Could anyone tell me if improved aftermarket expanding shoe brakes (within drums) were ever offered in period for tge T please? This is instead of the contracting band type more commonly seen.
Early front wheel version was offered by Morton.
Fordowner, May 1917
Morton Internal expanding shoe brake for the front wheels.
As for rear wheels, nobody offered anything there with the small drum of the Ford emergency steel brake drum. That drum and small shoe is too small be have been an effective service brake with mechanical applied action.
ZIM offered a low cost version, and others, that incorporated Ford's new big 11" rear drum with the fabric lined shoes. That feature works as the Ford 1926-1927 large brake drum is fairly stout. The ZIM kit added rods and an equalizer shaft working off the Ford transmission brake.
There were several different inside lined brake shoes for the rear drum offered. Archer hinged brake shoe, Ferodo, Rush, Channel steel, Stephens, Bailey and as set made by Warford that looks like the expanding type. Not even the Model A had true expanding shoes, they were anchored at one end. See pages 388-392 The Model T Ford Owner.
That's correct for emergency brake shoes.
But question was using such shoes as service brakes, don't know of any yet mfg. who offered rods, equalizer bar, and custom pedal to make service brakes from the std. small Ford rear drum.
The Langbein internal expanding brake, was listed in those pages of the The Model T Ford Owner , but it uses special large drums attached to the rear wheels, and special internal expanding shoes, hooked up to the Ford foot pedal or to the lever. So that is likely the only Ford version of internal expanding made for service brakes.
Appears it needs a special large backing plates, picture is too dark to show, but think these brakes are on a small drum rear axle?
Real Rocky Mountain Brakes use no rods, just a simple cable and equalizer, and the best part is they use the original brake pedal!
Many thanks for your replies gentlemen, most interesting!
