I have a 2001 RX 300 that I bought used from a car dealership...it was a single owner trade in.....I bought with about 60K miles....It now has 82K miles

The brake pads were replaced and the rotors were turned at 60K by the dealer....I do not know the brand of pads they used..

I can see the front pads through the wheel and they appear to have a fair amount of pad left....

I can not see the rears very well but they looked fairly thin.....

With only 22K miles on them would you expect the rears to be worn already???

Thanks in advance

jcjr- Almost everything about vehicles today are different than they used to be. You used to be able to figure 1 rear change to 2 front changes. Now there are vehicles that the rears don't even last as long as the fronts. The rears are also significantly smaller than the front's. They have always been smaller, but not generally as much smaller as they are now. I wouldn't worry too much about it, just the nature of the beast today on SOME cars. Just keep a closer eye on them since you know they wear faster, you don't want to turn those rotors again. Toyota puts very high quality parts in their cars and the rotors are no exception. I don't think you should ever have to replace rotors (especially on a Lexus) as long as you don't ever let metal rub metal. A few small lines and imperfections are normal from wear and have no detrimental affect at all on the braking, the pads quickly adapt to those lines. All you do when you let them turn your rotors (unless they are grooved pretty bad) is make them pretty for a little while and assure that you will have to replace them sooner. By the way, the rear pads are not near as thick to start with, so expect to replace them possibly before you have to replace the fronts.

I had a same question. About 90k miles, my rear rotors and brake pads looked thin. I went ahead and buy the rotors and pads from the dealer. Then I found out the brand new rear rotors were also very thin so I figure I didn't really need to change the rear rotors. But I did change the rear brake pads on 100k miles and the front brake pads on 150k miles. Both front and rear rotors may last forever...in my case!
