Narrative:

Dead-headed on a B737-700 aircraft to ZZZ in order to fly [another] flight back. First officer completed walk-around and informed me that a brake wear pin indicator was missing off the right main gear. I called dispatch and was connected to maintenance control. After explaining the problem I was informed; yet again (this is the third time) that any entry on my part would be entered in error and they would not send a mechanic out. After my last brake wear pin report; I received a note from mr. 'X' that I should check my work file. There I found a page of the B-737 maintenance manual (MM) which mr. 'X' had highlighted; proving to me (supposedly) that the brake wear pin can be missing. However; the rest of the highlighted portion states '..then the brake [# 4] can stay in service if the remaining wear indicator pin operation is satisfactory' I have no way of knowing; since those pages weren't included; what a satisfactory operational check is in this particular case; and since it's in the maintenance manual I assume that would be a maintenance function. And as usual; most people here are missing the point. I am perfectly willing to accept an aircraft with a missing pin (even though it is not mentioned in the MEL book) but something is missing from my airplane. Entry in the logbook is required and expected; 'entered in error' is not an acceptable response from maintenance. I am particularly impressed with mr 'Y's comments concerning this when I told him I had spoken with the FAA and they stated that maintenance should come out to be aware the pin was missing. After three reports; I'm beginning to believe the certificate management office (cmo) doesn't care either; so perhaps mr 'Y' is right. Or this would have been fixed by now and it'd be in the MEL book.

Title: A Captain reports his Air Carrier's Maintenance Control has for the third time refused to send out a Mechanic to check the remaining brake wear pin indicator on a B737-700 main landing gear brake. Pilot was also informed if he entered the missing brake pin in the logbook; his entry would signed-off as 'Entered in error' because the MEL does not reference the wear pin.
