I changed the brake fluid on my 2008 Outback. Then thought I would change the fluid in the clutch system. I learned its very easy to get air into the clutch system. I tried at first using the one person bleeder I use for brakes. Air must have gotten in, and I lost all hydraulic power. Then got my daughter to help and did it old way of one person pumping slowly, open the bleeder on the way down, close bleeder , release pedal. I was able to get the air out, and the clutch works fine.

Anyone else find this happens?

I just replaced my stock clutch hose with a stainless aftermarket unit. I had the benefit of having my engine out at the same time, so it was easier to work on than what you had to work with.

In my case, I replaced the hose > filled up with fluid > attached bleeding hose to nipple (with a catch bottle) > loosened bleed nipple while manually compressing the piston > tightened the nipple and then released the piston. I cycled through until I had nothing but fresh fluid with no air-bubbles. I had to fill with fluid several times.

Note: You need to not overfill the system with fluid. As the clutch is depressed, the fluid level rises.

In your case, it sounds like you had either a big bubble that moved down or a leak. I had no issues in my case and I'm not exactly a pro at bleeding hydraulics. I take it that the clutch would not dis-engage?

In a pinch, you can often gravity bleed a clutch system. Just top off the master, crack the bleeder on the slave and let it drip. Close it up, top off the master, check the pedal. Repeat a couple of times if necessary to get a good pedal feel.

It's not as efficient as other methods but sometimes you get stuck, with no helper.

I’m having the issue of I had my clutch replaced a year ago and the other day the clutch just went to the floor& will not pump up. I replaced both master & slave cylinder, clutch pedal still will not pump up. When you push the clutch in you then have to manually pull it back up. Please anybody!!!!!

I'm not sure but like a Brake MC do you have to bench bleed it before installing it ?

The instructions comes with the new MC ?
