A buddy has an early 28 phaeton the front drums are shot ,badly scored .The vendors only sell the later "wide" drums not to suite AR wheels . Can he have these drums turned down to fit the wheels ?

yup snyders lists them.

turning them down may not help as the Hub it attaches to is different as well. and you would have to use the later profile wheels.

an inquiry re. a used one may be the only answer. or

i am editing out this reply on using a newer style baking plate as that was hoky. you would have to change both hubs, both drums, both front wheels. to do that .

I've heard of folks putting liners in drums but the old stamped steel drums are pretty thin. I'm not sure if Randy Gross has AR type cast iron ones but his service put's new drums on the old hubs with swaging as original. They then turn them true. His drums are a bit undersize to get them back to new specs. They take longer lug studs than the originals but that stuff is available along with a swaging tool.

Mechanical brakes take some work to get them right but they function well enough when they are properly fitted and well adjusted. A person can arc their own shoes if they're equipped well enough. Doing it by hand is a lot of work but it can be done that way. Just use modern non asbestos linings.
 
yes park brake works the front and the bake at the same time. on the early model A (in north america with the left cowl brake handle). pull that handle and all 4 brakes come on
there is only one rod to the back brakes.

We just installed new cast drums on an AR using the original hubs. The front was no different and the rears were upgraded to separate parking brake. No other changes.

In my Snyders catalogue with the blue 28 roadster on the front the AR hubs are not listed . Snyder does have an agent here in UK and the hubs are en route . Thank you all .

The early brakes had a special equalizer set up to use both service and e-brake for the same shoes. It was kind of complex for it's time. The new government regulations came out to require a separate e-brake system so Ford had to change it.

The change over was a state requirement - and imposition was done on a state by state basis.

Ford, however, changed ALL production over to an E-Brake separate system in case the states continued to "tighten" around the requirement.

Judging standards indicates for cars the Ford change over to a dual system began in February 1928 and was completed by June 1928. For trucks the change over was not complete until early 1929.

State requirement. NH never imposed the requirement hence a July 1928 AA truck in my garage in the early style.

But owners COULD have a solid cross shaft (it has a "bend" to fit around the drive shaft) should it be required (i.e. brake rod changes/cross shaft ends) or their state required it. (p. 259 Service Bulletins)
