while trying to bench bleed my dual master cylinder i noticed after bleeding out the air that the rear was pumping out a normal stream of brake fluid but the front was not pumping brake fluid. while trying to bench bleed the brake fluid in the rear reservoir was getting pumped into the front reservoir. bad or missing seal?
the parts store tried to tell me i did not bleed it correctly. i wanted to tell the guy that i have been bench bleeding master cylinders before he was born. i don't like the new way that the parts store wants you to bleed them. i have another one on order. the guy told me that if the same problem occurs again he is not going to honor my warranty. i would like him to try that. he will be very sorry.
