These things are dang near impossible to bleed in the truck. Matter of fact, they aren't designed to be hand bled and do not have a bleeder valve. You are actually supposed to buy the whole thing, master+ slave which are normally pre-bred by a machine.

Now it can be done. I've replaced several and about the only way you can bleed these things it to remove the master and slave both from truck When removing the slave, be very careful not to shoot the push rod out of the slave.

From here on, you will need 2 people for this, counting yourself, brake fluid, a small 4in block of wood and a vise and rags. One it is out, make sure the line from the master to the slave is connected, put slave gently in vise, have one person hold the block of wood to the pushrod of the slave cyl and with the other hand, they need to hold the master cylinder level above, fill master cylinder with brake fluid, now go and work the master cylinder actuator, as you push, the other person should apply gentle resistance to the slave pushrod while allowing it to move( they can use the block of wood to push against as it is more comfortable on the hands but its not required), once you have it depressed all the way, make sure master cylinder is full of brake fluid, then have the other person push the push rod back in as you apply resistance on the master cylinder actuator. Repeat over and over until you see no more bubbles in the fluid in the master cylinder.

Don't be surprised if this takes an hour or more, its very hard to bleed without a bleeder valve.
