3rd slave cylinder in a year!! WTF??

Sam, when you put the slave in - did you leave the bleed nipple "open"?

Bentley says to install it and then bleed. I have heard some just push it in there against the pressure? I was able to get my slave in, unbled. There was NO pressure on the pedal, it would not even come off the floor, when it did it was erratic. Whether it is enough to break the seal or fork I don't know.

I ended up taking the slave out again. Opened the bleeder valve and, while being squirted by brake fluid, installed it in the "open" position and then bled all the bubbles out. It was a PITA but the pedal worked much better. Just a thought…

I didn't replace the guide tube. It seemed fine. No appreciable wear and all the little ridges seemed fine. I just cleaned it really good, greased it, and assembled everything. That's a good thought tho... In this case, I'll just install the new slave and monitor it for leaks. If it start leaking again, I'll prob go back in and do the guide tube.

Homeboy, the slave actually isn't really that big of deal (or I'm just getting pretty proficient at changing them). I just push it in against the piston pressure/spring pressure and click it into place on its boss. There's a ridge on the backside of its mounting boss that will hold it while u thread the 13mm head bolt in. In my case, the system is already depressurized as soon as I removed it.

Thanks for the tip tho.

What's funny is I can do a slave cylinder in about 10 minutes and that includes putting the car on jack stands and removing the left rear wheel. I should be on a race team pit crew... While everyone else is throwing new tires on and whatnot, I could be charging around doing slave cylinders. Lol

Took me 4 hours to put mine back in. No joking. However, that was the first time I did it.

i don't remember any ridges on the guide tube.

They're very shallow and run the length of the guide tube. Act as a keyway that fit into the TO bearing.
