Default Rear brake pad lifespan?

Today I changed out the rear pads on my 2015 f-sport AWD, I was surprised to find out that like at least 65% of the pad material was still left on the pads (although it appeared the inners took more abuse than the outer pads) and the car has 50K on it. I did the fronts at about 40K? (maybe it was more I forget, I know the car was over 40 when I did them) last fall and those things had maybe 20% left on them at the most. Those were the original screechy 2015 pads that squealed like mad when cold... I am using current OEM pads now.

What are other people seeing for pad life on these cars?

There was so much left on mine I was like WTF. I almost didn't do it, but then by that time I had the wheels off already and I'm like... I went through all that... eff it, I'm just swapping em.

Front brakes take ~70% of stopping energy. Of course the front brakes are usually larger in surface area, but fronts wear at a much higher rate than rears...

Yep when I replaced my rears last year the outer pads were still good but the inner ones were way past done, so bad that the inner rotor was wavy.

I think this is starting to change with a lot of manufacturers. In my Infiniti the rear brakes wear much faster than the fronts, and I'm told by the Service Advisor that it's because the car uses electronic brake proportioning - essentially the ABS system tells the car to use more of the rear brakes to shorten stopping distance at the expense of significant wear on the rear pads.

It's also how some torque vectoring systems without LSD work - the brakes are applied to the wheel with slippage to send power to the other wheel. This is not the case for the GS though.

Back on topic though, I had my OEM pads changed out for Akebonos well before they were "due"... the reduction in dust is very significant and braking performance is just as good if not better than OEM. I do get an occasional squeak when rolling out of my driveway on very cold winter days, but it's gone once I roll off my driveway.

im st 75000 miles and have about 50% life left 😂 although i just rotated my tires and checked the brakes, the shims look rough, i might just change out the rears soon anyways, i bought the parts when i did the fronts thinking the rears would need to be done soon
