What do they mean by "loosing pressure"?
Is it loosing fluid?
Is it engaging clutch, then backing back off (very unlikely!)
If you depress the clutch peddle the clutch release cylinder must move out about 5-10mm.
What happens when you release the clutch peddle? The release arm should push it back.
If not then you must sort this out first, before concerning yourself about what is happening inside the clutch.
The clutch is quite difficult to bleed from empty.
My method it to:-
- use an eezybleed and open the bleed nipple until fluid comes out without bubbles and clean, then close the nipple.
- Assistant to press clutch peddle fully down.
- When fully down release bleed nipple slightly and note a little more fluid (and bubbles) escapes as the arm is pushed back, then close the nipple again.
- release peddle and then press down again and repeat several times.
This helps to get rid of any bubbles in the slave cylinder as the the bleed nipple is not on the highest point!
It took me several goes to bleed the clutch to give a very positive peddle, with no sponginess or free play.
If you do not have an eezybleed, then just open up the bleed nipple and let gravity work for you, and after a few hours fluid will start dripping from bleed nipple. Do not let the master cylinder run low on fluid!
