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:
The Muscle Car Research web site will be down for software upgrade maintenance during the weekend of 15 and 16 October 2011. We should be back online before Sunday evening at the latest.
I've added a few more new products to the store over the past two months:
Things have been busy here recently! We've started exploring what's required to produced brake valve rebuild kits for AMC, GM, and Chrysler vehicles to expand our line of kits. We've also added a brand new reproduction parking lamp lens gasket for 1969 and 1970 Ford Mustangs that is simply the best available on the market today. Here are some links to our recent additions:
Apparently there's a postal strike in Canada right now. As a result the USPS is not currently accepting packages for delivery to Canada. If you try to make a purchase with a delivery address in Canada you'll find that your only shipping option is "local pickup", and "local" means here in Virginia. Sorry for the inconvenience to my Canadian customers, but all should be well once the strike is over and the USPS can again hand off packages to Canada Post.
After being annoyed by a rusty fuel filler door spring on my 1995 Chevrolet Impala SS for ten years or so I finally decided to do something about it. I never had any luck finding a suitable replacement either online or at my local hardware store, so I just had a batch of reproduction springs custom-made in type 302 stainless steel. Here's a shot of the new spring (bottom) compared to an original spring:
