Hey Im desperately Hoping someone can help me out here. I have. A 2010 Mitsubishi lancer 2.0l non turbo with the manual transmission. I changed the clutch because the slave cylinder was leaking. Replaced clutch and the slave cylinder. Now I can't bleed the clutch. When you crack the bleeder no fluid will come out and pushing the clutch doesn't help any. I've tried using a vacuum bleeder at the screw and nothing comes through. I've tried reverse bleeding and I can push fluid up through the slave cylinder but it seems to not be able to get past the clutch master cylinder and into the reservoir. Does this seem like a symptom of a bad clutch master cylinder?

 

Do you get any fluid flow if you disconnect the clutch hose at the slave cylinder?
Couple possibilities here -
1. Bad master cylinder
2. Crimped or colapsed clutch supply line (hose or hard line)
3. Plugged supply line.
Did you remove plugs from the clutch cylinder threaded connectors (sometimes they are installed for shipping)?

 

The slave cylinder is one that is inside the bell housing. There is no crimped hose or line. I took off where the line connects to the clutch master cylinder and I could get fluid through the slave cylinder up to the clutch master but it wont go through the master. I ended up removing the master cylinder from the vehicle and tried bleeding it on the bench. No matter how much pressure I put on it at either end no fluid will go through it. I'm assuming this means it's clogged or shot?

 

Yes, slave cylinder is inside the bell housing, but there is supply line connection to it on the outside. You can disconnect it and check if there is a fluid flow coming from there before it gets to the slave cylinder itself. Unfortunately it sounds like you have no fluid coming from the master cylinder though, so that might be a place to start.
Just in case, check fluid level in the master first before replacing it.
What makes me wonder is - how is it your old slave cylinder was leaking if the master cylinder is not providing any fluid? Makes me think it has something to do with fluid level in the master cylinder.

 

Yeah I'm not really sure. I pulled it off the car and it seems clogged. I should be able to pull fluid through it with a pump right? Nothing will go through. I've been stuck on this son of a b**** for couple weeks. I'm gonna order a new clutch master and see if it does the trick.

 

I’ve changed the clutch master cylinder on mine new flywheel clutch kit with csc, fluid is flowing but pedal still flat

 

I changed the master on mine and was able to get fluid through after that. But if you changed it out, fluids coming through, and pedal still won’t firm up; you likely have air stuck somewhere. I’ve found reverse bleeding seems to get stubborn air pockets out easier (pumping it through from the bottom instead of top down)

 

Hey did you get this resolved I am currently having the same problem I replaced my slave cylinder and installed a clutch kit and I am trying to bleed the system but there is no pressure
