i have the standard clutch hydraulic slave, lakewood bell hsg and ram clutch. i hooked up a pressure bleeder to the clutch master cyl and pumped it to 20 lbs. the fluid got to the exit fitting on the mc ( i know because it leaked) but i get nothing at the bleeder. i even cracked the line going into the slave and nothing. before i start checking the lines and unions for blockage, am i missing something?. shouldn't 20 lbs push fluid through even though i have the tank set below the mc? does the piston in the mc have to be in a certain position to allow fluid to pass through?.
