So last time I posted about this I thought I had a clogged hardline or busted prop valve which maybe I did.

So today I go out and installed a NEW prop valve and a NEW prop to passenger front brake hardline. It was easy and went smooth. So I started bleeding the brakes starting at the passenger rear > driver front and everything was fine. Now I know that on a Civic the brakes are in 2 circuits, one is Pass rear/Driver front, and the other is Driver rear/Pass front. So I think I have some issue with the DR/PF circuit. So what I did was unhook the soft lines and put the vac to it and sucked and it made a slurp sound so I know those lines aren't clogged with anything. Then I put the vac to their hardlines and sucked and got some stuff out but then all it did was build up a lot of pressure and nothing more would come out. I tried pressing down the brake pedal to see if I could squirt fluid out of this circuit and nothing happens.

Here is my brake setup...

NEW Integra MC and JY Booster (but a working one for sure).
NEW Front Calipers
Year Old and not-clogged SS brake lines
Rear Disc Swap with year old Calipers and rotors and all that good stuff.
NEW EX Prop Valve

So what I have narrowed it down to is the MC works but for some reason it is not able to pump fluid to the prop valve, so I think perhaps that line got clogged or something is wrong with it. I think I might go and try and put the vac on that line to see if I can get anything to come out of it.

But any insight would be appreciated.

 

does the MC pump any fluid...without the lines connected??

Did you check if the booster rod is making full contact with the MC rod?

 

I can pump fluid with the brakes to the Pass Rear/Driver Front but not to the other one.

If my booster pushrod isn't adjusted right do you think this could happen?

By the way I vac'ed the prop > MC for the circuit that isn't working and all I sucked was air, so somehow no fluid is getting to this line, however it is not clogged cuz no pressure built up.

I'm thinking its the booster pushrod needing adjusting. Anyone want to tell me why so it makes sense to me though?

 

Wait I think I finally figured it out. At work I was thinking about it.

When I push my pedal down with the car off like half way it as if I am hitting a brick wall, it stops. I bet that pushrod is adjusted too far out so its always sort of pressed in even when its not, I bet it is sort of choking off one line. I'm going to adjust that nut and see what happens. I have a good feeling.

There's your problem.
