Rear brake rotors after 30k miles?

[Jgrakla]

Hi all,
Newbie here. Please forgive me if I should post this in a different forum.
I was doing my 30k maintenance on my 2020 Ram Limited and noticed something odd with the rear brake rotors. Wondering if others have encountered the same. Looks like I have plenty of meat on the pads but seems like the rotors are galling. Seems really premature for such a thing with only 30k and on the rears no less. Pics attached. Any thoughts on if this is normal for these trucks?

Also i DO have that brake moan in reverse when first backing up in the morning.l that lots of folks complain about. I see there is a TSB for it with anti-moan kit that can be installed but it doesn’t seem like that would be related To this problem would it?
Thanks all!

That looks pretty normal to me, as well. I have found on my cars and trucks that the rear brakes tend to cause more problems than the front. There are several reasons: The front brakes use much heavier and stronger parts and they work a lot harder. That probably keeps them looking better as they are constantly being resurfaced. Also, sometimes the manufacturer puts substandard pads on the rear to save money. If it bothers you I would put on a more expensive, metallic or ceramic pad.

Thanks for the input. I agree the photos don’t look too bad. Some of those streaks looked worse in person. I could catch my fingernail on them. It wasn’t a smooth shiny surface like the fronts. Guess I’ll just check again next maintenance.

All of my rotors on my vehicles have looked like that at one point. I agree with normal. Maybe take another look in 10k.

mine looks like that with just 2200miles and 4.month old....the service.guy at dealer says they need cleaning... lol really a 4 months old truck with only 2200miles...

It's not an issue unless the rotors are warped or too thin. The scratches look like some road debris got into the pads. I've had this happen with brand new rotors and pads around 5k. Just keep an eye on it to make sure it doesn't get worse.

I agree, looks like maybe some road debris got caught in pads.

One thing you can do, or a couple things actually, brake harder more often. Get some heat in them, but don't sit with brakes on after getting them hot. That will cause uneven brake pad material to build up and is what most people experience when they say their rotors are warped.

For a immediate help, look up brake pad bed in procedure. Find a long straight road with low traffic and perform that. If you have any slight pulsing in the brakes, or uneven discoloration on the rotorsz this will clear all that up

I don't know if related but these trucks have "Rain brake support" where the brakes occasionally drag the pads when wet in order to keep pads dry.
I don't like the sound of that.

I mean, if the brakes are adjuster properly and sliders are greased, there should be enough friction to keep the pads warm in regular driving without needing to apply pressure at any point. And unless you have the rain sensing wipers, how would the truck even know it was raining to need to do that?

I'm not sure but I saw this on the standard equipment list so I know mine has it.
I had 75,000 miles on my '02 before my first brake job and still could have gone more. I don't see that happening with this system.

I too was curious too how it knows.
I found a you tube from a 2017 Jeep video with the system. It states the system is active when wipers are on wether auto sensing wipers or standard.
I'm glad I use RainX, rarely use wipers.

It's amazing what these trucks know. My brother forgot to plug his trailer lights in once with maybe a thousand pound trailer hooked up. The truck stopped, and gave him a warning, when he took off. I saw a post on here where someone said his truck had the rain sensor, but he didn't have the option, and wanted to know if he could add it, being the sensor was there.

I had no idea RBS existed, so I looked it up in the owners manual. The OP has a rear brake issue, which is completely unrelated to RBS.

Looks like there was already a thread about the braking system talking about this in 2018.

Brake Options

My window sticker just became available and I noticed 2 things were listed that I have no idea what they are: Ready–Alert Braking and Rain Brake Support. Anyone know what these are/do?

Good thing I don't put my wipers in LO or HI, and I disabled the rain sensing wipes, because it's way too sensitive.

It would take what, .10 seconds to remove all water when hitting your brakes in the rain? LOL
