    Just a heads up, had my rear brake lock on going down hill off camber which resulted in a dislocated shoulder and bruised ribs (my shoulder pushed into my rib cage).
    The culprit was a broken shoe spring that jammed the brakes on.
    The spring had some corrosion and was snapped off at the point where it goes through the hole in the shoe.

    Jo,
    Hope you recover quickly and can get back to riding very soon. Thank you for reminding the rest of us to keep safety in mind when looking over the worn parts on our vintage bikes.

    Put a tad of white brake lube where the spring goes through the hole in the shoe. It's a high temp brake grease we use on the back plates we're the shoes ride on cars, trucks. I lube the cams on dirtbikes too.

    Wow! Never heard of this before. Bill's recommendation sounds like a good one I'll be practicing.

    Can't say I've ever lubed as bill describes, but it makes sense. I've certainly seen springs in the past with a wear indent in the described area.
    Thank you for the reminder about the risks of these older bikes. A "Fix to ride" can still mean picking up a lot of new parts.

    ive always dabbed a bit of grease on the cam surfaces, but springs are springs. ive seen the holes elongated and the spring hooks worn a bit but ive never heard of them breaking as the shoes are alloy and the springs steel. its usually a one sided fight. but these areas get dirty and hot cold hot cold and are used heaps more than road drums.

    While taking apart old Huskys for restoring or parts I have on several wheels over the years seen damage inside the hubs showing signs of broken springs or spring that come loose. You usually see the damage on stiffening ribs that have chipped or broken.
