How many miles should I expect out of rotors?

My rotors are down to 20% after 50k miles. Is this within the expected range of miles?

I brake later- harder than most. 50-50 highway-city driving. 10% dirt roads 90% pavement. Im in the Boston area, bu I don't tailgate!
Thanks

Rotor and pad life depend on how much you actually use the brakes, not so much the mileage so it's kind of hard to designate it like that. They're wear items, so you simply just go by their condition. How are you certain the rotors are down to 20%?

Personally, I just make sure my rotors are not warped and see if they can be resurfaced; then just slap some new pads on when the time comes. If they're bad, then I would get a new set of rotors along with pads.

That sounds right on target for wear, with your driving description.
Check thickness versus minimum on the rotors. If they can be turned, do it. If not pick up some new centric rotors and expect the same life out of them.

50K out of a set of pads/rotors is pretty good no matter the vehicle these days. Personally I don't see any value in turning rotors anymore. Between the time it takes to remove them, take them to the machine shop, wait, pick them up, and then slap them back, then hope that big Bob did a proper job resurfacing them. How much is your time worth? How much are you actually going to save dollar wise? Just replace all rotors and pads, do a proper bed-in procedure and call it a day. You'll be worry free for another 50K plus. Just one man's .02

^^ this guy does have a point

I may be lucky to have a store 10 minutes from the house that does rotors for $15 each while I wait (or get lunch). My last trip there was with the Brembo rotors ($$$) so I saved a good chunk of change.

But it is all relative depending on cost vs. time vs. convenience

My 2010 Forester still had the factory rotors after 8 years, 197k miles and two brake pad changes. Never had a rotor problem but I'm pretty easy on brakes and often used the sport shift for engine braking while driving downhill in the mountains.

Your rotor and pad life both depend on your habits & usage, speeds, roadways, traffic, loads you carry. 50K miles on rotors is pitiful based on my experience, I got longer than that even on any of my 14 assigned police cars in a 31 year career, but I knew guys who were plain "hell on brakes".

Those are police car spec brakes. We don't have that option unless we upgrade to something like Brembos. My wife has destroyed OEM 98 Forester brakes in less than 20k of downtown Atlanta driving several times.

Exactly. If there were a lot of stop and go like in any downtown area, the life will decrease dramatically because of high usage.

The higher, the fewer.

Police car brakes used same rotors, pads were more aggressive however, and often in a day's work, involved a few stops from over 100 mph.

I learned to anticipate needs to"stay off them brakes". Let air resistance, space, time slow you too.

Besides, no police car brakes on any of my POVs, and except for a '73 Mustang, I never needed to replace POV rotors. That Mustang was a car I had in the '70s, turned rotors twice at least, but they would warp again. Finally bought new at NAPA, then in time, sold car.

I even usually don't use OD unless down grades or flatter highways. Take Rt 8 from Christiansburg to Floyd, no need or use of OD at all.

I got 37k out my brakes. Mostly suburban driving. Front brakes could have gone a bit longer. The rears needed to be done immediately. At least brake work on these cars is pretty easy.

On my MY01, I got nearly 150,000 miles on the rear rotors, and maybe 125,000 out of the front rotors, probably would have gotten more if I did not have other front end issues.

Here in NY, rotors usually rust up after 3 or 4 years. I don't think I've ever worn a rotor thin, just they get rusty and start eating pads or causing the car to shake

After 30k miles on our 2018 Touring Edition, my rotors look absolutely fine, front and back. And the front pads are at half-life, according to the Subaru dealership. However, they tell me our rears pads are toast, and have to be replaced in the next few months.

They also want to replace the rotors while doing so, which seems unnecessary. Asking $426 for rear rotors and pads and labor. That's nuts.

I had the rear pads and rotors done at 37K at about that price.

I use the brakes harder and more frequently driving in the metro Boston area. Going from 75 to 30 on 128 has to be tough on them. 😉
