Location: SW MO | Crosley had American disc brakes first, but like all other things in Crosley automobiles, they sucked too (except maybe the radios). I think that the Imperial/Chrysler disc brake system was the first one that actually worked and was somewhat reliable and along the lines of what we would now term a more conventional system. I'm thinking that posssibly in the late 50's, Studebaker had the 1st conventional American caliper/rotor design, and the '63 Corvette was the 1st American 4-wheel disc brake systems. I just learned recently when exploring the possibility of a disc conversion on my '60 Imperial that the '74-'75 Imperials were the first American car to offer as standard equipment, 4-wheel disc brakes. |

Location: Under the X in Texas | 1949 Crosleys had 4 wheel disc brakes. These were Goodyear /Hawley brand brakes. This is considered the first American true disc brake.
Chrysler first offered the Ausco-Lambert 4-wheel disc brakes on Imperials during the 1949 model year and they lasted through 1955 so while they could have problems under adverse conditions, there were hundreds of sets in service, particularly on the formal sedans and limousines. I had a '53 New Yorker Special that had these brakes optional. Ausco-Lamberts are an aircraft style brake and some do not consider this a "true" disc brake.
The '63 Studebaker Avanti definitely had Studebaker's first disc brakes. They were front only, very similar to Jaguar of the time and in fact also made by Dunlop. I owned an Avanti until a couple of years ago.
Attaching a couple of photos of the Ausco-Lambert Mopar brakes.

No, they are basically drums... just have the brake material press against the front of the drum and not the sides.... |

| I have to disagree....they are discs, albeit reversed from what we see nowadays. When they make that 90 degree bend, they become true discs. |

Location: bishop, ca | Right; these are true disc brakes; it is just that the brake pads expand outward onto discs, rather than having brake pads
contract upon a central disc.
Complicated design, but definitely not drum brakes.

50's Disk Brakes... Glad I don't have this option...
