And why does it matter, what is the purpose?

My guess is a bit of preload.

Its the only way to differentiate the pads from the left hand set from the right hand set.
Pads are mirrored about each rotor.
(e.g.)
41060-65002 ASSY-BRAKE PAD (M33) RH/LH

Bumps might be biasing the pad during braking application to prevent binding, chattering/squeal, or to ensure initial pad contact area is on trailing side of rotation at rotor outer edge....?
Somewhere hidden in the Dunlop brake archives is the answer for this design feature .

(I'm holding out that the pad arrow might be indicating the way you turn the steering wheel to get access to the caliper for respective pad. :roll: )

Ray,

I believe your reasoning is correct. I've seen this trailing edge bias of new brake pads on the emergency braking systems on large rotating equipment. It increases breaking efficiency and extends pad life.

Adjusted my trunk latch. On my latest trip home from Grand Forks to Kelowna it kept popping open. Stayed closed all day today running around town.
