Ronnie Posted September 4, 2021 Share Posted September 4, 2021 Contact Jim Finn. reattas60@gmail.com Jim has been selling used Reatta parts for years. He might have the part you need. Link to comment Share on other sites More sharing options...
2seater Posted September 4, 2021 Share Posted September 4, 2021 They have been unobtainium for years and Jim has been a very good source for me too. One other word on the part itself. I have done three replacements of rear brake lines now, and despite the crusty appearance of the valve, once it is removed, I place it in a vice and then use whatever means necessary to remove the fittings and they have always been pristine inside. I also relocate them but that is a different matter. 1 Link to comment Share on other sites More sharing options...
Padgett Posted September 4, 2021 Share Posted September 4, 2021 Back when I was road racing Corvettes, one of the first changes was to an adjustable proportioning valve to be able to tune the brakes, They are still around. Link to comment Share on other sites More sharing options...
ship Posted September 5, 2021 Share Posted September 5, 2021 The GM part # is 25525844 and was used on E body autos (Olds, Caddy, Riviera, Reatta) during years 88 thru 90. You might find one in a junk yard. 1 Link to comment Share on other sites More sharing options...
