Is this worth worrying about?

[JonesnSince78]

Maybe I'm being too obsessive...

I'm hoping to do brakes this weekend (rotors, pads and rebuilt calipers). The nearest P-car dealer is a hike, so I ordered rotors and pads from one of the dealers who sells online. The parts arrived today and I was less than thrilled with the packing. All four rotors (inside their factory boxes) were put into one large box with lots of dead air space and a little bubble wrap. Needless to say, the bubble wrap did little to prevent 80 pounds of rotors from moving around. The outer box looked trashed on arrival. I inspected the rotors and three show no signs of damage and using a straight edge, don't look bent. The fourth isn't bent, but has a chip on one edge, pictured below. It's about 5/8" long, but only about 1/16" deep. I think it's out of the way of the pad so it won't interfere with it. But, I'm wondering if this would throw off balance at all? Are rotors even balanced at the factory? Would you use this?

From what i understand from the rotor making process is that they are cast, then drilled, slotted then coated, plated, whatever...Then after all that is complete they put them on a machine to balance them. Alot like your tires, except material is taken off instead of weights added.

Anyway they grind off till they are acceptable.

You should be able to go to a NAPA auto parts or a machine shop and get them balanced if it worries you. They should have already been done but unless you see some work done it needs to be.

Thanks. The chipped piece shown in my pics is definitely from shipping damage. So, it's after the balancing at the factory. I'm just not sure if it's enough to warrant messing with. Oh well, I guess there's only one way to know for sure. What a pain, I wanted to do this job tomorrow...

Definitely say something... anything with the brakes is worth fussing about.

Hopefully they would rush you out the one rotor, then you can send the damaged one back.

Send it back for exchange and let them know about the packaging. Same thing happened to me and they exchanged the damaged rotor and paid for s/h too. The damaged area will probably cause a hot spot and vibration issues and what ever you do, don't take it to NAPA to have it turned.

Hi,

I would grind them smooth and use them. The little bit

of metal that is gone will not cause a significant amount

of in-balance in my view. I would never buy my next brakes

from this place again.

I buy my brakes from EBS racing in Nevada and their staff

have been great. I like the Pagrid blues.

Good luck.
