I see said the blind man as he picked up his wheel and spoke
I've always used pad for the piece that contacts the disc or drum and shoe for the whole piece, but I know that some people use the term pad for discs and shoes for drums. My bad.
Of course I'm not alone
:
From a website of legal definitions:
"Pressurized brake fluid travels along the brake line to the caliper. The pressurized fluid pushes the piston (green) and inner brake shoe against the disc (blue). Pressure against the disc pushes the caliper away from the piston, pulling the outer brake shoe against the disc. As the brake shoes clamp together, friction slows the rotation of the disc and wheel. "
and from the Muscle Car Clubs website:
"Brakes, Disc: A type of braking system in which brake shoes, in a vise-like caliper, grip a revolving disk mounted on a wheel to slow or stop disc and wheel rotation for braking. Properly called "Caliper Disc Brakes," they are used on most modern cars."
