Car is and ek hatch. lowered with koni/neuspeed sports,asr brace itr sway bar and oem end links. Ive replaced the rear trailing arm bushings serviced the rear drums and replaced the endlinks.
The noise only happens in moderate to heavy brake applications where i get some weight transfer to the front I hear it but under light braking no noise is made. I have clocked the bushings the noise goes away but comes back a day later.

What else could I check remove or replace?

 

Install a stereo and turn it up

Are you using any polyurethane bushings? Those tend to squeak when not greased at proper intervals

 

Turmning up the music is good, I just roll down my windows.lol.

I kinda gave up on chasing down little noises in cars I've modified, eecially Civics.

 

No poly bushings other then the sway bar ones I did notice that my factory rear lca bushing for the shocks are pretty much toast the other night im able to move the shock side to side a bit so ill try that.

 

That is no good.

Try that, also check all of the other bushings.

If that doesn't fix it. Do what I did. Install 2 12's, 2 amps and turn it up
