To correctly adjust mechanical brakes, do you place the car on jack stands under the frame and let the wheels & tires 'hang'? This, on a '34 with rods and a '37 with cables. Can some one post the correct procedure?

We raise the vehicle and place the axles, not the frame, on stands. This keeps the rods, or cables, in their correct position and allows turning the wheels to check for drag.

Yes, Bob's got it right, axle stands on the axles. For a routine adjustment, use your hand brake one click at a time to gage your adjustment to even out the drag. I use no drag at the rears for the first three clicks after the front brakes start to drag. That makes it so the rears start to drag at the point where you cannot turn the front wheels. The handbrake makes it easy to get balanced correctly. Alan

My friend Alan knows more about adjusting cable brakes than anyone else I know. For the rod type mechanical brakes, you need to equalize the rod length. Do this by backing off the adjusters on the backing plates all the way, and with all wheels off the ground, and the brake pedal blocked about hald way down, adjust each rod clevis until the lining just touches the drum. Then remove the pedal block, and turn each wheel adjuster until the lining touches the drum, then back it off until the lining is free. Do this at each wheel, but don't touch the rods. If, when you get all brakes ajusted as set out above, you need more pedal, adjust the rod between the pedal and the brake cross shaft. If done correctly, you should be able to lock all wheels in a "panic stop". The secret is in getting all rods equalized, and not using them to adjust the brakes.
