  • Brakes: 532252 no-rol and a 1552294 no-rol?

    What is the difference between the valves used in these two No Roll kits?

    A SWAG would be the material used for that grommet the ball seals against. Luck Doofus

      The only difference I see is the control levers are different

        I should have asked if the valve itself was different.
        Doofus explained that the internal seal was a different material.
        It seems to me that the valves themselves would interchange.
        Am I correct?

          When I opened the two and compared them the valves themselves look the same

            I am only making a SWAG here.old time brake versus newer formulas might need a change in rubber formulas. when the National Guard switched to Silicone fluid it was a total disaster,all the hydrovacs had to be replaced and most wheel and master cylinders had to be replaced. the supply system was unable to meet demand for new stock and rebuilding went into high gear. through the official grape vine we heard the old rubber compounds werent compatible with new fluid like someone thought! I still have nightmares of pallets of wheel and master cyilnders waiting to be refurbished. Luck Doofus
