bench bleeding brake master cylinder question
This is my first time replacing a brake master cylinder on my 1995 NA Miata track car.
Questions:
1. I'm going to reuse the brake fluid reservoir on the new master cylinder. I see a screw at the base of it holding it to the master cylinder. Removing the screw I assume the reservoir can just be pulled off. Correct?
2. During the bench bleeding process, what do you do with the proportioning valve return line port? Do you cap it during the bench bleeding process or connect a small line from it to the open reservoir like the two pressure lines in the front of the master cylinder.
Thanks Folks!

Well I got it installed. I bench bleed it but I'm sure a lot of fluid leaked out as I reinstalled lines.
What may be a neat trick I read about and used to initially bleed the master cylinder in place was to depress the brake pedal only 1/4 inch and a single bubble will float up in the reservoir from the MC. Repeat till all the air is out.
I'm going to follow up with a two person bleeding drill starting at the the three MC lines,
Thanks Again.
