what are difficult systems easy!

BTW if anyone has a vehicle with a concentric clutch slave cylinder - fits round the gearbox shaft & you need the box off to replace it - it is recommended that you DON'T use pressure bleeders.

thanks paintman, just got back from halfords to find that the copper nut and washer to fit the cap the pipe are missing!!! grrrrrrrrrrrrrrr - before I spend another £16 in taxis to get another one, I think i should check it's definitely an air problem... the post was empty and I saw fluid from the connection so I tightened that up. The pedal clunks to the floor and then I manually clunk it back to the top again. Is that sure signs of just being air in the system?

right, in the end I didn't bother going back to halfords and just blead the system by pumping the pedal (inbetween filling up the reservoir) and I managed to get the pedal back. I don't think the fluid had been replaced for a long while as it was almost black! Fingers crossed that's fixed it and I won't have any issues...

Well done that man. Nothing so satisfying as repairing it yourself.... :wink:

If the clutch fluid was that bad, how's your brake fluid?

That's exactly what I was thinking when I saw it! Will have a look at it tomorrow when(and if!) the wind and rain has stopped...

I have always found that my 90 clutch will self-bleed without the need for an Ezi-Bleed or a second person (I keep the Ezi-Bleed for the brakes where it is excellent). I make sure the clutch master-cylinder is full, undo the bleed-nipple and allow the fluid to run through whilst keeping the master-cylinder topped up. When the new fluid has run all the way through I nip up the bleed-nipple and press the peddle a few times, there is bound to be a little air in the system but I have always found that on the clutch system this will find its way to the top very quickly.
