I have a 93 Taurus that has gone through 3 rear brake calibers in 1-1/2 years. Two on the passenger side and one on the drivers side. They all start leaking around the main caliber boot. I've replace both soft lines that lead to the calibers also. (Believing that the inside of the hoses my have become delaminated causing pressure to stay applied to the breaks) another issue is that sometimes the breaks are engaged (slitly) on side or another. Its like the pressure from me pushing the break pedal does not release right a way. I'm not sure what to replace next. Does any one have any ideas?

Try This:
BRAKE PRESSURE CONTROL VALVE Sable & Taurus Sedan 1. Raise vehicle on hoist or alignment machine so vehicle is at curb height and wheels are on flat surface. Loosen adjuster set screw. See Fig. 1 . 2. Cut a piece of 3/8" (O.D.) by 1/4" (I.D.) vacuum hose or plastic tubing .64" (16.3 mm) long, and place on valve operating rod. See Fig. 1 . 3. Ensure adjuster sleeve is resting on lower mounting bracket. Tighten adjuster set screw. This positions valve for normal operation. Remove hose or tube from valve operating rod. If further adjustment is necessary, go to DECREASED PRESSURE AT REAR BRAKES or INCREASED PRESSURE AT REAR BRAKES headings below. Decreased Pressure At Rear Brakes Ensure suspension is at curb height and wheels are on flat surface. Loosen adjuster set screw. See Fig. 1 . Move adjuster sleeve up toward valve assembly on operating rod to decrease pressure. Every .04" (1.0 mm) movement of sleeve changes pressure by 60 psi (4.2 kg/cm 2 ). Tighten set screw in desired position. Increased Pressure At Rear Brakes Ensure suspension is at curb height and wheels are on flat surface. Loosen adjuster set screw. See Fig. 1 . Move adjuster sleeve down away from valve assembly body on operating rod to increase pressure. Every .04" (1.0 mm) movement of sleeve changes pressure by 60 psi (4.2 kg/cm 2 ). Tighten set screw in desired position. NOTE: Ensure suspension is at proper riding height. Vehicle must be placed on drive-on type hoist or alignment machine. Failure to comply could affect proper operation of braking system.
