^ I would want measurements. Most brake pads are recommended to be replaced at 4mm or less. Rotors really should be replaced with pads, most can't be resurfaced.

Rotors will last for several pad changes even if one tracks the car without any maintenance required to them. Two separate parts. Two different life spans. Cheers! |

At what point in the rotor life though does its heat dissipation start to diminish? That would be the one reason I would consider pads and rotors at the same time still. The last thing I want is to just get new pads, then a few thousand miles later start having warping issues due to decreased heat dissipation.

I change my rotors based on heat checks, as i track my car and want to avoid a rotor possibly splitting. My primary DD is a Tahoe, which weighs almost twice as much, has smaller rotors and goes 20+k miles per year. I suspect its rotors would last a good 5 yrs if not longer (but i trade them at about 3 or 4 yrs). So, a lighter car, with bigger rotors, as a DD should last at least the same if not longer. Officially, a rotor has a minimum thickness after which it should be replaced. Ut keep in mind this is for a sports car expected to run on a race track at high speeds and hard braking 10 times per 1.5 min or so, over and over. But i suspect 99% of folks out there have no idea about it and just keep driving their vehicles. I have never heard of a rotor not being able to slow down a vehicle due to its lack of heat dissipation under normal DD driving. I suspect there are plenty of 10 yr old vehicles that have never seen new brakes, or fluid. Probably just a set of pads. Bottom line and since this is a PERSONAL SAFETY issue, id say go by the min thickness spec and discard my musings. Cheers! |

This is BS, the 6 piston brakes are good.

It's faster.

I'm pretty sure he meant the dealer wants to change the brake pads and rotors, not retro fit another entire brake system onto the car.

Ah, well since they said brakes, I was just assuming they meant brakes.
