Is anything securing the brake rotor to the hub, OR it just sit on the hub and only get clamped in place once the wheel and lug nuts are installed?

Just like the tittle says, Is anything actually securing the brake rotor to the hub? OR it just sit on the hub and only get clamped in place once the wheel and lug nuts are installed? This is for the Brembo 6 piston Brakes.

Thanks guys, trying to see if I am missing something before putting the wheel back on...

Did your rotor fall off?


Some cars use a single set screw to hold the rotor in place. After that the wheel and lug nuts fully secure the rotor to the hub.

With the brake pads and brake caliper in place, the rotor isn't coming off willingly.

No it didn’t fall off. Just wanted to confirm that there’s anything holding it other than the caliper and then the wheel and nuts.

the only reason IMHO for that little screw that holds the rotor to the hub face is to keep the rotor on the car during some part of the assembly line process.

Some manufacturers use a spring clip over a lug stud to do the same thing

First brake job those retainers get snipped with side cutters and off it goes to the trash

If you don't put it back nothing is going to happen, the rotor is clamped in place by the back face of the wheel and front face of the hub by the lug nuts and studs

It is more important that the front face of the hub be clean of rust/corrosion and the same for the rear of the rotor so that they are parallel to each other otherwise any crap will cause a runout condition and more than a couple of thousands of an inch of that will cause you a pulsation in the brakes

A light coating of anti seize on the face of the hub and around the register ring is your friend BUT DO NOT PUT IT ON THE LUG STUDS THEY MUST BE DRY TO TORQUE PROPERLY

Yes... it's bolted to the upright, that's bolted to the suspension links.

The rotor is not bolted to the upright.

Something ain't right if it is.

Another example of why you should never trust answers from the internet.

It's perfectly fine to trust answers from the internet.

Just be sure to verify them.

For some reason I thought I saw a picture with this thread, which showed a caliper adapter bracket....that's why I replied like I did.

wrong thread I think
