Clutch Slave Cylinders keep dying!? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Note, this is on a Datsun 510, not a 240sx, but its an SR, so I thought I would ask you guys.

When I installed my S13 SR20DET w/5 speed tranny, I put on a brand new clutch clave cylinder with m brand new ACT "street" clutch. The slave cylinder is for an S14 USDM 240sx. I went on perfectly and worked great for a while.
When all of the sudden on day, a guy was pulling my car off the dyno and the clutch slave cylinder just erupts. The car has only maybe 700 miles on the clutch/cylinder. SO we put the car on the lift and pull it off. I remove the dust boot and disassemble it, I notice that the rubber seal(the part that is inside the cylinder) is torn.
So I get a new one from Autozone for a 1995 240sx and install it, bleed it with new fluid, and I am back on the road.
Yesterday, I was under the car for something, and I notice a fluid drip from the dust cover of the clutch slave. Note, the car has only been driven about 500 miles (and about 9 months has passed) since the last clutch slave blew.
So I drain all the fluid from the clutch line and it comes out a brownish/red color, thats weird....
So it looks like this cylinder is getting ready to die too, since it is leaking.
Why am I having so many troubles with clutch slaves?
And why has my fluid gone from clear to brown/red?
Does it have something to do with the stroke of the piston not being long enough to disengage the clutch?
Any input?
In the meantime I will do some more searching and see what I can find.
thanks for the help.
