slave cylinder issues

[last254]

Hey guys, so I drive a 87 comanche 4x4 4.0L. It originally ran the peugot transmission and I never had any issues with the clutch in that, I was just eager to swap it and now have a NV3500 transmission in place. The master cylinder I am using is as far as I can tell meant for the comanche,

The slave cylinder I use I believe is for a 2000 jeep cherokee 4.0L 4wd. I use a braided hose to connect the two.

Finally to my issue! I have swapped out 4 slave cylinders and 2 master cylinders ever since I did the swap. Is there something wrong with my setup or does autozone just provide crap parts? Please help asap I need a new master cylinder cap and I know they're gonna make me by the whole master not just a cap.

 

**Note** Just so you know if i'm doing anything wrong. I install my slave typically with the retaining straps still on and then I let the pressure break those straps on their own, maybe this is the wrong way to install? Also there is no bleeder valve on the slave and I've read a lot, seems like everyone just pumps the pedal to eternity and I did the same to bleed the system, seems to work for a little while atleast

I just read that the clutch for the nv3500 typically uses dot 3 brake fluid but i've always used hydraulic clutch fluid, possible issue here?

clutch and brake fluid are the same, they are just packaged differently - dot 4 has a higher boiling point than dot 3, and is recommended by some manufactures for brakes that generate more heat- you can use dot 4 in any dot 3 application ( but not dot 5 its a different - its silicone based and is not compatible). since your clutch is not a brake system it would be fine with dot 3 or 4
