Chipped brake drum Would you use it?

[berniedd]

Chip is on the outside of the outer lip, not the metal lip that contacts the brake shoes. I would use it with no worries.

There is a little overspray of blue paint past the chip. OP was directing his sprayer from the outside of the drum, the spray got past the chip area, and deposited as a crescent shadow of the missing metal on the inside of the drum's inner lip. I believe the chip was there even before he started painting.

What a trip that a lot of the posts to this thread are some kind of "theory" as to when the drum was chipped. The OP was simply asking if he should use it or not. And here we are, three pages of posts in, expostulating over something that has nothing to do with Mazdamonky's question.

I'm guilty of starting it by agreeing to what I believe, is your honest assessment of damage. It began a spiral effect of scrutiny and analysis that is completely off topic to the subject matter of the thread title.

Nissan Micra baby !!!

A Micra is considered a high performance vehicle? Must be a Canadian thing.

No lol. they do have a race series here called the micra cup where these cars are raced looks to be a lot of fun.

No do not use it. It has been dropped. It is out of balance and might have possible hidden cracks.
Brakes = yours or someone else's life.

Take a look at my harmonic balancer thread. At first after I damaged the potmetal pulley, I didn’t even see the damage. It was still hanging on even after I messed with it. Only when I really messed with it, did I break the piece off in earnest.

it can happen, it might have been a very minor crack until OP was examining the paint job, saw, messed and broke it off. I’m willing to give the benefit of the doubt based upon how my pulley broke off. The truth is between OP and their creator, not us.

You are 100% correct.

I simply asked a question as I'm used to during an analysis and looking back can see where it could have been legitimately interpreted as a veiled accusation ( which it was not).

I also amended my statement in #36 to the conclusion you brought forth when I got back to my personal computer with better ability and did in fact see tell tale signs of a pre-existing fracture.

I’m on a iPhone but I zoomed in and I see what you mean.

Yeah, one thing in Forensic Engineering is to question everything, test everything, assume nothing and verify. ( repeat as required)

Contact Rock Auto, if they want a picture clean it off with carb cleaner.

I'd be concerned about a crack forming under heat cycling. It may look fine now, but there could be a microscopic crack hiding somewhere around that area. Return it.

 

[Jetronic]

to get another with hidden cracks?

I'd check it for cracks and drum dimensional distortion. If none are found, grind the roughness smooth, and grind a similar cutout 180 degrees away from the original. If those conditions are met, it will hold up just fine.
