Hard to find brake system parts
 

I have a 1992 Chevy G20 conversion van. I have a leak in my brake system and it's the Hydraulic Brake combo/monitoring valve. Discontinued. Hard to find. Anyone know where I should be looking to find one. Need a valid part number too. I have come up with all kinds of part numbers but am not sure which is correct. I have contacted a couple of online parts companies and asked for verification that their part will fit my van but waiting to hear from them. Thanks for the help.

Have you tried a cross index with the same part used on chev gmc pickup trucks?
Its just a valve to reduce pressure to the rears, and delay pressure to the fronts.....
I bet its not that different that the pick up one.
Also it may make it easier to find one at a wrecker.

Thanks for the feedback/suggestions.
 

I have a lead on the part from a parts place in Indiana. Will followup on that tomorrow. Hopefully that will be productive.

I will try what you suggested about cross reference and I have started looking at junk yards.

Thanks again.

If you haven't already found the correct part at the yards, check on Cheapest GM Parts - Shop the Cheapest OEM GM Parts, they have a ton of stock and are very reasonably priced.

I ended up getting the part from a junk yard online. Used part. It worked.
