rebuilding caliper question

Rebuilding calipers on a 65 327

Which way do the piston seals go when putting them on the caliper piston?

The seal has a groove, groove toward the pad or the other way?

Thanks

Jim,

The sharp outer edge of the seal points AWAY from the brake pad. In this way, fluid pressure behind the seal increases the pressure on the sealing surface. If installed the other way, fluid pressure would easily pass by the seal.

I still dont understand which way. The seal has a groove in it, which way does that point?
