asilverblazer My boosters make a huge difference,if you climb on the brakes it will squall the front tires and you have pretty good control of the truck. Now I told you about the bendix vaccuum cylinder oil ?? If not get hydraulic jack oil,same thing-Carters told me,that leather cup in the booster gets dry and needs 2 ozs. of that a 2x a year that is on a bendix booster 1951. Midland may be different.
