Brake noise when backing up - 2019 1500 DT

[NY_Sparky]

So, this is a new one for me:

Within a short period of time after buying my truck, I noticed the back brakes would make a terrible screech when backing out of the garage in the morning, as well as backing out of my spot in the parking garage at work in the evening. I just attributed it to new pads not being broken in. The rotors certainly aren't visibly corroding over a few hours.

15,000 miles later... it still does it every morning / evening. I leave for the day before the Wife and Kids are awake, so I'm a little self conscious about the noise in the morning. In the evening, it's just embarrassing - it's loud, people notice.

As the noise continued, I thought maybe this truck was a disc-drum combo rear like some of the previous models, and maybe the e-brake had some excessive dust in the drum. Upon inspection, it appears the e-brake is mechanical on the caliper.

I've done some intentional brake dragging while backing up while on high idle, but it hasn't helped, just made alot of noise. I am getting pretty adept at jabbing the brakes repeatedly while backing out in the morning to minimize the screech.

Between the back up brake assist constantly threatening to lock up my brakes because it thinks I'm too close to my garage door track, and the brake noise when backing out, it's making for quite a start to the day.

Anyone else getting this? Any suggestions that aren't "spray the pads down with Disc Brake Quiet"?

Thanks!

The first thing I would do would be to remove the rear wheels and visually inspect the
wear indicators/noise makers on the brake pads and see if they are touching the rotor. I have seen brake pads with the incorrect length wear indicators riveted in place and they make noise constantly.

It's a good thought, but it isn't that metal-on-metal noise that the sensor / wear indicator makes. I realize I described it as a screech this morning, but that probably wasn't the best choice of words. Sitting hear trying to coming up with a good way to describe it is tough. I guess the analogy of a brake drum with alot of dust in it is still pretty good. Maybe a howl is a better description.

This is the first ram I've had with the mechanical e-brake on the caliper, so I can't help but be a little suspicious of that. Also kind of funny to look back at the e brake technology changes over the years on my rams....

I heard the same type of thing on my 2019 Limited. I'd call it a howl like a sad dog. It only seemed to happen when I was backing out of my driveway in the morning. I never heard it on our 3-month trip to Vancouver and totaled the truck soon after we got back so it was never diagnosed.

Go do some very aggressive braking, almost to the point where the ABS kicks in on dry pavement. I'm guessing you have a shiney spot in the brake pads somewhere. If that works, quite riding your brakes. These trucks will stop you in less than 130 ft when going 60mph. Braking lightly while driving around the city isn't saving your brakes, it's polishing them.

 

[NY_Sparky]

I'm not saying your wrong, but some points that may contradict this:

2003 Ram ~ 130,000 miles, original brakes when I sold it. To be fair, it was a 5 speed, and just about stopped when you let off the gas. Not exactly a fuel efficient machine.
2010 Ram ~100,000 miles, one set of back pads (I blame the stability control chattering from me being a hooligan in the snow, I threw a pad, it wasn't worn out)
2014 Ram ~90,000 miles, original brakes when I sold it.

That probably points to a few things, I do alot of highway driving, and I don't ride the brakes. In fact I pulse them enough when stopping that I make my Wife seasick... I used to race everything from snowmobiles to sport bikes... I know how to keep the pads grabby, and make them last.

The riding the brakes while back down a 100' driveway... I'm pretty sure cold brakes won't glaze the pads in 100', and I did that about twice to see if it did anything.

The brakes are really odd when backing up, they are right there on the pedal. It feels like when you were back in the drum days and you had them adjusted too tight, really grabby in reverse.

I will also add that the noise is gone once the brakes are warm (I checked it tonight when I got home). Wonder if they are using a new compound on the pads, and that is doing this?

I get that same sound in the morning when backing up. After backing out of my drive way it goes away. My brother has the same noise, I can live with it.

 

[johnts]

This is a common problem on these trucks. I believe there are TSB's out for a potential fix. There are other brake noise issues with these trucks also. Some have had their pads and rotors replaced multiple times before the noises stopped.

Thanks for the heads up. Sure enough, a bit of google work confirms this is a thing. Guess I should have done some more research before posting. Appreciate all the input here though!

The good thing about posting here is you get First Hand info to add to the google info you get ! This way when a dealer says I never heard of this before you can call B.S. lol Sucks you spend big bucks on your truck and deal with issues, Good luck and please Update what happens after the repair !

Hey @yakalong & @NY_Sparky

If you do address this with your dealers and you are in need of any additional support for that process, please do not hesitate to reach out! We are more than happy to get you connected with a specialist who can work alongside you and your dealer while in service.

This is a common problem. It's addressed by TSB05-002-19. Dealers are well aware of this as is FCA. The sounds only usually occur on cold mornings. In the TSB the sound is described as a low frequency moan or howl from the rear brakes when the brakes are cold. The TSB says all you have to do is describe the symptom and the dealer will perform the repair. The dealer does not have to replicate the noise.

2020 1500 4X4...Appears there are smart, informed and reasonable dealers/service dept's and then there are...THE OTHER ONE'S! My dealer (Santa Barbara, CA) said they knew nothing about it and could not find the TSB...So I emailed it them and then even printed it and took it to their location. Service Mgr. said that THEY would need to diagnose it themselves prior to any other action. To 'short-circuit' things I wanted to know if they had the parts (Moan Kit) on hand so as not to need the 'back & forth' and the reschedule routine...They would not even check if they had the parts. However, I did convince them, that I drop-off the truck the night before so that the brakes would be 'cold' for the evaluation. So, we'll see....Oh Yeah, and my 3yr warranty expires a few days after this evaluation scheduled for 9/21/23. So, I will probably be installing the MOAN KIT myself.

 

[Runaround]

I know someone that had that problem on, I’m guessing a 2021 model and he took it to the dealer and they did something with the emergency brake.
So you are correct about it being the emergency brake. They are electronically operated on those trucks.

Well, the dealer duplicated the symptom and installed the Anti-moan kit (They didn't have it in-stock..so took 2 days). As a TSB is 'not a recall' this may have been a full-charge expense if it wasn't still under warranty, or you can buy the kit (cheap $60+) and install it yourself (looks simple). My trucks Moan noise, at times, was loud enough to awake a sleeping neighbor. Kind of a 'harmonic howl' that was ear piercing sometimes.

 

[Bravo619]

Also I can vouch for this anti moan kit . That it does indeed fit the 2021 ram 1500 unlike what the dealer and the aftermarket seller said ! So just because it says it won’t fit your vehicle don’t believe everything you hear.

My first thought is that the brakes have been replaced with el-cheapos. I wonder if someone forgot to ask themselves what the lives of the passengers are worth when looking for the "cheapest thing possible" for new brakes. Not saying they did this, but, I am curious.
Secondly, did the "Mechanic" do diligence by bedding the new pads to the rotors? This is done by driving the truck up to 40-50 MPH and gently applying brake pressure and letting the truck slow down to under 10mph very slowly, then releasing the pedal, and repeating this several times, allowing about a minute to let the brakes cool between applying them. Afterwards, slow gentle braking where practical, for a couple of days will finish the burnishing.

Afterwards, drive normally. As a professional, NONE of the premium brakes I install EVER squeak after I install them and do this procedure. When the customer insisted on the cheap brakes, they squealed regardless of the bedding process.
