My JB Weld epoxy gave up on me this morning to my surprise. It held up fine for about 5k miles. I'd like to fix this for good. Is there a better solution than OEM replacement? I'm assuming the hard lines are included with the part.

It appears that the whole assembly is the valve with the 3 hoses attached. I'd like to replace mine too at some point but I'm curious as to how the brake booster connection on the firewall comes off.

I removed it last time when I encased it in JB Weld.

I wonder if anyone here sells this part or if it is a dealer only item?

I had a chance to pull the check valve out for repair. This will have to do until I can get the new part. I'm pretty sure it is all one piece to replace. Not sure which part number it is listed under so here are both that I found:

check valve: 078-133-753 A
hard lines: 078-133-701 P

Hope it helps someone in the future.

Please post when you find out for sure.

I'll probably give the dealer a call this week. Not sure how soon I'll be replacing it though since I do not think it will fail on me again. This time I stripped some solid core copper wire and wrapped the valve similar to a champagne cork cage. Then I soldered the wire together in several places and finally covered it all in JB Weld. The epoxy should hold up pretty well and the wire is the fail safe.

When I talk to the dealer I'll update the thread. I wonder if they redesigned the part with the update? If not I might have more confidence in the one I repaired.

Stubborn, but Happy

Thanks, rskelme! I like your champagne cork solution, and am going to try it myself.
