Capliper Grinding against the rim

[SHOguy 92]

Posting from college between classes real quick.

On my way to school I come off the freeway go to slow down and all of a sudden sounds like a bad wheel bearing and it gets louder the slower I go. I pull over hop out take a quick look and everythign looks fine the wheel isn't crooked at all. Only 1 mile till school. So I hop in the car take off same grinding, take a corner and pick up speed to 30mph sound almost goes away. Pull into the lot and slow down gets loud again. I had no time went to class.

Well I just went and looked between classes. My caliper is litereally sitting on my rim! I got to head back to class only thing I can figure that would cause this is broken studs I pulled off the cover and all them were still there.

Sounds like a bad wheel bearing (possibly a backed out axle nut).

Or a caliper bolt came out.

I think that rotor would have to go with it for it to contact the rim spokes... which BTW, where on the rim is it hitting?? That is valuable information.

that exact thing happened to me right down the street from my house. the caliper bolt broke or came loose, cause it wasnt there anymore. the front half of the caliper popped up and was only halfway engaging on the rotor. where the caliper was sitting up high it was grinding against the inside of my rim. mine was grinding so hard and got so hot it was producing smoke and burnt the rubber sleaves on the bolts. i come to find out that the caliper on the car was not the correct one after buyin a new one. so my rim lost a lil weight

I found out a while ago that if you don't tighten them caliper bracket bolts real good then they'll back out on you, and the exact same thing you're describing happens.

None of his SHO's have caliper brackets.

If it were rubbing on the spokes I'd imagine it would make more than a grinding noise.
