Should rotors turn freely?
Turning a rotor allows for smooth braking action and creates less heat then those that are warped. Typically you want to have your rotors turned every other brake change. This will ensure the maximum amount of life to the brake pads. Realistically rotors can only be turned so much before they need to be replaced.
Do brake rotors spin with the wheel?
What Are Rotors? The rotors are the circular discs that are connected to each wheel (two in the front and two in the back). This friction resists the spin of the wheel, which slows it’s rotation and movement of the car.
Is changing rotors easy?
Modern brake systems are complex, and while replacing your brake pads and rotors is a fairly straightforward process, it could go wrong if you aren’t sure what you’re doing.
Are brake rotors supposed to spin?

What causes brakes to shimmy right after rotor and pad?
The shimmy feeling that comes from brakes is usually due to uneven friction material build-up on the rotor. This transfer from pad to rotor is supposed to happen, indeed it makes the brakes work better, which is why brakes function better after break-in.
What to do if your brakes pulsate after rotor and pad?
Check all installs with a dial indicator for runout. Spin the rotor with indicator at 90 degrees on the rotor face near the outer edge. Runout should be zero, must be under .004″, the less the better. Clean pad back, piston, and caliper. Replace shims. Proper and complete lubrication of all metal-to-metal contact points.
What should eccentricity be on rotor and pad?
Thickness eccentricity should be zero, must be under .0015″. Check all installs with a dial indicator for runout. Spin the rotor with indicator at 90 degrees on the rotor face near the outer edge. Runout should be zero, must be under .004″, the less the better. Clean pad back, piston, and caliper. Replace shims.
