Default Sticky Clutch when warm

Good evening all,

When driving the Ax15 all is fine until the cars warmed up or been driven for a little while the clutch sticks a little so itís hard to get to the biting point on the clutch. Could this be one or all of the following?

(I had a new new clutch recently and all was fine until a few months after the replacement.)

1: fluid in clutch master/slave cylinder dirty/tainted?
2: clutch/master cylinder on its way out
3: problems with the new clutch/throw out bearing
4: the pedal itself, Iíve noticed there is a little play where the cylinder rod and pedal meet, also, I have to pull the clutch pedal about an inch towards me to have it all the way back, it changes gear and drives no problem regardless if I do this or not.

Any ideas would be good! I guess a good flush of the clutch cylinder wouldnít hurt any way, is it awkward to do?

Check the fluid level first in the little container . Fluid should be close to the top full (about 5-10mm from top). If fluid Ok than take it back to the guys who replaced the clutch to have a look at the issue .
It could also be a gear selector or gear box issue(oil maybe) . Not sure..haven't had that problem yet .

I had a look in the master cylinder reservoir and looks compromised. It was black with a brown layer on the top! How do I flush this do we know? Thanks

Suck all the crap out. I use a syringe. Check to see if you have a bleed nipple on the slave. If you have, put a hose on it into a bottle, fill the MC with new fluid & loosen the bleed nipple & pump new fluid through checking the MC regularly & refilling.
If you dont have a bleed nipple, you can remove the slave & move it up to above the master. It can be done. Then remove the spring clip holding the piston in & pump the peddle once to remove the slave piston. then fill the slave with fresh fluid & push the piston back in all the way. This should push the dirty fluid all back to the MC & you can then syringe it out & refill with new fluid. make sure you put the spring clip back in the slave & then put it all back. You may need a bit of force to get the slave piston back & all the way down the slave if the line is blocked or damaged.
The alternate is to buy a new MC/slave that is prefilled & install it

Hi,

If this doesnít work, do I need to get a sealed unit replacement or can I just replace the cylinders and leave the hose in place?

It seems like a very awkward job to replace the whole unit. Iíve watched a few videos on Youtube where they have just replaced the cylinders and seems to work.

Would these work?

I have no idea what the pre update ones look like. That ebay MC is not exactly the same as the update one (98-2001). The slave looks about right. Probably if you can make your fluid line bend so it fits up to the MC & slave it would work. If the pre update like you have looks like the ebay ones, it would be worth a try. I am concerned that the mounting flange on the MC may be different (different distance between the bolts).
