Hello, everyone. My '91 Aero XL as developed a brake fluid leak on the back side of the combination/metering valve located just below the master cylinder. The leak is coming from the rear of the valve...see arrow in pic. Is there a way to repair this problem, like replacing an O-ring, or do I need a new/salvaged unit to fix the leak?


Thanks for any info on this part.

 

From what I've been able to find out, the part isn't necessarily repairable.
Raybestos makes one and calls it an ABS modulator valve. Amazon has it for around $90, but takes 2-5 weeks to ship. HA!
I might have to go to a u pull it yard, in that case. The local Ford dealer told me the part was no longer available.

It is the plug on the rear. I might take it off to see what I can do with it. I've located one in a local salvage yard for $45.
Thanks for your feedback. If I find I can stop the leak myself, I'll post the process here.
