Brake Adjusting Shaft A-2042
 

How critical is the length of the brake adjusting shaft A-2042? I would think that both sides on each backing plate should be equal, so what would be an acceptable variation in length?
I plan to use woven linings that are bonded to the shoe, is there any history of the bond not holding?

They should be the same length.
For some reason the 'pointed edge' (really the forging line where the 2 dies come together) is usually worn down making it hard for the adjusting cone to 'click' properly.
I usually dress the 2 slanted surface on a grinding wheel. At the same time i use a dial caliper to check the length and grind as needed so that I have pairs of equal length; else you will not have even application of the shoes. A very easy task actually.

Not sure how well the bonding process would work with woven linings. Why take a chance? Riveting them on is not hard, and works very well.

I've never seen a bonded shoe come off while a car is in service, but my Corvair was parked for a year or so and the bonded linings came off.

Anyone know the factory tolerance on the length of the brake adjusting shaft?
