What is this mystery part? Fell out while doing a brake job.

[Gasbuggy]

I did rear brake hoses/calipers/pads/rotors on my mom's 07 CRV last night. Rushed it because she needed the car back.

I always do brake work with a cardboard box with newspaper/junk mail underneath to catch all the junk that falls off.

I was putting the old calipers in the boxes for cores and found this clip in there.

I was working with earbuds in listening to music so I never heard whatever this is fall out.

Does anyone have a guess what it might be?

Hopefully I don't have to go get the car and take it back apart. Hoping it's some piece of road debris.

Rotor retains clip. Goes on the stud.

Yep.
No worries, not needed.

Agree that is what it looks like.

Don't see anything in the parts diagram that looks like it.

I thought Honda used 2 small screws per rotor to keep them in position.

At least that is how my 06 odyssey and 07 accord are with the 2 screws. I don’t recognize the piece.

When I saw the picture, before reading your post, I knew it was a Honda. I believe it goes between the caliper and caliper bracket.

 

[DuckRyder]

Not seeing it.

the one thing that bothers me (well 2 really) is that it looks too deliberately formed around the inner circumference. The other is that it was still there on that old of car.

Many makes use some sort of push nut on one of the studs to hold drums or rotors in place during assembly and that's what it looks like.

Hall may well be right though, but i don't see it in the diagrams.

I got it mixed up - goes between the bracket and the knuckle. Item # 26

AH knuckle to caliper bracket.

Yup id put that back in for sure.

 

[Gasbuggy]

Thank you very very much everyone, I was worried it was something from the emergency brake assembly.

I'd probably order four then see what is/is not there with parts in hand. Looks like they were ~$1 ea, but not sure if that was before Irrational Global Panic.

Did you remove the caliper/brake pad bracket?

Some models have two shims to properly line the bracket up with the rotor, my eye sight isn't the best these days but really it reminds me of this but if the bracket wasn't removed than it's not a possibility.

 

[Gasbuggy]

Yes. Wasn't aware they used spacers, have not seen one fall out before. I've probably had these brackets off 3 other times over the years. I always clean out the slide pin grease with q tips and brakekleen when I do pads or pads/rotors. The CRV has 181k on it. Owned it since it had just 15k.

Not sure if it's the braided stainless brake hoses or the rotor with the Akebono pads. The initial bite is aggressive. Leaps and bounds better than I was expecting.

Now that is a nice looking brake job!

 

[3800Series]

Sorry misclicked something, I apologize I hadn't read the post I seen the shim, looked up and seen CRV. Felt very confident that is what it was should have read.

But yeah the shims tend to stick in place for the most part.

They do. The bent tabs tend to 'bite' and keep them in place. After 15+ years and if the bracket gets removed a few times, I've seen them loosen up enough that they fall out. I suppose you could try bending the tabs a bit but I just put a dab of Syl-Glyde between it to hold it like glue.
