    “. . . On the planet . . “ is surely a stretch.

    Although newer semi truck trailers are more likely to have air disk brakes, there are plenty of older semi truck trailers on the road today ( and therefore are still “on the planet”).

    There are also still plenty of older cars and pickup trucks with drum brakes on the rear axle.

    Maybe it was too well concealed.

    once the hydraulic actuator receives the electric signal to apply, there is a delay of 2 to 4 seconds.
    As others have mentioned, up to 4s delay seems excessive and that might indicate another issue. Thought I read somewhere that any air in the system could contribute a little bit to the delay.

    Good one. I didn't think about that! If you consider bike rims as discs, road bikes have had discs since .. forever?

    I think some semi-trailers have drums. I'm not sure why the towable RV industry hasn't converted wholesale to discs. I can't imagine there's *that* much cost savings.

    Is there anyone here who knows why the trailer industry seems to have this fixation on drums? I know they're probably easier to install, but so is a hole in the floorboards where you can drag your feet.
