[QUOTE=Purdy Swoft;1699191]Brake adjustment is mentioned in two places in the bulletins . one for the early and another in a different page for the later more common model A brakes . . Without copying the bulletin I'll tell how I do mine . I first disconnect the brake rods at the adjustable clevis end so they will be free and ready to adjust when the time comes . I then move on to the service brake cross shaft adjustment . I disconnect the pedal rod and adjust it so that the plunger at the rear of the pedal rod is 1/16 of an inch from the inside rear of the center cross member where the plunger meets the brake light switch on the 30-31 models . This adjustment is the easy way to set the cross shaft levers pointing straight up and down as Larry Sheppard mentions in a previous post . I then prop the brake pedal at the top of its travel . I adjust the clevis on the pedal rod so that the clevis pin will just enter the brake pedal and hold it at the top of its travel . I then adjust the brakes at the adjustment wedges on the backing plates . I pull back any slack at the front brake levers and adjust the clevises on the front brake rods so that the clevis pins will just enter the front brake levers . I then move to the rear and adjust the rear service brake rods. I pull forward on the rear brake levers to remove slack . I adjust the clevises on the rear brake rods so that the clevis pins will just enter the brake levers. This setup will have all slack in the system removed and the brakes will be ready to activate when the pedal is depressed. If the inner brake parts are in usable condition the brakes will be good .[/QUOTE

Well said and explained Purdy. When you get your drag or wheel individual clevis’s adjusted at that point it’s important to get things pretty even so you don’t have a pull to one way or the other. Even a half turn can make the difference. Road test the car and break them in a little and then adjust as necessary.

Purdy, I’m doing a brake seminar at the 2018 Marc meet. Sure wish you could be there.
All the best !
