    PV72 - Right Stuff Proportioning and Residual Valves is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Comes with customer service assistance The actual rear proportioning valve is the large fitting nut that screws into the back of the block. This was my first brake system fabrication, so I had to study-up on brake line diameters and the thread pitches of fitting nuts, to utilize this PV block to delete a huge ABS controller out of a '98 pickup. Your purchase comes with some tech support from The Right Stuff, until they get tired of responding to your email questions. I probably reached that point with them, where they wanted to say "you need to hire someone to install this." I utilized a local hydraulic hose dealer to flare custom length lines with the different fitting nuts on each end. I also plumbed in 2 lb residual check valves between the stock Master Cylinder, and this PV. One of my MC outlets was 3/16" line diameter, and so I used the 1/8" NPT check valve as a conversion to increase to 1/4" diameter line into this PV. Brake lines do not handle vibration, so take advantage constraining (read: zip-tie) them to solid objects on your chassis, as much as possible. I put my "ABS fault" dash light wire on the center electrical connector, which grounds out in the event of a front or rear circuit leak. So far I have had no leaks and it slows down the pickup, but I haven't tried to hammer on it to see if it will lock up the fronts before the rears. I still need to bleed some air that is hidden in the lines.

    Rated 5 out of 5 by from Got a old ugly car off my lot We had a 1983 Cadillac Seville (I called it the "worlds ugliest car" sorry if you disagree) on our lot. It needed a new brake proportioning valve, apparently the OE one is now being made out of "pure non-obtainium" because we couldn't get one anywhere. Finally I decided to check Jegs to see if I could use a universal one, well guess what? This one looked and fit perfectly, didn't need any adapters or have to rework the bracket. Bolted her on, bled the brakes, and got that beauty off my lot.
