2016 Acura RDX.
During a service visit late last year (at 44k miles) the front brakes were making a horrific screech despite plenty of material remaining. I found a service bulletin that was applicable to the condition (17-049) and after confirming the complaint, the dealer installed updated front brake pads and resurfaced the front rotors using an on-car brake lathe.
On-car brake lathes have always advertised being able to achieve
The RDX was just here for regular maintenance (at 52k miles) and I decided to measure the lateral runout of the recently resurfaced front rotors. Each front rotor measured less than .0005". The less runout you have, the longer your brake job will last before developing DTV. I am not sure which brand of on-car lathe was used, but my guess is that it was a Pro-cut since that is the Honda approved unit.
This has really caused me to re-think how I should do brake jobs. We have two local service providers with on-car brake lathes and they charge between $80-$100 to machine rotors on-car. From the results that I saw, I think machining rotors on-car is really a better option than just hanging new rotors on the car and sending it out.
