FWIW

There is hard bonded and soft bonded, the soft bond you can feel a slight depression with your thumb nail. Soft bonded will work with mechanical brakes and steel and cast iron drums.

Hard bonded will only give you adequate braking with a hydraulic brake system.

How do I know, well on one of my previous brake jobs, I never could get any decent braking. After tearing the system apart and checking the arcing and centering to find nothing wrong I had discussions with club members and was able to determine that the brake shop installed hard lining. I obtained some soft bonded brake shoes, arced the shoes to the drums put everything back together with no other changes and I have BRAKES!!!
