New Bonaldi Brake Valve Kit for 1971 - 1974 Pantera

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:

New Mopar Brake Valve Kit and Rebuild Instructions

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:

New Mopar Products for December

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:
