Clutch Slave Cylinder - Wet!

[bjmills]

I notice my clutch pedal falling - falling - fallen. No fluid in filler tank. Jacked up car, area around slave cylinder is all wet. Shall I just assume that the slave needs replacing? Or is it worthwhile to haul it off and see if it can be repaired, e.g. just a bad seal?

There are no replacement seals - get a complete replacement cylinder.
If you search on clutch slave you should find pretty detailed instructions on "how to"

Thanks for the info... I did indeed find a great deal on replacement, it's because of NSXPrime I was even able to find the slave cylinder

I had my cylinder changed,leaking on a 99 with 15,000 miles.

It's a good idea to change the slave and the master at the same time. With any hydrolic system that has age on it the intensity/crispness of the preasure pulse will be much different between new and old components. If you only replace one of the units expect a failure in the older unit in 6 months to a year because of this difference. I know it can be painfull to replace a good working part but it's a whole lot better to do the job once and have it last for another 10 years +. Like the one saying goes "you can pay me now or you can pay me later" !!!

Thanks for the info and advice, guys. I plan to replace the slave as soon as my SpeedBleeder arrives. Does anybody know what the volume of fluid required is? I'd hate to come up short in the middle of the job.

Don't know the exact amount, but it's fairly minimal. Grab somewhere around a 32 oz. bottle, and you'll never have to worry about running out........ever.

I just finished replacing both master, slave, and slave hose on my 91. I orginally changed the slave, a week later the hose developed a tiny leak, and 6 months later the master started showing signs of leaking down the firewall on the inside of the car. I replaced my Dot3 with Dot4 fluid, I would recommend a speed bleeder, and/or a friend to help bleed it. :smile:

There has been some dicussion, just do a search for clutch & slave... see this link for more info http://www.nsxprime.com/forums/showthread.php?t=42284&highlight=slave+clutch

Of course, once you open a bottle of brake fluid, you're supposed to use it or throw it away, since it absorbes water. :frown:

Wasn't aware of that............Thanks for the info!

Throw it away? Well I guess if exposed to moisture it would go bad. I'm sure if you stored it properly you would be able to shelf it for a longer period of time. Any amount of moisture in brake fluid definitely affects its performance, moisture in brake fluid increases over time the boiling point decreases. :frown: Reduced boiling point might cause vapor by boiling in the caliper, or wheel cylinder which could result is sudden brake failure. Plus moisture in the brake fluid can contribute to corrosion of parts such as steel pistons and ABS modulators. Sometimes depending on the type of fluid, it should be relatively 'clear' as time goes by it will darken, and thicken into a syurpy mixture. So flush that fluid on a regular basis, and your baby will love ya forever! :biggrin:
