the model T to 1926
The front axle was drop forged as a single piece of vanadium steel. Ford twisted many axles eight times and sent them to dealers to be put on display to demonstrate its superiority. The Model T did not have a modern service brake. The right foot pedal applied a band around a drum in the transmission, thus stopping the rear wheels from turning. The previously mentioned parking brake lever operated band brakes on the outside of the rear brake drums.
in 1926 the braking system was upgraded
For 1926, Ford widened the transmission brake band from 1.125 inches to 1.75 inches, providing it with both greater stopping power and substantially longer life. At the same time, the emergency brake drum was increased in diameter from eight to 11 inches and lined for the first time with asbestos.
Until then, what braking action the device provided — and it wasn’t much — had resulted from unlined iron shoes pressing against steel drums. Brake and low-speed pedals were widened and supplied with a lip to prevent the driver’s foot from slipping off.
In 1918, a young inventor named Malcolm Lougheed (who later changed the spelling of his name to Lockheed) applied hydraulics to braking. He used cylinders and tubes to transmit fluid pressure against brake shoes, pushing the shoes against the drums. In 1921, the first passenger car to be equipped with four-wheel hydraulic brakes appeared — the Model A Duesenberg.
Carmakers as a group were not quick to adopt hydraulics. Ten years after the Model A Duesie, in 1931, only Chrysler, Dodge, Desoto, Plymouth, Auburn, Franklin, Reo, and Graham had hydraulic brakes. All the others still had cable-operated mechanical brakes. In fact, it was not until 1939 that Ford finally gave in, becoming the last major manufacturer to switch to hydraulic brakes.
The basic braking system we have today was pretty much in place by 1921, including a refinement some regard as contemporary — power assist.

Model T’s were not made in the ’30’s
Most cars made in the ’30’s had hydraulic actuated drum brakes on all four wheels, though there were some with cable and/or rod actuation.
