76k miles on thr rear pads on a 98 GS 400 and they are now just needing replacement. Usually I do rotors every other brake pad change. They look and feel fine, but the mileage is what concerns me, though in reality the wear on the rears at 76k is the same as the fronts at 35k. At any rate, I want to see what the experience has been here? Hate to put new pads on and have the rotors warp on me...

Thanks

The determining factor is the thickness of the rotor...if its below spec then you should replace. One of the causes of warped rotors is the use of impact wrenches to install wheels. Always use a torque wrench to set the lugs to spec.

What sock said......just take them off and have a local auto parts store turn them for you for $8 each.

i dont think they even recommend you turning the rear rotors,,,,,, if you didnt drive on them metal to metal,,,,, u should be ok by just dropping the pads in,,,,,,,, but i may be wrong

I thought this was the current thinking as well. But even though they arent "scored" they still don't feel perfectly smooth...?

That's what I do, I don't think turning does anything except lower the life you the rotors ('cause metal is removed). I don't think miles matter, just how much braking has been done. Takes me about two sets of pads to wear rotors out, no matter if it's the front brakes on wife's minivan or rear brakes on my Vette.

I have a 99 Rx 300 with 65,000 actual. Just replaced the pads front and rear and they are working perfectly and used original rotors (perfect condition). Unless they are warped or grooved from rocks, etc., or your particular model has had trouble with the rotors (check with lexus dealer for bulletins) you are throwing your money away. Toyota makes very, very, durable rotors (we've ownrf several of their vehicles, our other car is a camry. Hope that helps.

To be on the safe side you could have the thickness tested with a micrometer at a local Pep
Boys but they always want you to throw them away the first time. I think Vette Boy has a good standard: Two sets of pads per rotors.

Unless you're a very aggressive driver and enjoy the smell of super-heated brake pads, relpacing the pads is all you'll need to do.

Check the width just to be sure, but I'll wager they've another 75k in them (for normal driving).

I'm about at 75k on my rear rotors (the whole car in fact). They'll go at least another 50k, and I consider myself a spirited driver.

I'm thinking of replacing my pads only as the rotors look in pretty good condition, but the local store is out of rear pads and it might take a while to get them. Is it a good idea just to replace the front pads? I heard most of the usage comes from the front anyway. I'm thinking of doing it either today or tomorrow...

i replace the pads when I start hearing the wear indicators and a visual inspection shows the pads are pretty worn...if the rear pads are still pretty thick...no reason to replace.
