Wow never seen that before , you would have thought if that was from new it should never have got pass quality control, good job you found it and rectified it tho, interesting video Simon

I’m always transfixed by your maintenance videos. You always explain things so well and make every job look do’able to the average Joe!

Thanks. I find making the videos helps me too, as it forces me to slow down, be systematic and to rationalise everything I do.

Very useful thanks

Great job, Simon. I must admit I have never seen a master cylinder crack like that.
But HD do mount them in some peculiar places. Barnies 96 dyna exactly the same place. Is the rear brake light switch still incorporated in the brake line. Top man, nothing better than songs from the saddle with my first cup of coffee ☕️

That is caused by Galvanic Corrosion, Two dissimilar metals. See it a lot on old Land Rovers where the aluminum door skins react with the steel frames the corrosion after time pops the aluminum door skin leaving a white powdery trace,

Thanks for that. Seems like the logical explanation.
