Slave Cyl Bleeder Valve
 

2013 Fiesta SE slave cylinder bleeder valve. I think I found the bleeder valve on top of the bell housing. It looks odd. Is it plastic. What is the procedure for opening the valve? I have bled slave cylinders on brakes for decades, but this one looks unusual. I do not want to break it. What is the procedure for opening it? What do I have to remove to get access to it?
