Hey y’all I could use some help diagnosing and remedying this issue with my 2014 Acura MDX. I have noticed only during the night and early morning (never during the heat of the day) I have a very LOUD groaning noise whenever I brake at low speeds, I never hear this noise at high speed. I had my friend walk beside my car as it brakes and it appears to only come from the front passenger side caliper. I have not checked the pads or anything yet but the circumstance of the noise occurrence has me stumped. Any and all help is appreciated thank you all.
