Wirewizards, Its ironic I just bled and adjusted my brakes on my 52 Good Humor Truck today.I started with all new system, lines, master cylinder, wheel cylinders,shoes etc.I justed the shoes alittle and started adding brake fliud.The pedal kept going to floor sense there was no fluid in the lines and the new wheel cylinders, it took awhile.I would bled the wheel cylinders intill I got all air out of the lines and then readjust the brakes shoes.I did have two small leaks, one was the rear axle flex line .Just needed acouple of copper washers.Bill and Carl right.
