Reverse clunking noise when you brake

Does your 5th gen crv make a clunk noise when you brake in reverse?

Im pretty sure its suspension related noise as oppose to brake pads.

i have a 2019 crv ex-l, 6k miles on it.

My 18 Touring does it but only the first time after it's been sitting a while, like backing out of the garage in the morning and backing out of the parking spot at work. Never really bothered me and it's been consistent so I haven't worried about it.

I've heard of something like this before; I think it was the rear stabilizer bar that was improperly torqued from the factory.

This was actually my thought as well... as it is very definitely associated with brake application in my case and only happens after the vehicle has been parked for sometime and everything is cooled down. Steering the wheel sleightly before pulling out of the garage does not trigger it, only brake application and only in reverse.

Update.....no clunk when backing up, turning left or right when backing up, or backing up straight/turning wheels and continuing back up from a stop.

I hear more of a “click” than a “clunk” when backing out of the garage. Pretty sure Traylaw has it nailed......pads shifting slightly in the calipers.

The clicking is normal, at a fresh startup on cold brakes when backing up in reverse. Probably the brake system self-adjusting or something.

The Clunking sound is different, but still appears to be brake related... at least in my case. I have never been able to get it to do it such that I can actually localize the exact source of the sound. It simply will not do it consistently enough for me to have my wife slowly back out of the garage while I listen for the source.

Since the brakes continue to work normally, and I never hear the clunk any other time, I'm not really worried about it.. just puzzled as to cause (which I honestly think Traylaw has pinpointed with his comment). :)

I think the sound is "heard" due to it being reflected off the garage walls, when backing out. Don't notice it once outside.

Over at the RAV4 forum (we have a ‘09), they say to reduce brake noise, turn the radio up.?‍♂

So we tied off on this thread a couple months back, concluding it was just the brake pads shifting. But I wanted to resurrect it as I have an update on the clunking noise from my 2017 CRV when turning the wheel while slowly backing out of my garage.

Turns out.. on my CRV it progressed over the last couple months to also doing it on slow right hand turns from a stop as well.

At first I was convinced it was just the brake pads settling.. but once the right turn incidence began, I went and did some careful low speed testing (2-5 mph) in a vacant parking lot, as well as parking, backing out, etc.

What I found was that it was not the brakes as I could actually get a fainter version of it if I simply let the vehicle pull forward in gear at idle and turn the steering wheel about half a turn either direction. So at that point it seemed I might have a loose component in the front end, or some issue with the EPS.

Took it to the dealer on Friday, and the service rep called out two techs who work on the front ends..and we all drove my vehicle around the parking lot, making left and right turns at slow speed.. and everyone confirmed they heard the same thing I did. So I left it overnight for them to work on.

Actual Problem: turned out one of the bolts in the suspension system on the right hand side was not at proper torque. Bolt was not loose, but not at proper torque... so it's good that I brought it in when I did, as it likely would eventually loosen. The dealer retorqued every bolt in the front suspension and sway bar linkage and applied Shin Etsu grease everywhere specified by Honda. All under factory warranty.

And now for the reason I love my particular dealer:
1) they also did the same to the rear end as well (even though there were no signs of any issues), just for good measure. Their assumption was if one bolt could leave the factory not properly torqued.. best check them all.
2) they also kept the CRV overnight and into the next day.. and different techs took it for a slow drive every hour or two to see if they could gain any recurrance of the noise. [I checked the trip data log on my battery monitor when I got the CRV back and sure enough.. they were taking the vehicle for a test drive every hour or two for about 5-10 minutes].
3) Called me to come get it once they were certain they could not longer trigger the noise, and also told me to be sure and bring it right back if the sound does reoccur in the future.

Anyway.. I wanted to leave this in the thread... just in case it can help someone else in the future if they get a similar sound from the front end and find it does not corelate with the brake pads settling.

Driving your car every hour or two for 5-10 minutes? Sounds like a series of food runs to me. :sneaky:

Thanks for your input again. I did not check the coil springs itself but i'll take a quick look at the top hat nut later.


My noise seemed to have gradually gotten worse. It is definitely louder now and it is bothering me. My gut tells me it is the steering rack since i literally checked each suspension bolt that i can access. None of them were even close to loose.

The coil springs rest in place on a set of rubber bumpers (more like pads, with little curbs really) ... which is where the techs applied the lube. If you look inside the wheel well.. you should be able to see them. I can clearly see the points where the techs applied the Shin Etsu grease.

That may, or may not be the source of your noise.. but it is worth looking into.. since you can easily reach and lube those contact points between the coil springs and their bumpers. If a spring was binding and popping at those contact points.. it would make a similar sound to the brake pads settling.

Good luck. :)

UPDATE:

Changed the front pads to Raybestos Element 3 and the knocking noise is completely gone. OEM pads were designed very loosely likely for less drag/higher MPG.

Phew...glad it wasn't some lose component in the subframe/suspension. Happy motoring all!

Thanks for coming back with the solution you found.

Clearly... your results confirm earlier comments about the common cause being the brake pads. :)
