Turning rotors?

[92redragtop]

Brembo rotors are hardened & cannot be machined
Replacing ordinary rotors gets you a part warranty, machining does not so you have to figure out the difference
With all the brine they spray on the roads, its hard to find a rotor worth machining these days.

If its a summer car that's stored & the rotor is in good shape, I could see machining a warped rotor with a ProCut as a stress relieving process that would make it a better product

It might just be that the calipers are from Brembo on the ATS (unless Brembo makes the OE pads/rotors for GM for this application) but this is a Cadillac dealer that is quoting machining as part of their brake service (pads and rotors) instead of trying to sell me new rotors. I asked them if they don't just replace the rotors with the pads and they said in most cases, no.

These are daily driver cars.

From rockauto I can buy a pair of front ford motorcraft rotors for the ford fusion for $250 cad including taxes and shipping...$160 cad for pair motorcraft for 2004 mustang. Normal delivery time to front door is 4 days.

On Rock Auto the OE rotor for the ATS with Brembos is just under $20 cheaper than buying from the Cadillac/GM dealer here (before taxes, shipping, brokerage or customs if applicable)....so pretty much same price or maybe more expensive depending on shipping/other fees.

Many times, backside of the rotor is corroded n flaking too badly to properly machine anyways.
Check Rock Auto to see what a decent new set are worth?

Dealer had the car for something else and checked the brakes (I knew I had to do them this late winter/spring) and quoted the pad/rotor service so I think they are ok to machine. I figured I had to buy both when I got to doing it versus just new pads. New front OE set at Rock is about $260/pair.

I would want to see what the GM service manual says about machining rotors with Brembo Parts
