Changed slave Help?

Railroadmike · Railroadmike's Garage

Ok so the problem still exist. Changed the slave, the high pressure line has no swelling? I filled the Reservoir with brake fluid and I am using a Motive power bleeder. I installed the new slave, pumped the bleeder to 20 psi. No leaks (except the bleeder a little at a fitting, open and closed the slave bleeder valve three time. Had a strong stream of fluid. Petal still stuck to the floor? Had a friend hold the petal up and repeated. Petal stuck to floor. Took the motive off and pumped the clutch petal, still have the petal stuck to the floor. I am convinced I have air in the system???? Help!!!! Plz

I had the same thing happen when I sucked in a bunch of air while bleeding the slave with a motive. I ended up jacking the ass of the car as high as I could with the front end almost touching the ground. Doing this helped remove the air that was stuck.

Ok so did you still use the motive? Also did u put fluid in the motive or do it dry. ( I have fluid in motive). Did u bleed the brakes, brake master and slave or just the slave? Also if so can I ask what order u used. I am really maxed out with this lol.

as mentioned on the previous post.
1. Jack the back end up as high as possible.
2. Push clutch pedal to the floor and stick a length of wood between your drivers seat and the clutch pedal.
3. Attach Motive powder bleeder. Bring to 15-20 Psi
4. Look for the leaks.
5. Take off starter motor
6. Loosen clutch cylinder bleed screw.
6. Catch fluid in a jar.
7. Tighten screw and put back starter
8. Release pressure from brake master cylinder
9. Fit cap on reservoir
10. Pull pedal back up.

Ok got all that. And I am with u. Just confirm, do I need to bleed the brakes at all? I understand I am bleeding the Slave (Starter is off). Do I need to bleed the Brake master, or any of the four brakes?

I use my motive dry, and that's why I sucked in air, i wasn't paying attention. You're using your motive correct so don't worry about that. I bled the brakes first before I did the slave. I'm not sure if it matters because they are on their own circuits. I also bleed the slave with the clutch on the floor, then pull it up when I'm done bleeding. Not sure if that matters. The normal order is passenger rear, drivers rear, passenger front, drivers front, clutch slave. Hope that helps, let us know.

yes, always have your reservoir and Motive power bleeder topped up.
In OZ, our brake and clutch reservoirs are separate. I believe that the U.S. cars have them combined.

Ty I am gonna try this and hit u guys back.

I thought when you used the power bleeder the pressure in the lines is the reason why jacking is not necessary. I have done my clutch twice and my brakes twice with no problems and no jacking. Am I crazy, why are people jackin up there cars and using a motive power bleeder?

I only had to do it the one time on my car, and I'm thinking when it sucked in air, it got trapped at the top of the slave. I helped a local guy when he put in a new slave, and the only way to get a good pedal was the ass lift with motive procedure. I haven't had the problem since, and I just bleed the system normally now.

How coud you reach the slave bleed screw without jacking the car up? You people amaze me..

Ok we'll I hooked up the motive, jack the rear end very High. Bleed brakes all he way to the slave. Released the petal (motive was still hooked up) and petal just drops to the floor. Think it's the clutch master Cylinder?

Wait, I left the motive hooked up when I released the board holding my petal? Then unhooked the motive. Is that what I am doing wrong???

Since your pedal is already on the floor I don't think you need the wood. After you bleed the slave, disconnect the motive, make sure your res. is full then pull up the pedal.

Right so if I pulled the petal up before Disconecting the motive (motive still hooked up) and it stayed up until I touched it with one finger, then Slam, back to the floor ugh ????

Are we thinking possible bad Clutch master cylinder??

Some history now. The car had no fluid leak when this happened. Reservoir, clutch master and previous slave were replaced 2/10/10. Now it's back to the floor and I started with the slave??? Do I move on to another part?
