    the brake prop valve is just like pneumatic (compressed air) adjustable valve !want more pressure screw the adjuster in,less out . You do not want your rear brakes locking up before your front brakes or you are along for the ride

    I installed a Cadillac rear disc kit for my '73, then installed a '80 Corvette master c/w a Summit adjustable prop. valve that adjusts the rear. Works awesome.
