idosubaru Posted October 1, 2009 Share Posted October 1, 2009 replaced the slave cylinder and hose and the "master cylinder" (whatever that's called on the hydro clutch), was also previously replaced. i can't seem to get the pedal right. pedal is loosey-goosey and sticks to the floor. i've bled, and bled, and bled. what am i missing, don't see any leaks.

davebugs Posted October 1, 2009 Share Posted October 1, 2009 Gary, They are very annoying to bleed. I've tried suction and other methods. One of the last things I do is unbolt the slave (if necessary) and push IN on the plunger with the cap to the master off. Often this will get more bubbles. Something else I often do is as soon as I have some pedal I take it for a short ride. I swear it helps get some of the bubbles out - or atleast have them consolidate so they purge better when I get back. Good luck. I'd love to see a definitive how-to on this like the radiator burping instructions. If I know what always worked I'd gladly write it up myself.

Fairtax4me Posted October 1, 2009 Share Posted October 1, 2009 You can use a vacuum pump on the bleeder screw to help draw the air out. The best way is to just remove the slave cylinder and actuate it by hand a few times. I usually prime the slave cylinder before I put it on the car. Some of the fluid comes out when you install it, but at least you know there isn't any air in it then. Link to comment Share on other sites More sharing options...
CNY_Dave Posted October 1, 2009 Share Posted October 1, 2009 Maybe it would help to clamp the slave cylinder into its rest position, or collapsed as far as possible, then bleed? Whenever you pump the pedal, the slave pistion moves (even if just a little), perhaps moving the air away from the bleeder. Driving the car makes sense- the bubbles are like those stuck to the inside of a glass of soda, shake the glass and the bubbles dislodge. So, whack the MC and lines and slave cyl with a mallet a few times during the process. Dave Link to comment Share on other sites More sharing options...
idosubaru Posted October 1, 2009 Author Share Posted October 1, 2009 I did fill it up and hand pump it once or twice before installing. I'll go try some more. Glad to hear they're a pain and not something else is wrong. I did accidentally compress the slave and squish a lot of fluid out while installing though so probably lost most of what i had in there.

idosubaru Posted October 1, 2009 Author Share Posted October 1, 2009 question - are you supposed to bleed the slave them the main cylinder or main cylinder then the slave? they both have a bleeder screw. So, whack the MC and lines and slave cyl with a mallet a few times during the processoh man, i love you guys, that sounds awesome!!! Link to comment Share on other sites More sharing options...

I would bleed the main (not sure it will do much) then bleed the slave, not sure then bleeding the main again would do anything other than risk sucking in air.

fleming442 Posted October 1, 2009 Share Posted October 1, 2009 Gary, check your PM's. I have a pressure bleeder. You are welcome to it if you're in Westmonster! Link to comment Share on other sites More sharing options...
idosubaru Posted October 1, 2009 Author Share Posted October 1, 2009 Gary, check your PM's. I have a pressure bleeder. You are welcome to it if you're in Westmonster! Oh man, thanks a lot but I'm in Morgantown, WV now. It's a friends car, trying to help him out so I'll get it figured out up here. Thanks again.

lostinthe202 Posted October 2, 2009 Share Posted October 2, 2009 question - are you supposed to bleed the slave them the main cylinder or main cylinder then the slave? they both have a bleeder screw. I would guess that you would bleed whichever is lower first. Air rises, so which ever cylinder is lower to the ground would be bled first. I've heard of tapping the lines and cylinders before. I've done it and not done it on bikes, cars, trucks, and sometimes it works and sometimes it doesn't. Take that for what it's worth. Will- Link to comment Share on other sites More sharing options...
idosubaru Posted October 5, 2009 Author Share Posted October 5, 2009 went to follow-up bleed it and it seemed perfect? i didn't bleed it at all, haven't driven it yet since i'm finishing up the timing belt. i'm returning it to my buddy today and driving it in to work so we'll se how it does. i tapped the solenoid/lines with a hammer before trying so either sitting for a few days helped or the hammer trick did.

davebugs Posted October 5, 2009 Share Posted October 5, 2009 Sounds like you may have it done. But a little DOT3, wrench for the bleeder and a rag to put under it wouldn't be a bad idea to take with you. Link to comment Share on other sites More sharing options...
idosubaru Posted October 5, 2009 Author Share Posted October 5, 2009 drove fine, we'll hear from him how it goes i guess later (or hopefully i don't hear anything). Link to comment Share on other sites More sharing options...
