    Well golly I guess I'm busted. I get Castrol DOT 4 when it is available
    but any DOT 4 when Castrol isn't handy. Used to be the Brits used
    natural rubber as a result of it being available from their colonies.
    Their colonies gained independance and the Brits started using synthetic
    rubber components like the rest of the world.

    The generic DOT 4 seems to be OK with the syntheric rubber. If you are
    running real old brake components or rebuild components with parts left
    over from the sixties or so you may have problems not using LMA.

    Notice I have never suggested DOT 3.

    Next time I rebuild the Green Rover's brakes I expect to go over to DOT5
    and leave the LMA or not LMA question behind along with the corrosive
    brake fluid that absorbs moisture.
