Upon an attempt to flush my brake system and install new synthetic brake fluid back in late Nov, I had come to the conclusion that my master brake cylinder was shot because I could only get pressure in the second stage after my first try (brake pedal almost to the floor) and with the weather closing in, I decided to let it go until the weather broke. In the meanwhile, I had ordered a new master cylinder, about $100. I installed the new unit the other day only to find out I still had no pressure in the first stage
I followed every direction I knew, and advise from fellow members here, so what the hell am I doing wrong,

I mumbled to myself!

I read the 124 bible again, nothing I had been doing was wrong. I filled the reservoir and connected up my mity-vac to the right rear wheel and pumped away....nothing. I disconnected the hydraulic tube from the master cylinder and put it in a jar filled with fluid and then pumped some more and then I started to get the fluid running out the right rear.
I remembered several people here mentioning not to over look the rear portion of the reservoir and to make sure it fills too. (there is a dam between front and rear of the reservoir) because it had been empty it appeared full.
Well, it wasn't!
The rear section of the reservoir dam represents what appears to be 1/16 of the total volume and it will not fill unless you rock the plastic reservoir back and foreth and watch for bubbles at the top as it fills in.
I wonder how many people have done the same thing?
