A customer recently asked me if I had a rebuild kit for the Bonaldi proportioning valve used on his de Tomaso Pantera. I didn't then, but I do now! As usual, I've also written articles that describe how to disassemble and rebuild the valve. Here are the links:

I've just completed the research necessary to provide a new seal kit for 1970 - 1976 Mopar brass combination brake valves made by Weatherhead and Kelsey-Hayes. These valves were used on 1973 - 1976 A-bodies and 1970 - 1971 E-bodies. There are undoubtedly other applications, so please contact me if you know of any that I've missed. I've also added rebuild instructions to my library of technical articles. Here are some links to the articles and the seal kit:
Please note: Due to pressing commitments there will be delays in order processing from March 24 through April 6. Orders received between those dates will be processed in batches during the weekends of March 31 and April 7. I apologize for the inconvenience, but please plan accordingly.
During the 1970s and 1980s Kelsey-Hayes supplied a cast iron combination (pressure differential, proportioning, and metering) brake valve to all of the major domestic automotive manufacturers. Here's an example that I removed from a 1979 Camaro:
I've just added a new rebuild kit for 1967 - 1975 GM brake pressure differential valves to my inventory! I'm still researching the original applications, so please feel free to contact me with questions, corrections, or additional information if my descriptions are incorrect or incomplete. Here's a link to the kit:
and a link to a pair of technical articles that describe disassembly:
I'm finally having some success with my research into the brake valves used on Mopar and GM vehicles. I've just added brake tube tee (that's the Chrysler term for the brake pressure differential "valve") seal and spring kits for a number of 1967 - 1975 Chrysler corporation vehicles. Though several different valves were used as far as I can tell they all use the same basic internal parts. Here are some links to the kits:
I'm still working on a major upgrade to the underlying software used to make this site work. I believe everything is functional, but I'm still working through some display issues, including:
