It is up to you but you might consider replacing the pads and the rotors and all other hardware that is supposed to be replaced at the same time.
Leading evidence: 'Replace pads and the rotors and all other hardware' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace pads and the rotors and all other hardware' (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.

please advise of the thickness allowed before replacing rotors.
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.

please advise of the thickness allowed before replacing rotors. i need to replace pads not sure on rotors. 56k miles on car and no tracking. Assume would need to have turned to reuse current rotors....help appreciated. Thanks
Chances are the rotors while not yet at the minimum thickness will be there way before the new pads are worn enough to trip the brake warning light.
It is up to you but you might consider replacing the pads and the rotors and all other hardware that is supposed to be replaced at the same time.
Or you can measure the rotor thicknesses then install new pads (and again renew whatever other hardware is called for) and then monitor rotor wear and when rotor wear has the rotors down to their minimum thickness replace the rotors leaving the replacement pads in service provided of course they are still in good shape and have suitable remaining thickness.
But the above is a lot of work for the average owner. Thus replacing all the brake hardware, pads, rotors and other hardware (and this is a good time for a brake fluid flush/bleed as well) takes the worry about the brakes away for another 50K or more miles.

Why shouldn't cross drilled rotors be turned? As long as they clean up and are not below minimum thickness after the process I'm at a loss to understand why they shouldn't be turned (or resurfaced via a grinding process)?
Sincerely,
Macster.
The Average shop will not take the time to re-chamfer the holes holes and doesn't have the experience too properly turn a rotor with so many interruptions in their cutting process. You end up with 2 issues afterwards: Sharp Edges on the holes (without breaking that sharp edge you are creating a Heat riser that will increase the Thermal shock to the holes... thus, speeding the cracking process) as well as poor surface quality from the interrupted cut. Now if you can dual grind both surfaces at the same time and then little break the sharp edge on the holes.... Go ahead and resurface them. Any shop that is capable to do all this work will charge you more then the rotors are worth. Final note: Very few automotive shops will take on the Liability of turning Drilled or Slotted Rotors!
Thanks.
I was not aware the hole chamfers would be lost. I assumed the chamfers were deep enough to provide some chamfer even if the rotors were worn to their minimum thickness.
Now I have to go out and look at my Turbo's brake rotors.

Macster.
