Sorry for my first post being a "for sale" ad. I read the posting guidelines to make sure it was OK. I've got a long history in the Mustang community, but I thought this information would also be of interest to owner of classic Torinos and Fairlanes.
I recently got all of the needed parts to offer a rebuild kit for the Kelsey-Hayes brake pressure differential valve used on certain 1970, 1971, and 1972 Ford and Mercury vehicles equipped with front disk brakes. Here's a link to see the details and place an order:
D0OZ-2B257-C Kelsey-Hayes Pressure Differential Valve Kit D0OZ-2B257-C Kelsey-Hayes Pressure Differential Valve Kit - $25.00
This valve was used on the following cars equipped with front disk brakes:
1970 Ford Mustang
1970 Mercury Cougar
1970, 1971 Ford Torino
1970, 1971 Ford Fairlane
1970, 1971 Mercury Comet
1970, 1971 Mercury Montego
1972 Ford Pinto station wagon
I should have a similar kit available for 1968 and 1969 vehicles, sold at the same price, in a few days.
