Hey, It says that the unit comes pre-bled from GM. Here is my dumb question. When I install this do I need to bleed the whole system or just remove old, install new and go? I'm only replacing the master at this point. Thanks

 

I did the master and slave at the same time, but the master did have fluid in it and was supposedly already bench bled. The slave however was dry. I hooked up a motive bleeder with a slave extension and bled all the air out. I think you'd be ok but it shouldn't hurt to bleed it.

 

Since the system uses a quick disconnect fitting between the master line and slave cylinder, technically it should be ready to go after installing the master cylinder and attaching the line to the slave.

However, I'd bleed it afterwards just to be sure there is no air trapped anywhere in the system.

 

Okay, thanks for the help guys!
