Brake Rotor Wear And Measurement
Measuring brake rotors is critical to performing a pulsation-free brake job. It does not matter if the rotors are new or old, you always need to verify if they are within specification.
Preparing New Brake Rotors For Installation
New rotors, either OE or aftermarket, are supposed to be finished to specifications and ready to install out of the box. There should be no reason to give them a “clean up” cut. If there is one, you need to find a different rotor supplier.

Andrew Markel explains best practices for new brake rotor installation by checking flange runout with a certain amount of lug nuts attached and torqued.
Mercedes-Benz Floating Composite Rotors
When you hear the words “floating rotor,” you might think of a racecar brake rotor with Allen head bolts holding the hat to the outer ring. But, more economical and robust “semi-floating” rotors have made it onto Audi, BMW and Mercedes-Benz daily drivers.

Andrew Markel shows how anti-corrosion coating on quality brake rotors can create a win-win for your shop and the customer.
New Or Old, Rotors Must Be Measured
Installing new rotors without ever measuring and documenting the condition of the old rotor is like playing chicken with a comeback. Sooner rather than later, you will find a vehicle that will not be magically fixed by a new set of rotors. In fact, the new rotors may cause even more problems and lead to an unsatisfied customer.
