I just installed a clutch and presure plate. Now i have no clutch at all. I'm guessing i have to bleed the slave cylinder but i dont know where to start to do that.. Any Help would be great.

 

Fill out your sig, what year truck, etc?

Is the slave cylinder internal or external?
If it is external there is no reason to brake the lines so there shouldn't be any air in the line.

Usually there is a bleeder, like on brakes, so you would need to pump the pedal and bleed it just like brake system. I have had luck with pushing the pedal in and holding it on the floor with a stick or something, then open up the bleeder and just keep filling the resevior with fluid.
