Well, The master cylinder that we bought isn't working quite right so you are using the piston and cup out of the new MC and put into the old one. The brakes are working much better. I get a stiff pedal that will stop on a dime but every so often I get a soft pedal that goes almost to the floor but the truck stops slowly. If I take my foot off and reapply the brakes it stops on a dime.
