How long do brake rotors last?

I got 20k out of my first LR OE rotors. At that time I was frustrated with the short length of life, as they said they could not be turned either. I picked up a set of 4 EBC drilled and slotted rotors. When I replaced them, because I was redoing my suspension the EBC still had some life, but had put 83k on them.

My driving style is mild, and I generally try to stay off the brakes, but I live in a city. So for comparison purposes, I got considerable more life out of the EBC. In addition, you should give them a very light turn at each new pad fitting to keep braking smooth and easy.

I hope this helps.

Not always possible to take a light cut off cast iron rotors. Cast Iron subjected to repeated heating/cooling cycles forms a hard skin. The machinist needs to take a sufficiently deep cut to get under the work hardened skin to be cutting in the soft metal underneath.

I reckon thats huge km's. I'm a modest driver but the brake pad warning light came on at 45K. Warning here is to get the car in for pads straight away as my laziness in doing a few more K on them cost a set of front rotors as well

Sold Discovery 1 after 14 years, 260,000km on clock, mostly city freeway, and original rotors still OK. (Just.) Never skimmed as always smooth when braking. Changed pads at about 80,000 km on average. Occasionally towed Larson 24 foot bowrider, ~2000kg, electric brakes.. Now somewhat alarmed at rate of brake pad/rotor wear reported on this thread on disco 4.
At first service, 26,000 km mechanics report brakes 20% worn so maybe I'll get reasonable kms especially as now in wine country and off roading sand only..Also got lighter boat.
Discovery 4 HSE, 2011.

At a recent 60,000km service pads were reported as being 25% worn rear and 35% front. I have a mix of rural/city driving, time in the VHC using high descent and but am generally a light user.

I can report that the brakes and abs is awesome - I had an experience where an emergency brake pedal pressure was necessary triggering abs - makes a bloke think something breaking but it was just the system doing its thang
