Bleeding Clutch

Well a friend of mine and I dropped the transmission last night to fix a leak. We ended up replacing the slave cylinder and a new clutch set. Once we finished everything we went to bleed the line for the clutch and we can't get the damn thing to work. We let it gravity bleed for about 2 hours, and tried doing it the way the repair manual says and still no pressure. Are there any tricks to this or something i'm forgetting?

Truck specs are in my sig.......4.0

try using a syringe or something were you can pressurize from the bottom and push the fluid up and through the slave. sometimes that is the only way to get the clutch pressure back because the slave can trap air in itself

sounds good. thats the way i have to bleed the slave on some of the older (2006) volvo transport trucks. the slave is mounted in such a way that they fill with air at the top and can only be bled from the bottom

There could be air trapped in the line between the master cylinder and the slave if the fluid drained out after you disconnected the slave.

Well, we started bleeding it again last night, and we disoconnected the line from the bleeder and the fluid was coming through with no air, which made me realize that the slave was probably bad, come to find out Smyth Automotive sold me a defective slave, so we have to take everything apart again. It was sketchy bc when I got the slave the box was all crumpled and had been opened, so i'm thinking it was already returned once so they boxed it back up and sold it to me
