Default ERA Brake Master Cylinders 3/4 or 7/8 bore?
Hello,

I went to apply the brakes this morning and heard a snap. One of my hydraulic push rods into the 3/4 master broke the snap ring that holds the plunger rod inside the master. I ordered new masters but on ERA575, I had a 7/8 bore and 3/4 bore master from Tilton. The master closest to the center of the car was the 3/4 and the outer master is 7/8. I am curious if people are running their ERAs with 2 masters that are 3/4 or mixed as mine was. The brake pedal required a lot of effort to stop the car but it also had very old brake fluid that needs to be replaced so it's hard to determine which is the best setup. Curious what others are running.
