Anyone seen rotors like this?

Anyone know what can make a rotor look like a record player?

Attachment 131769

I have an hour drive home so you can understand my concern when I started to hear a roar then a vibration in the steering wheel. It got so bad that I could swear that a tire had blown and was coming off the rim. I pulled over to a safe spot but couldn't find anything wrong. Full pressure in the tires and they appeared fine. So I limped it home and immediately put the front end in the air. I checked all the linkage, bushings, and drive shafts and everything is tight. Then I noticed the rotor on the drivers side. It has deep grooves and what looks like hot spots of discoloration. The pads and calipers came off effortlessly so I don't think anything was binding up. These are stock rotors with stoptech pads. I'm not sure where to go from here. Has anyone else had similar issues? :confused:

What do the pads look like?

that be either no pads and or locked piston

Looks like really bad glazing to me. I'd find a shop to do a very light resurface if the thickness is good (otherwise replace them) and bed your pads in again (if there is still life on them).

Yeah, I'd also say a sicky caliper piston. Check the pads too.

I would not reuse the pads. With grooving like that, the pads are very likely grooved themselves already and will transfer those grooves back onto a new/resurfaced rotor.

I would just get a new set of rotors and pads and check the caliper pistons prior to going out to rebed everything.

You need a caliper and/or the slides on the adapter bracket are frozen.

I figured I would replace both pads and rotors. I don't want to take a chance that I would ruin the rotors with the old pads and this gives me an excuse to tell my wife I need to upgrade the rotors with slotted. The strange thing is that when I pulled the calipers apart they came off so easily. Could a clog in the brake line or a malfunction in the traction controls do this?

maybe your wheel bearing took a shit.

I had similar lookinv rotor when one of my pistons seized, except when I pulled over to check the rotor as glowing red! Perfect opportunity to upgrade to a "safer bbk" that's how you sell it to widely!

I thought of that. I know it's not always easy to tell, but there isn't any play at all. Ill get a chance this weekend to get further into it.
