Re: Brake Booster working TOO much
Not sure but on some vehicles the diameter of the master cylinder piston is a different diameter on a disc brake set up vs. a drum set up.
made that mistake before, 15/16th dia. vs. 1 inch dia. makes a BIG difference and you feel it right away with a power booster
disc brakes usually have the larger diameter piston because disc brake calipers require a larger VOLUME of fluid to opperate
