CPO brake question
Hi there. Question for the group. In February I bought a CPO GS350 AWD and today I brought it in for its first service. Was told rear rotors and pads needed replacement. I’ve driven it 3900 miles almost all on highway. Is this normal? I would have expected a CPO to have a little more life in the brakes than what I was told today. They said they were not an email and I could make it to my next service, but was wondering if this was typically happening to others? Thanks for any info.

You can probably go at least another 5k miles, and likely 10k miles or even more before you start hearing the metal squeal sensor contacting against the rotor.

You should have been given an inspection sheet with brake pad thickness recorded when your car was CPO'd. I suspect the brakes were barely within the CPO brake pad thickness guidelines when the car was CPO'd. I think it is somewhat common for dealerships 'to start' recommending brake jobs to their customers when the pad thickness gets right around that minimum CPO allowed thickness, which usually means you have x thousand miles remaining before they 'really' need replacing. Once you understand the madness of it all, it usually starts making a little bit of sense.

I could be remembering this incorrectly, but I think the brakes need to have 1/2 of their original thickness for CPO. But you can’t (I suppose you could, but you shouldn’t) wear your brakes to 0%. So they’ll tell you they have “half left” or whatever when they CPO it, but it’s not actually half of the useful life. Hope that makes sense. That may have been what happened to you... when they CPOed the car the brakes were barely at 50%, but that does not equal 50% usable life.
In any case, I’d say it’s likely you could drive on them for a while still, they are just letting you know you’ll need the work “soon.” I’d ask for the measurements on what’s left and do some googling.

Give us a little more info... what year GS and how many total miles? Brakes are always a conversation topic on this car, but many members get pretty long life from their pads and rotors. Did the tech actually provide you with the actual measurements of the rotors and pads? They should be on the invoice.

Are you sure this was a CPO car? I thought the Lexus CPO guidelines were cars under 60k miles and no accidents etc. Not really doubting you, but a CPO 79k car doesn't sound like Lexus.

Went through this myself...CPO brake pads and rotors should be about at 50% life or 5mm-6mm thick. Its likely that your car met the minimum CPO spec for pads and rotors just like mine did: https://www.clublexus.com/forums/gs-...-4k-miles.html
At 79k miles, its not surprising that its time for the brake/rotor change. If you have the carfax, it should show when the last time brakes/rotors were done if it was completed by the dealership.

It used to be a maximum of 6 years or 70,000 miles, but Lexus changed it to 6 years or 80,000 miles now.
Thought it was a pretty good deal anyway.

CPO guidelines state that the brake pads must be at 6mm or thicker to pass and tires must be at 5/32nds or more to pass. Most dealerships will recommend replacement of pads at 3mm. If the rotors can't be resurfaced (pretty common) due to being resurfaced before or "lipped" on the edges, then "in theory" you can go further than 3mm considering you'll be replacing the rotors and pads at the same time. There was also a bulletin that came out Jan of this year referring some GS models to an updated updated shim kit that is suppose to reduce the squealing noise most of us deal with. The shim kit has some type of material on it rather than just a metal surface. I'll be trying that on my next round of brakes...
