I replaced the clutch master and slave cylinders in my 73' Hilux and bleed the clutch. Since then the pressure goes out in a day and I keep having to bleed the slave cylinder. No leaks are present in the line and no fluid loss in the reservoir. Anyone out there no whats going on? Thanks for the help!

 

If your sure of no leaks, under dash on firewall? inside the boot on the slave?
if your having to keep bleeding it, then air is getting in somewhere, possibly either the slave or master has an internal leak in the piston and the fluid is being pushed back and forth past it

 

I think you are right, but I just can't find out where...It's got to be somewhere in the master...thanks for your help. I am going to sell this rig in a while but not until I get everything working properly.
