    Anyone have an idea of the correct length for a 1973 t150v rear conical hub actuating lever ?

    Since I brought the bike just over a year ago I haven’t been overly impressed with the rear brake, the actuating lever is past 90º to the vertical and therefore I assumed well worn shoes. On inspection after strip down it became obvious the lever has rotated further than normal and is almost seized, I am arranging for the shoes to be relined but I do wonder if the actuating lever is too long, compared to the manual and parts websites. All words of wisdom gratefully accepted.

    I’ve just measured mine, roughly, at 4 1/2″ overall length. It’s very awkward to get to so couldn’t measure between centres with any accuracy, but hope this helps.

      Thanks John, mines about the same. I guess the illustrators just use  generic image of a lever in the books, hopefully  a new set of shoes and  clean up will sort it out.

        From the reply by John I assume you have the steel brake plate first introduced in 1974. The 1973 models used an alloy brake plate with an S shaped lever which comes in two different lengths.

        anyway the steel backplate lever is an almost straight stamping. It has one interesting feature – the square hole where it fits to the cam is offset ie not symmetrical. So it is possible to flip this over and change the angle the lever sits at. Check yours is correctly mounted as your description implies it is the wrong way round.

        Good luck!
