need help determining if i have a dual bowl master cylinder.

Hi all this is my fourth posting in a month and i still have not gotten my camaro's brakes fixed. The good news is it finally looks like i found a universal prop valve that will fit my camaro, but the only catch is it will only work with a dual bowl master cylinder.

I cant tell what mine is but i think it is dual bowl. When i take off the cover to add fluid it has a line that goes down the bottom of the cylinder but the fluid still goes over the line so im not sure. My camaro is a 1983 Z28 that originally had a 5.0 H.O. if anyone knows what type of cylinder is in mine please let me know as soon as you can i will greatly appreciate it!

Here is a link to a site that has a picture of what my master cylinder looks like.

Re: need help determining if i have a dual bowl master cylinder.

The reservoir design makes it confusing but all master cylinders since around the mid 1960's have been a dual circuit master cylinder. The front section of the reservoir is always larger because it feeds the front brakes of a front disk brake system. With a 4 wheel disk brake system, both sides of the reservoir are normally the same size.
