- Thu Apr 29, 2010 9:36 pm #191035 Okay so i changed the clutch master cylinder & slave cylinder already (Both New). While partial/half way through bleeding/pumping the clutch pedal drop to the floor WTF......(Pedal is suppose to drop to floor ONLY when the slave valve is release) So i have someone pull the clutch pedal back up to Normal postion & press it back down again & While i was up front listening i can hear air leaking through the seals of the Slave cylinder......I'm thinking maybe i was giving a bad Slave cylinder, but the seal looks very good........But

I called AutoZone again so they should have a Slave cylinder replacement by tonight......I should be able to try bleeding it tomorrow again....If same problem arise..I'm done for & probably taking it to the shop.......

If i can hear air leaking out of the Slave while the clutch is being press down...I'm sure air is some how passing these 2 seals??????? But shouldn't air be coming out of the bleeder valve instead of pushing air pass the 2 seals below.....

***Note: Seems like the clutc pedal is not even getting really stiffer as i am bleeding some how, maybe this can be a problem why air is some how leaking at 2 seals***




Thanks In Advanced Ricer's

- Fri Apr 30, 2010 3:23 pm #191136 the slaves are the same between civic and integra, and from what it sounds your slave went bad, i would be sure all your connections are tight, and you dont have any leaks, other that it apparently leaking past the seal.... also make sure your bleeder screw is tight when you re-start the bleed sequence...

hope this helps...

- Fri Apr 30, 2010 5:01 pm #191146 Yeah i'm not sure if the slave went bad or not cuz it's new...But it could be defective somehow so imma go replace it with another new one frm autozone today....This the first time i'm having trouble bleeding...Suppose to be a easy process but it's geting on my last nerve.

- Fri Apr 30, 2010 10:46 pm #191226 Bleeding a brand new, dry slave cylinder is actually kinda difficult without either a positive pressure bleeder or a vacuum bleeder. It's nearly impossible to get all the air out due to the design of the fluid passages.

I did figure out another method of bleeding the slave though. Take a half full bottle of brake fluid, stick a hose in it, put the hose on the bleeder screw, crack open the bleeder screw, and pump the pedal. Because the hose is submerged in fluid, it will 100% exclude air from the opening of the bleeder screw.

I'm sure some of you have done this before but I never knew about it until I was replacing mine a few years ago on my last 'Teg.
