Grooved Rotors Make me sad face :(

[AmBo]

Check it out. Think the caliper or the pad is to blame? What should I do about it? I was planning on getting new rotors in the spring but F that if they are just going to get tore up by the caliper.


Sorry about the quality. Was taken with my camera phone @ only 2MP.

Was there something stuck between the caliper and the rotor? Looks it...the rotor shouldn't wear like that.

Ouch that sucks. I agree with sanman that something might be between the pad and the rotor. You could take the caliper off and look at the pad surface. You could also maybe get the rotor resurfaced.

 

[AmBo]

Nothing was stuck there to my knowledge. I haven't taken the caliper off yet. Is this dangerous to drive on?

 

[NismoSER]

Dangerous? No, its not dangerous. But the only "remedy" is to resurface the front rotors (looks like your Cobra calipers that I put on, so I assume front) and replace the pads with new.

If its time for new pads, then obviously that's a good time to resurface the rotors. Otherwise, you'd probably be ok riding it out until new pads are needed.

Paint the center of the rotors silver if you take them off.

 

[AmBo]

I'll be getting completely new rotors in the spring so no need to resurface or paint. I need one's where the center is painted as rust is ugly.

As for the pads, I may as well just slap new pads on at the same time. Thanks for the replys guys

I got 2 cobra slotted drilled zinc plated rotors for $100 shipped. Rotorpros.com

How's the quality of the rotor?

 

[san~man]

I got the Brembo's from Tirerack. They were pricey, but worth it IMO.

Just beware of the "Brembo's" off eBay. The majority of them are slotted/drilled/or both by an aftermarket company using a plain blank. I can't say for sure that the AM company's techniques are better or worse than Brembo's, but I went with the "genuine" drilled rotor just for peace of minds sake.

Wont be using them till my car goes back on the road in the spring. They look sweet tho.

Take the caliper out and have a look. A peice of road debris or something could have lodged into the caliper and caused that groove. If you remove it, you could just put the caliper back on and continue driving and the groove will slowly disappear over time as the rotor and pads wear (or until you replace them)

seconded.

i had a set of the ebay cross drilled and slotted on my 94 tbird. While browsing another site, i viewed where a guy had a set of the same ones on his eclipse, and while doing 75 one cracked and took out his whole drivers side suspension and rim went bye bye and he flipped the car a good 3 or 4 times into a cornfield. i drove right down to autozone and picked up a set of normal rotors, and installed them. low and behold, the cross drilled/slotted ones i had were showing signs of cracking.

i think it has to do with the fact the brembo/real ones are forged with the holes and/or slots in them, and the aftermarkets are just drilled and slotted afterwards, which lowers the integrity of the rotor.

Thats not bad and its nothing to worry about. I had a groove much much deeper in mine before I went to 13" equipment. Its usually caused by a tiny rock or something getting stuck between the pad and rotor.

Its not dangerous at all, and technically grooves in the rotors will help you. Concentric grooves add extra surface area for the pad to sit in and contact for braking but it can sometimes put strange feedback through the pedal.

Anyway, as far as repair, get new pads and have the rotor turned at the same time if you're that worried about it. If the groove is not getting any worse then whatever debris it was is gone, if it does continue to grow you can take the pad out and scuff off any debris.
