Hi y'all, my 2014 hybrid XV only has 34k and started making a sound about a year ago. It is a one time click/clunk sound that comes from the front end of my car when I come to a stop, particularly when I turn the wheel to the right slightly while stopping. It also isn't as loud right now as it was in the video, perhaps it needs to warm up more. The dealership says it's from my breaks and is perfectly normal. They say as I back down out of my driveway and come to a stop the front break pad has normal play in it and slides back. As I come to my first stop it slides forward making the click/clunk sound at the end of the video. I just wanted confirmation of this or what it could be. Thank you in advance.

Pretty sure I'm getting a similar click, but it happens a little differently for me. It's usually when I'm turning right sharply, especially when uphill... So, that kind of sounds like the opposite scenario, but maybe the same thing since the dealer said it is normal play.

I noticed it a couple years ago actually. I asked my dealer and they said that it was normal. It seems to be worse now, I think. And it sounds kind of cheap - like, passengers might be a little worried that the wheel is going to fall off or something...

I'm going to have it looked at again next time I get an oil change, just to be safe.

I am really not much of a mechanic and unfortunately was not able to have the mechanic show me. I am also assuming my breaks are fine since they didn't say anything about them needing to be replaced. I will most definitely have them show me when I do have them replaced though.

well, ok then...look at the pic:

thats one whole brake with the caliper (the thing with scion written on) moved out of the way, the other red part is the caliper bracket, its not the one in the crosstrek but the concept is the same.

you can make out one of the pads (that rusty looking thing in between the caliper bracket)
as you can see the pad has two ears that go into a groove of the bracket, thats because the pads need to slide in to grab the rotor and stop the wheel from turning and slide out, away from the rotor, to let the wheel go.
If you look carefully between the red part and the pad, where the groove is, theres another small piece of metal, its an abutment (or antirattle) clip, heres a closeup of it:

Theres one on the top and one on the bottom, heres a pic of the pad ear and the clip alone:

when you buy the pads there should be the abutment hardware too, a set (for two tires so 4 pads and 4 clips) looks like this:

Sometimes there is some play between the clips and the pad (various reasons for that or the clips get forgotten) and the pad moves a bit up and down and so it slaps onto the braket making noise when it grabs the rotor.
That can be the click clack. It can be resolved using new abutment clips and some of them are even coated to quiet down noise.

Another source of the noise can be another couple components: the slide pins
Image

There are two of them one on top and one on the bottom, the caliper attaches to them, you dont immediately see them because they are behind the brake, on the car side.
The slide pins also slide in and out, thats what allows the caliper to move so that it can squeeze the pads to brake and then let them go.
If there is play at the pins then again you have movement and that same slapping noise. If one changes the pins the noise goes away.

If with the car raised up and the tire off and brakes on (somebody helps you or using a stick) you grab the rotor and turn it you can spot where the play is. Thats what you want the mechanic to show you (or if you check by yourself)
Personally the only cars where I found that play as "normal" is in race cars, the crosstrek isnt a race car. Out of the dealer lot the brakes dont slap around, they shouldnt later on either.
