Thanks to anyone that has suggestions.
I have a 2009 Nitro RT 4x4 that makes a loud creaking/groaning noise when releasing the brakes.
I did a complete brake job by replacing the calipers, rotors and ceramic pads all the way around the car.
I used high end ceramic pads and Mopar calipers.
The noise went away for about two days and now it's back as loud as ever.
Anyone else ever have this problem and find a fix for it?

My wife can be backing out of the garage and I can hear the creak from 100' away. It is seriously annoying. I' seen other posts that say this is normal. This is no way normal. The car never did this when it was new. There has just got to be a simple answer to this. I wonder what the difference is between the factory pads and my ceramic pads are. I would really hate to buy Mopar pads after shelling out $180 for new ceramic pads. My gut tells me that if I do that it won't make any difference. Maybe I should try bleeding the brakes again. It did shut up for 2 days after the install/bleeding. Good Grief.

Did you use a good brake caliper grease on the sliding surfaces, and especially on the backs of the pads, where they come into contact with the calipers?

Yes, I used grease as you described.
This makes absolutely no sense to me.
I've done many, many brake jobs in my lifetime and consider myself very good at it.
Never had this issue before.
Am I the only Nitro owner facing this?

still pondering

Thanks for your reply Mr. Heat.
The creak is loudest when the car has set over night. The creak is less prevalent when the car has been driven for a while and pads/rotors heat up but the noise never goes away. So, my first thought is that the ceramic compound is causing the pads to stick to the rotors as the car cools off over night and then frees up somewhat after driving and they heat up which makes sense me. What doesn't make sense is that I have multiple vehicles that all use ceramic pads and I have never heard a noise out of those cars at all. In my opinion, this is not normal as some people say. If my truck can be made to brake quiet then my Nitro should be able to be made to brake quiet as well. I bet there is a simple fix for this. The part that's not so simple is to find the fix.

Thanks again for the reply. Yeah, I've seen the damper before. That's really for noise heard when applying brakes. The "creak" that I hear is heard mostly when I take my foot off of the brake.
Here's a YouTube video that plays the exact sound that I hear.

CREAKING/GROANING SOUND WHEN RELEASING BRAKE

By changing out literally all the brake hardware and lubricating the slide pins and cleaning and lubricating where the slide pins go in the caliper mounting bracket, I've done everything I can think of and then some. Still have the dreaded creak.

 

[cmm47172]

Oh, And I realize that I can make that sound if I let the call creak forward slowly while applying light pressure to the brakes. Any car will do that. But that's not what I am doing. I can be at a stop and quickly and completely release the brakes and hear the loud creak noise. Only on my Nitro do I hears this.

Anyone have any ideas here? I've replaced everything calipers, rotors and ceramic pads. The pads I replaced twice with different brands. Is it worth the time, effort and money to buy more new pads but get Mopar OEM pads this time or switch away from ceramic to semi-metallic?

 

[cmm47172]

It only happens when releasing the brake?

My brakes squeeled like crazy when I bought my car. Replaced the rear pads w/grease on the backsides. No issues now.

Yes, it only happens when releasing the brakes. Very annoying.

 

[cmm47172]

I'm still dealing with this stupid creaking noise when I release the brakes.
Seriously annoying.
I'm thinking of doing a complete brake job all over again for the third time.
This time I thing I will use MOPAR OEM Brake Pads.
I'm starting to wonder if there is some other component in the system that could affect how fast the pad release from the rotor when the brake pedal is released.
Does anyone have a drawing/diagram of the entire brake system that includes the brake booster, master cylinder, vacuum lines proportion valve?
I want to go over this thing by every square inch.

 

[cmm47172]

i listened to the video clip, so it makes the noise even at a standstill ?

This happens with engine running, car in gear, then releasing brake pedal.
Brake pad, rotors, replaced twice. No missing parts. Guide pins lubricated etc.
Also replaced all four calipers with Mopar OEM parts.

 

[cmm47172]

actually high chance its the brake booster, that is the kind of sound a worn booster would make,
you should be able to hear the noise when you are close to either the ABS pump or the Booster,

The noise only happens when I'm in the running car and then release the break pedal while in gear. I can have my wife behind the wheel doing this as I stand outside the car listening for the noise. The noise is coming from the brakes, not under the hood.

 

[cmm47172]

thats the strangest sound i ever heard from the brakes,
whats your thoughts on bleeding the brakes again, including bleeding the ABS

LOL, I'm a magnet for strange occurrences.
Not sure what is involved in bleeding the ABS. I'm not real familiar with that. Tips Welcome.
That's why I'm looking for a diagram or drawing that shows all the pieces/parts of the entire system.
Other than that, The brakes have been bled multiple times starting at right rear, left rear, right front and then left front.
I have a good pedal feel and it stops on a dime.

Is it possible the creaking is coming from the parking/drum brakes?

Thanks for all the good info!
I've done a lot of brake jobs successfully over the years but I have never dealt with troubleshooting an ABS system.
I was thinking there may be a proportioning valve problem going on here and I'm assuming the Anti-Lock Brakes Module does the job of the proportioning valve.

It is defiantly not the parking brakes, I checked that thoroughly. Good thought though.
I hear the creak at the front wheels although sometimes I hear the noise at all 4 wheels.
I can make brakes creak in any car by slowly releasing pressure off of the brake pedal and letting the car inch forward or backward while maintaining light pedal pressure.
To me, that is expected, normal behavior.
That is the same sort of creak sound I hear on my Nitro when I quickly and completely release the pedal as one normally would under normal conditions.
Do you think it is possible that a faulty ABS Module or control unit could cause the caliper piston to not release the pads fully or quickly enough when releasing the brake pedal?
