Hi Folks, http://www.projectchevelle.com/miscImages/11_30_03_misc-brake.jpg
I am not too sure of what this part does; it looks like it has a terminal on the top of it ... Could that be where the brake level warning light connects to? Is that also a proportioning or combination valve? And if it is, would it be on a car with all four drums? Was there such an option as power drums? Thanks!! -Graham.
