Honda CRV minimum rotor mm

I'm considering purchase of a 2020 Honda CRV with 19,500 miles. According to the dealer certification, the brake rotors are at 27mm in the front and 9mm in the rear. I'd appreciate some information on original equipment minimums and estimated remaining miles. Of course I don't think brakes are needed now. As I don't have the car, I can't examine them myself.
Thanks.

 

I've never heard dimensions like that given for rotors. Could those be the brake pad thicknesses?

 

I think you are referring to the thickness of the brake rotor.
The rear rotor surfaces are solid, and new are about 11mm thick. Discard thickness varies by brand, but usually around 8.5mm.
Front rotors are vented, and new are about 26mm or so thick. Discard is around 23mm.

 

Minimum Thickness will be engraved on the brake rotor's hat (flat section near hub). It should state either 26mm or 23mm, with the latter being .905").

New Front rotors are 28.0mm thick w/ 26.0mm or 23.00mm minimum limit
New Rear rotors: 11.0mm thick w/ 9.0mm minimum limit

If your Honda dealer has certified the front brake rotors to be 27mm the front rotors have only worn 1mm. Since front brake pads and rotors wear much quicker than the rear I presume you may have already had the front brakes replaced once before. I'd guess you should still likely have 5k-10k miles before the front rotors wear another 1or 2mm down to the 26mm or 23mm limit and need replacing.

On the other hand however, the 9mm on the rear rotors is indicating the rear rotors need replacing now. I presume the rear brakes have never been replaced, but the fronts have. Otherwise, the rear brakes are wearing unusually faster than is typical.

 

< 20K miles would be awfully early for needing brakes unless the previous owner was a speed freak who did a lot of fast driving and hard braking.

 

Thanks for your help. I was able to see the caps. They show 23mm and 8mm, respectively.

 

I agree. Either the previous owner was heavy on those brakes or he was pulling something (a trailer etc) that was too heavy for that vehicle and had to apply hard braking to stop the vehicle. Of course we'll never know what the reason was but, something was hard on the brakes. Look for evidence of a trailer hitch or trailer ball that may have been removed etc. Just thoughts. Again we'll never know probably.
Either way, if the owner didn't take any better care of the car than either scenario, I'd be leary of what else he abused.

Maybe there's a mechanical issue with the car that has cause excessive wear on the brakes.
