Does anyone or can anyone, have/take a pic of the front SC400 brake rotor/calipers for me.

I had a shop install a set of 400 fronts and for some reason, I think they forgot something...does anyone know what holds the rotors to the hub? I thought that there was a screw but I don't have one...if anyone could help, I'd appreciate it!
Thanks, Tanner

 

I'm almost totally certain that the rotors are "free floating". Meaning that they are held on by the wheel itself.

The screw should be from the factory and was used during assembly. At least that is what I always understood.

 

Yes, rotors are free floating. Wheels hold it against the hub.

 

yeah the wheel holds the rotor on.the screws are there from the factory to hold the rotor on during manufacturing, if im not mistaken

 

Free floating rotors.

The 2 empty threaded holes you see are for 8mm bolts to thread into so you can press old rusted rotors off of the hub.

 

Thanks you guys are money!!!

one more question... since they are free floating rotors, when the wheels are off, is it natural to have some play on the rotors? only thing holding them from falling off is the calipers?

Thanks, Tanner

 

Yes, there will be some play as w/ the wheels off, the only thing preventing the rotor from being removed is the caliper surrounding a portion of the rotor.

 

Thanks! You guys are the best!

I don't mean to hijack this thread, but as you can see from my other posts, I am a mechanical zero. I'm due for a new set of rotors, front and back. My pads are fine. Is that something I can do, or should I let the mechanic do it? I don't have any tools other than the usual stuff mechanical zeros have.

TIA.

our rotors are not free floating. they are held on by rust.

 

It really depends on what you have in terms of tools.
You will need a set of sockets.
A set of wrenches may help as well (as they provide a bit more torque than using sockets and you can bang on them if you need to apply a bit more force).

You will have to remove the nuts/bolts that mount the caliper to the hub area. For me, this was the most difficult part, as mine were rusted in. I don't remember the size, but it is somewhere between a 12 - 19mm metric. (This is where the wrenches come in). I had to bang on them to get enough torque to break the bolt free. (If I remember correctly as well, I think one of the bolts, would not budge. I had to bust out an impact wrench w/ a universal joint to pop it free. Just one of them random PITA issues that you may come across).

If you can do the pads, you can easily do the rotors too.

 

rotors just fall off, or are pounded off after the rust is out of the way, and the calipers are removed... how good are your pads?

keep in mind if you only replace the rotors, you will want to lightly sand the pads to eliminate any grooving the old rotors may have left to keep from damaging the new rotors...

 

I say, take it to a shop, brakes are pretty important. You really don't want to mess that up. just my 2 cents.

 

Thanks for the input. I think I'll go with SCon20s advice and take them to the shop...

 

Dude you can do this. I will take you no more then 30-50 min tops.
