A few months back my clutch started sticking to the floor on my 2000 accord so I replaced the master cylinder. The problem was fixed until last week when it showed up again. This time I replaced both the slave and master cylinders. However, the system will not bleed properly. I have tried using a vacuum and just pumping the pedal while someone releases the pressure. The pedal is still soft and doesn't come back. Is it possible that there is a hole somewhere and I am sucking air into the system? What could I be missing? Thanks so much.

When bleeding, does fluid get pushed out of the bleeder valve?

 

Depending on how it's mounted in might be possible to trap air in the slave that won't exit when bled from the slave. You might try pumping fluid up the slave to the master. This will require a hand pump.

good luck

 

Fluid does get pushed out of the bleeder valve. Isn't there only one way to mount the slave (excuse my ignorance)? I have heard about trying that method. I have seen professional tools on Ebay that are quite expensive. Is there a cheap way to force fluid up through the bleeder valve?

Thanks,

I actually read of this problem on another brand of car. Depending on engine mounting, car trim, it may be possible to form a high air pocket trap above the bleed port. In this case w/ ordinary pumped bleeding, the fluid might run by the bubble while bubble stays put. Bubble wants to go up, not down.

You could connect brake fluid to a reservoir held above the master cylinder reservoir and allow gravity to force the fluid up the slave to the master. Fluid may try to leak past bleeder plug threads, but still should work. Make sure no air in tube from brake fluid reservoir to bleeder. Watch fluid level in master cylinder reservoir and don't allow to run over.

good luck
