Riding style is going to dramatically affect pad life. I assume to get 33k you're not doing a lot of braking... Distance touring, perhaps.
I get about the same from my front pads. My rear seems not to be wearing. I asked the dealer to re-bleed the rear. I am not sure if they are working that well. I am going to re-bleed them this spring
I just score 2 sets of fronts for $35 each. new old stock on ebay. But the fronts can be found for $42 on ebay. I go through a set of fronts about every 3 years or 35k ish miles. Ive never changed the rear. Probably the original with 62k miles on them.
