I have recently priced used brake lathes(I tend to do that once a year) and at today's rotor costs for most domestic and Asian vehicles it just didn't make sense.
Leading evidence: 'Use brake lathes(i tend' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace brake pads' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion · Original poster
When doing a routine brake pad change do the rotors need to be turned?

Suggestion
Unless your rotors are worn to the point you need to replace them, just replace the pads and bed them in.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Salsilverbullet is correct and saved me $$$$ with that advice and it worked for me.
You will be hard pressed to find someone that turns rotors, especially someone that's willing to turn a drilled rotor.
Measure thickness. If you have brake "judder" then replacement might be your only option.
--Aaron
I have machined them before but only on "like new" rotors that only needed a very fine cut........the wear limit is 1mm per side so it doesn't take much wear to be beyond the wear limit so turning them is almost never possible and stay within the wear limit spec..

The space the brake lathe takes up is another concern.
I can either have a tire machine or a brake lathe, not both.
I typically replace rotors when replacing brake pads.
I might skip replacement on a Porsche once, if the rotor is still within spec.
The tire machine keeps getting put off, but I might have one before too long.
I get many requests for tire mounting and balancing.
A lot more than I get rotor/drum turning.
Unless your rotors are worn to the point you need to replace them, just replace the pads and bed them in. The oem brake system is incrediably tough and durable made by Brembo. Your oem rotors will last longer than your oem pads. If you haven't replaced your brake fluid in a long time it would make sense to do it.
