In California, heavies ( especially fleets ) are inspected every 90 days. That's an inspection of all of the critical components. Brakes, steering, tires and rims, leaks, lights, etc. There is no excuse for letting brakes go thin or below specs. If you do think it's okay, let's apply that to air brake equipped school buses. Yeah, I'd prefer the 90 day inspection. Or, how about this, your driving down the road with the wife and kids. You are at a stop and you look in your rear view mirror and see a heavy coming up behind you. I'd feel more comfortable if the brakes on that truck were inspected regularly!
