Did you have a leak to the rear before this?

Have you tried cracking the line to the fronts on the master, then have someone push the pedal slowly down hoping for that click to recenter it?

Yes, I'm performing a rear disk swap. So the rear lines were completely disconnected.

I have tried pumping the brakes with 4 different lines cracked, nothing moved the plunger. I wasn't exactly sure which line to crack. The M/C line on the opposite or same side as the plunger? Or the outgoing lines to the brakes, and on the opposite or same side as the plunger?

Thanks,

I'm not sure exactly, but I wouldn't think it should matter as long as the rear circuit pressure overcomes the front. But I could be completely wrong, it wouldn't be the first or last time.

 

The valve doesn't care if the engine is running or not, but vacuum assist might help.

 

Nope. I attempted front/rear (separately) on the M/C side and front/rear (separately) on the Brakes side, with and without engine running. The plunger has not moved.

I'm starting to think I need to see what it takes to remove the whole unit so I can push the plunger with a screwdriver.

Can you get good fluid out of the rear line at the master?

 

Yes, I get fluid out of both lines out of the M/C.

Thanks,

I'm wondering if the process isn't working because my rear lines don't have any fluid. Maybe cracking the front lines doesn't give it enough pressure drop since the rear lines are full of air? I'm thinking about trying to figure out how to fill up my rear lines with brake fluid so I can try the process again.

Thanks,

If you have access to a Motive type pressure bleeder you could fill the lines by reverse bleeding. Connect the pressure bleeder to the caliper and crack the line at the MC. If you don't have a Motive they're easy to build. Watch YouTube videos for make a pressure brake bleeder and reverse bleed brakes.

I ordered a Motive pressure bleeding kit today.

I also heard the suggestion to plug the rear line port on the PV, crack the front line and attempt to move the plunger that way. I don't have a plug immediately available, but it's another idea I heard.

Thanks,

Did you ever figure it out im having the same prob on my 2002 s10 can't get any fluid to rear brakes please help

 

@jonshoeshack If you haven't already, I would start a new thread. I don't think anyone in this thread has been around in almost 2 years.
