I'm at near 20k miles on my original brakes. I have a TT, but it scales at around 9200lbs loaded (has an 11k lb GVWR. I think next year I may flip the shoes front to back. The way magnetic drum brakes work is you only use one shoe when stopping going forward, and the other one when stopping in rev. So my shoes that only work in rev still have 90+% life on them. Car/truck drum brakes use both shoes however!
:h
Drums have primary and secondary shoes, the secondary being smaller (less lining area, BUT they all work during braking either direction.
The brake shoes only have one FIXED anchor point. so when the are activates the primary shoe, it pushes the secondary shoe into contact also.
Thanks to Mitch150 for the great photo!!!
Ok guys. You may want to look at that photo again! When the magnet swings in the pendulum it's only pushing one shoe out, depending on which way it moves. Look where the pivot is and where the lever is for the shoes. Only one shoe will react to the magnet/pendulum at a time. These aren't hydraulic drums that push on both shoes!
