I use an infrared thermometer to adjust my 35 Phaeton brakes. I drive it a while and then measure the temperature of the drums. If one it too hot I loosen it. If one is too cool I tighten it. When they are all about the same I think they are adjusted about right. Jim in San Jose.
Yes, just like the rear brakes, both shoes will move outward at the bottom when the brake pedal is depressed. That's the function of the wedge 68-2050 shown in #19, namely to force the rollers at the bottom of the brake shoes outward taking the brake shoes with them.
A 7/16" eight point socket is a good substitute for one of the original special purpose adjusting wrenches.
