2017 GS350 F Sport RWD. Currently at 98,000 miles. Both front and rear rotors/pads were replaced at 28,000 miles when I purchased the car CPO. I put new front pads only on at 72,000 miles, the rears haven't been touched since 28k. My question is if the rear brakes are even working? The rear pads and rotors look basically brand new, I can't even feel a lip around the rear rotor outer edge, which was noticeable on the fronts a looong time ago. So basically in 70k miles the rear brakes show virtually no wear.

I did bleed the brakes around 55k and didn't get much fluid out of the rear calipers, compared to the front. Thought maybe it was something electronic with the ABS restricting the flow with the engine off? I used a pressure bleeder on the reservoir and also assumed maybe it doesn't push out the rears as much?

I do drive a lot of highway, which is how I got so many miles from the front brakes.

Braking theory says that rear brakes do 25% of the braking. Thus, I think it is safe to presume that they should last 3 times longer
