Clutch bleed help please!!

[Bowlerwell]

Update...

Slave cylinder seems to be fine.
But no fluid coming through the supply line.

Looks like the master cylinder is bust.

Does the supply pipe from the reservoir to the Master Cylinder have a filter, or non-return valve, or something in it?

Yeah i know this post is a month old. just postin this for forum searches.

Your bleeder may be gunked with rust, dirt, etc. Other possibility is the clutch master cylinder is adjusted too 'tight' there should be a very slight gap between the clutch master pushrod and the back of the piston (yeah, the shaft with the 13mm jam nut behind the clutch pedal.) If its too tight it never allows the piston to return all the way to allow fluid in from the reservoir.

3 ways to bleed the clutch...

#1

push the clutch pedal. let it drop to the floor. open bleeder, then close it. Repeat. You will eventually need someone to push the pedal down 'cause the spring wont pull it down after its mostly bled. And of course pull it back up by hand after each time.

#2

Put 10psi of air pressure on the brake fluid reservoir. This can be done with a tire valve and an old modded reservoir cap or a couple other ways. Open the bleeder. Keep an eye on the fluid level. DO NOT USE TOO MUCH PRESSURE!

#3

Open the bleeder. Let it drip for a looooooong time. This method can suck if its slow goin. Watchin the fluid level is no fun this way.

If you have a slight air bubble grab the clutch pedal with your hand push it in as far as you can and yank back on it. Dont crush your hand tho! Repeat this as fast as you can maybe 20X. This method is the only way ive been able to get all the air out of some systems. This can also save your *** on the side of the road. The other variation of this is to push the pedal to the floor and sidestep the clutch a bunch of times. The by hand method works better for me.
