Brake pedal grease fitting?

Is this really a grease fitting - like a zerk, without the little ball bearing that holds grease in once it's injected - on my rear brake pedal? Does it really work? I would think it's more effective to simply slide the pedal off (the fitting is also the bolt that holds it on) and grease the shaft, but I imagine this is here for a reason. Never noticed it before.

Grease and go. No tools needed.
