New brake standards

Notice all the nice mandantory proceedures to achieve 0.001" maximum runout vs the old spec of 0.0028". ITB04-026a 8/16/04

Doubt any of this is done at any aftermarket shop, probably not at dealers either as the allowable times are too constraining

what's a ProCut PFM, and what does it do?

On car lathe to mis cut the rotor to match [cancel out] the bent [out of perfectly true/bearings hub.......rust films can be greater than 0.001" which gets multiplied by distnce from hub to rotor edge.

A precison [perfect] rotor runout correction can add an hour each to a brake job.

Wonder if Infiniti noticed that the 300C SRT8 has the 14" 4 piston Brembos in front and the 12" 4 piston Brembos in back?

Time for Infiniti to quit using old pie pans for rotors on their heavier vehicles.
