Bleeding the brakes yesterday and noticed no fluid coming out of the front left brake line. Started investigating. The problem seems to be here (see pic)


Where the RED arrow is pointing there is no brake fluid coming out. Reviewed the Haynes repair manual. It's a Combination valve. "Note: The combination valve is not repairable and must be replaced as a complete assembly" Is this info correct? Can anyone else provide feedback?

Thx

in your pic you are missing a line coming from your master cylinder to the valve. Was that already off or did you take it off when trying to diagnose the problem and just snapped the pic afterwards?

I removed the line during the diag to confirm it was not clogged.

yea I don't know where to get one. I had to get one from a member here who found one in a boneyard. I had a fitting go bad on my original, so if I can find the other one, you can just have it. Give me a couple days to locate it, I would try to source another one in the meantime in case I can't find mine.

And here I was thinking this was going to be a budget brake swap thread.

Thanks Shaun but I'm actually going to part out my '88 notchback (keeping parts for replacement). Just was curious if anyone has dealt with this. Seems to be non-repairable.

O sorry about that typo in the TITLE.

There's *nothing* on any car about which that is true... they just didn't take it apart to comment on it... FAIL.

'scuze you, that came out a very nice 88 4 cyl with the doors falling off in a friends driveway.

FGT if you need one I have more.

How about just taking your current valve apart and cleaning it out?

There's a write up on the web somewhere in which a guy milled away half of one of these to show how it works.

One of the guys on CFF posted this link:
