Ken is right about the radius of new shoes not matching worn
drums. I put on new shoes and new slave cylinders on my camper
several months ago. My pedal simply was sloppy and no amount
of bleeding could fix it. I ended up double pedaling always.
That means I stepped on the pedal twice and the second time I
do it the pedal would be higher and the brake would be fine.
The Pedal wasn'r spongy so it wasn't air in it. I knew it wasn't
right but I could not fix it by adjusting or bleeding.
Somehow a few months later now suddenly the pedal is right.
I no longer need to double pedaling. I think what happens is the
shoes are worn to a point that the radius now matches the drum.
And the self-adjust is kicked in correctly.
I should have filed the shoes when I put them on. It took me
several hundred miles to break in instead. Of course I am not
an expert and I could be wrong. Bottom line is my brake works
correctly now and it has been that way for several weeks.
