I just replaced my clutch and got everything back together but now there's a problem with the hydraulic system. It tends to stick to the floor but when you pump the clutch pedal, pressure returns and the car shifts fine. I replaced the slave cylinder twice so this doesn't appear to be the problem. Do you think i have air in the line? I bled the **** out of it for a long time last night and today. Please help

 

oops my bad, how did you bleed it?

 

the bleeder valve located on the slave cylinder. Hook up an 8mm wrench to it, hook up a tube to the nipple, have somebody sit in the driver seat and loosen the bleeder, have them push in the clutch, tighten bleeder, clutch out. Loosen bleeder, Clutch in... tighten bleeder, clutch out... etc. Any ideas? I think it's just some air in the system... i hope

 

how much fluid did u go thru?

if you replaced the slave cylinder....u may have a bad clutch master cylinder

 

do you have a lot of fluid on your firewall near your clutch pedal assembly?
under the steering column

 

no fluid near the master cylinder, i replaced the **** out of it about a week and a half ago. Since then, i haven't driven it. My throwout bearing went bad and i just decided to replace the clutch but before i knew it was the t/o bearing, i thought it could be a problem with the master or slave cyl, so i replaced them both. I bled about a 32oz bottle worth of brake fluid (actually a little less). If it was an air bubble shouldn't it have come out when i bled it... could an air bubble be caught in the master cylinder?

 

try this way.....pedal in...open bleeder......close bleeder pedal up


opening first can possibly let air into the system....

strange though...u changed everyting and your still losing pressure


may be a stupid question but what are you using for the clutch fluid?
i say its stuipd but my friend used gear oil in his

also have you tried adjusting the push rod on the clutch pedal assembly?

 

I don't think that your method will work but i'll try it any way. I bled it for like 10 mins straight earlier. I'm using dot 3 brake fluid of course. I haven't tried adjusting the pushrod assembly on the pedal assembly but it's definately a loss of pressure. I took it for a 20 mile test drive tonight and it's fine as long as you pump the clutch pedal once or twice. If you're just cruising down the road for around a minute or so and you go to push in the clutch, there isn't enough pressure to actuate the clutch. If you let the pedal out and then push it in again, pressure returns.

this is how i bleed everything....clutch and brakes

 

alright i'll check it out. so let me know if i'm getting you right here... clutch in, loosen bleeder then tighten bleeder then clutch out? then what?

When I do it the pedal doesn't come up by itself. I loop a string around it so I can pull it up.

This way you're making the slave piston move each time. This helps free up any air bubbles that are 'stuck' inside the slave. Sometimes it helps to rap on the slave with something to dislodge bubbles. Someone suggested that for brakes & it should work here too...

 

Hey, also you might want to check all of your clutch pipes... I actually had a crack in one of my clutch pipes somehow, and it leaked a lot of the fluid out, and I unfortunately found out at a stop light at a busy intersection in Des Moines.

 

your clutch master cylinder might be leaking!!!check it out...

Especially the rubber hose part just near the slave. It might be ballooning up, then the slave never gets the pressure...

 

i don't believe i have any "rubber hose" parts near the slave. I took it somewhere today to get pressure bled and they bled some air out of the line but it still isn't 100%. i'm thinking that honda sold me a bad master cylinder or somethin. Oh well it's driveable and i have to make the drive from AZ to los angeles tomorrow so it'll make it. I just won't be able to work on it over there because i don't have any tools at my apartment. I'll probably just end up taking it to this cool old japanese guy with a honda shop about 2 miles away from where i live. He did my brake master cylinder when it went out and i had no time or tools during the school year to change it myself.

I don't have a Prelude... but the engine moves too much for an all-steel line. On my Integra, there's a steel line about 10" long from the slave to a bracket on the transmission. Then there's a rubber hose over to a bracket on the fender, where it goes back to steel line.
