Title: Clutch master or slave leaking
Post by: LA on September 27, 2010, 08:53:06 AM
How do you diagnose if it's the master or slave that is leaking down.  The level is not dropping, but it's certainly leaking down, and fairly quickly too.  

I replaced the slave with an old one that I had from my former 04-S4R that was working fine when I removed it.  No change.

I just replaced the plates and the stack height is a little tight, but it was leaking down before I changed the plates.

I have about 34,000 mi. on the bike now. My guess is master and damn, they're a little pricey.  

Anybody rebuild one before?

You don't mention what bike or type of master.

Radial...conventional?

Sorry. I started to ask you directly with a PM anyway.  It's a S4RS radial master.

Thanks,

I have a friend with a 749...same master. She went through multiple masters/slaves and never could get through a track day without losing pressure.

ducvet put a different brand in place of the Brembo and the problem went away edit: got better but air still seems to be getting in.

Want me to find out what kind?

Alternatively this may take some of the sting out.   http://www.yoyodyneti.com/ProductInfo.aspx?productid=10.8101.10 (http://www.yoyodyneti.com/ProductInfo.aspx?productid=10.8101.10)
