Bleeding brakes

I was bleeding brakes on 1994 nissan pickup and the bledder valve twisted off on the rear wheel. What do I need to replace to fix the brakes.

Greetings colk welcome to the Forum.

Two ways to do that....

First...
You could try to use what we call an "Ease-Out". Looks like a course reversed screw that you tap into the hole that's in the center of the Bleeder, turn it counter clockwise, and hopefully the remainder of the Bleeder will break free, where you can extract it, and replace it with a new one.

However...
That hole in the Bleeder is real small, and given that you broke the nut part off either tightening or loosening it, you might just break the Ease-Out off too.
If you do, then the other possibility is about the only thing you can do.

Second....
Replace the Brake Cylinder.
(which may be the easiest way to get this done up front)

Have a good Day !

SWH is correct that since the bleeder snapped of a Easy-Out will most likely break inside the bleeder hole. I would recommend a revers drill bit that is not to large that it drills out the threads just the metal bleeder. Sometimes with the reverse drill bit it snags the broken piece and removes it but if it doesnt you can pick the bleeder threads off the slave body.
