You should know that I edited/created that page (JohnZ wrote it), and I *still* didnt' remember that I need to depress that plunger. So thanks for bringing this back up!

Hi guys, first of all, I hope all of you are taking care and keeping safe with all of this virus stuff around!!

I know this is an "old thread" but I'm hoping that some of you might still be getting notifications when someone posts here. I have a '69 Nova SS with drums in the rear and discs up front, all stock. Here's my dilemma.....I had been experiencing a low pedal for awhile so, even though I had the whole system rebuilt about 10-15 years ago, I decided that maybe the master cylinder was at fault. I brought it to the guys who rebuilt it (they sleeved the master, wheel cylinders and calipers with stainless back then) to have them redo the master. They said it really didn't look that bad but put in a new "kit" anyway. I started the installation yesterday, bench bleeding the master, installing it and then proceeded to bleed the whole system. I'm using a "one-man" vacuum pump style tool. I was doing pretty good until I got to the front brakes. Very little fluid (I thought) was coming out from the passenger side caliper. When I started on the driver side, nothing was coming out!! I even took the bleeder screw out of the caliper completely and stepped on the brake pedal. Still nothing, not even a drop!! Then I remember searching different sites for pointers on bleeding brakes and ran across this thread. I called the brake guys and mentioned the plunger on the metering valve to allow the fronts to be bled and he said that it shouldn't be necessary. He said to just start checking for a blockage. The first thing I did was disconnect the metering valve. When I tried to push in the plunger it wouldn't budge!! My question to you guys is, how much pressure does it take to push that in? Also, in normal operation, does that plunger go in and out every time you apply the brakes?? The reason I'm asking the question here is, I'm having a hard time getting a call back from the brake guys right now. Thanks in advance for any help you can provide!!
