Default Creaking noise coming from brakes...?

2017 WRX - 23k miles - stock suspension - 18" Hyperblue STI Wheels

Ive been dealing with this clicking sound (see video below) from my front left for some time. I can just sit there with the car parked and itll make that sound all day. Seemed to happen almost right after I put on the STi Wheels. I brought it to the dealer, they replaced the top strut mount and steering rack (after literally begging them to cover it under warranty).

Long story short, I picked it up yesterday after the steering rack was installed, get in it and the sound persists. I go back to the service manager he says "impossible" we go out and it immediately makes the noise. After messing with it for 15 mins, he pushed on the back aluminum plate behind the rotor and it quiets the sound a bit. He gets the tech and he says, "im working on another wrx right now thats doing the exact same thing, put the E brake up, take your foot off the brake and do it". Sure enough the sound went away.

Tech seems to think its something with the wrx calipers. I could take em apart, clean em and they will be back to normal for another 10k miles or so. Its just strange its just the one caliper...Anyone else having this issue?

Could be about 50 different things. I'd just replace the caliper and backing plate (heat sheild) and be done with it.

Or, take it apart, clean everything up, grease the slide pins, put a small bend in the backing plate to stiffen it, put it back together and see if it happens again.

It doesn't make any sense if the car is not moving that the brakes are making this sound.

When you say " he pushed on the back aluminum plate behind the rotor and it quiets the sound a bit. " are you talking about the dust shield? You don't really need the dust shield at all.

It almost sounds like some kind of pump issue. It sounds likes a pump or something is cycling. The sound is rhythmic and repeatable.

Does this sound come only when the car is running?
Will it make the sound if the car is off and you out your foot on the brake?

My suggestion is to remove the new wheels and go back to your previous wheels and see if this noise persists since you said this seems to have started right after you switched wheels.

Come back and let us know what happens.
