I just installed slotted rotors front and back but on the driver rear there's a circular scratch on the top portion after driving. What could it be.
First picture is the rotor I'm talking about. The 2nd picture is the rotor with no issue in the front. Also no noise is being made when driving.

 

 

I honestly dont see anything

 

Now I see it!

 

 

Does it look sort of like something mildly abrasive might have come in contact with the rotor while it was turning?

I've heard of that sort of thing happening before.

 

LOL at ssjoe...

@ cu2 thats what i was thinking, but im dont think it is the brake pad, do you think it was a one time thing that did that or is it something that is still happening as a drive...

will that scratch affect my rotor now?

 

whoa, wait.. am I going crazy?

Look at pic #1- look at where the slot ends.


Look at pic #2 and where the slot ends.


Did you buy ebay-special-straight-from-China-rotors, where the guy couldn't even create equal length slots? I'd be more concerned about the quality of what you bought, as opposed to a circular scratch on a surface that is meant to endure crazy amounts of friction...

 

I don't know man. I looked at the pictures and don't see anything abnormal. It just looks like a normal rotor.

Drive a bit more and see if it wears away.

Look fine to me, I wouldn't worry about it. YMMV though.

 

Fronts vs. Rears. Different diameters. Could be fine.

 

...ooooorrrrrrr... it could be a rolling deathtrap!

 

I think he's referring to the general circular pattern on the rotor after braking, as opposed to the thatched look of the brand new rotor... I don't know what to say

 

just plastidip it..

 

That's what I thought. And why I think it's a-okay.

 

So the guy didn't align the slots for the smaller rotors?


I doubt it's a rolling death trap, but you get what you pay for. Just speaks to the quality of the product

 

Always jumping right to the plastidip.

He should try buffing it out first.

Like with a mildly abrasive organic compound compressed into a pad like structure. Apply constant and uniform force via a circular piston.

That will likely fix it up.

If that doesn't work, then Plastidip.

 

Yeah, no clue.

zNUMBERSz: what brand are these rotors? out of curiosity.

 

That's what got him in this mess in the first place!!

 

ok thanks guys and its powerstop pads and rotors from autozone website.

 

Power Stop/Performance Brake Pads / Rotors Kit K2742- ReadReviews onPower Stop #K2742

 

Front vs rear brahhhh different sizes

 

IN the buffing process in a circular motion with some organic compound, wouldn't it be idea to put some sort of oil or lubricant ? That might prevent further scratches...

 

This is my new favorite thread.

I heard doing multiple power stops and then immediately spraying down rotors with water helps with strain hardening the material! Could prevent further scratches

 

You're not serious, are you?

 

ill have to try this... spray all four rotors?

 

 

 

make sure you are travelling at least 150mph before trying to apply the brakes though

 

Is it just on the one side?

No bolts scraping? No noise? No nothing?

 

When is Justin gunna join this thread??

JUSTIN where you at???!!

 

here, butt, I like to give good advice first before every one gives false advice...

 

lame

 

hey, i get my kicks out of helping first...then after repeated mistakes, i'll go in.

as far as the OP, I only see cross-hatch marks, no swirls or anything that looks like a foreign object or debris in the way. (except maybe Drake sitting there)

OP has nothing to worry about with his rotors.
and all he will get from splashing the rotors with water after a drive is steam. and maybe some surface rust, but by no means is a concern for safety.

 

OP still alive?

 

just that one rotor, not noise or scraping either

 

It's fine.

Do nothing.

Fer serious.

 

Sounds like it isn't a big deal then. Is it scraped on only the front of the rotor, or is it scraped on the front and back sides of that same rotor?

 

nope just rear driver rotor has the scrap

 

Have you been driving the car since you posted the pictures?

I'd be curious what it looks like now; if it's gotten better or worse.

 

ohh, i finally see the scratch in the first pic.
