Bleeding Clutch ...

So I used the Motive Brake Bleeder to bleed my brakes and everything went fine. When I use this to bleed the clutch, will the pressure from the Power Bleeder bleed the clutch line as well, or will I have to pump the clutch manually?

as long as the bleeder your using operates off vacuum. hook a clear hose to the nipple on the slave open the valve and bleed away! Try pumping the pedal a few times berfore you bleed it.

You know just as a fair warning the tank for the clutch and brake lines is seperated so even though the tank will "look full" the back of it where the clutch gets its fluid will dry up fast. So have a buddy check the fluid often.

So basically I can bleed the clutch just like I bled the brakes ... pressurize the system using the brake bleeder and loosen the nut on the clutch nipple and wait till the fluid turns blue??

Just out of curiousity, at what pressure did you pump the bleeder to? I know Motive says not to exceed 20 psi...

It wouldn't hurt to pump the clutch pedal a little while you do it with a pump bleeder. I used to have the wife help me. Watch the fluid it drops quick. Did it a couple times a year on my stock clutch and seemed to help it last a little longer. Now on a Tilton twin ceramic.

Where upstate are you? I grew up in Ithaca, and I'll be going back up in 6 weeks. Didn't see many Mitsu's. Whole lotta Subie's though.

Check . A pedal adjustment may be needed, depending on condition, mileage...

We usually make the trip up to Fairhaven State Park for the day. We used to jump bmx bikes of the pier in the 80's. Ahhh the good ol day's.

Good luck with the clutch.

DO NOT pump the pedal while bleeding with a pressure bleeder. At best it won't help, at worst it will draw air back into the system. With the way the clutch master cylinder works you do not want to touch the clutch pedal at all while bleeding with a pressure bleeder.

Your absolutely right . Should have been more specific.

Once you bring pressure up in the bleeder and see fluid flow, push the pedal down once, hold it and tighten bleeder valve. Check your fluid and then slowly pump the pedal a couple of times with the bleeder valve closed until you feel normal pressure. Repeat if needed.

I just used a vacuum pump on the bleeder screw. Worked great.

So did you push the clutch pedal down while bleeding as mentioned above?

no. I never touched the clutch pedal. I hook a mityvac up to the bleeder screw, pull fluid, close the screw under vaccum. Air passes around the threads of the bleeder screw so you get bubbles in the stream but not in the clutch circuit. I do brakes the same way if they won't drain by gravity alone. pumping moves fluid too quickly imo.
