Nope. My 2nd gen Cummins pedal was stiff and took much less effort to slow the beast. The ‘21 gasser stops but not what it should be IMO.

You're doing it wrong
Mine is a cummins i hop between the 2 trucks sometimes 3-4 times a day and the pedal feel is the exact same.

My 21 PW stops great. I don't mind the pedal feel. I was once driving on a dark highway at about 65-70 and had a deer run out in front of me. Had to absolutely dynamite the brakes and I couldn't believe how quick they slowed the truck.

I don’t think the brakes won’t work and it’s likely just getting use to the vacuum boost brakes again.
I’m at +72,000 miles and the front brake pads are going to need replacing this year, so new pads may affect what I feel.

My '23 2500 gas breaks feel real soft. I thought there was air in system as they would pump up. Came from an 05 diesel that I put 245k miles on, so may be a factor, but still doesn't feel right. Tried a panic stop and went 5-6 ft past where I expected. Dealer says all good.
I know that I am reviving an old post, and I have read through all of the comments on this issue on multiple forms. With that said it doesn't matter if it's a hydro boost or a vacuum boost The pedal should be firm and it should engage at the top. I have driven and owned several brand new HD trucks both gas and hydro boost and when working correctly they should be firm and at the top of the pedal.
So I have done some digging and this truck which is a 23 2500 with the 6.4l has obviously the same issue. It has been to the dealer and they confirmed the pedal didn't feel right so of course they bled it and actuated the ABS. The pedal firmed up until it sat. Once I picked it up it was right back to having a bunch of pedal travel. I have bled them myself before the visit to the dealer and actuated the ABS on a dirt road. All results are temporary as the pedal reverts right back to being soft until about halfway.
After a few weeks of research I have concluded that this is a software issue. To my knowledge RAM does not have an update to address this issue. The computer is operating off of algorithms based on driving habits and speed, all of which contribute to the pedal feel. Turning on cruise control and using the brakes to disengage it automatically firms the pedal up. Even three or four cycles through the brakes after cruise has been disabled. I disconnected the battery terminals and let it sit for about 5 or 10 minutes and I got 4 days of a nice firm pedal that engages up top. After that it went back to the inconsistent soft feel.
It is an extremely annoying engagement but what seems to be the more permanent fix is to make the software algorithm think that you're always about to jump on the brakes. After many breaking cycles coming off the gas rapidly and touching the brakes has given the pedal the most consistent feel since owning this truck. The fact that engaging and disengaging cruise control and disconnecting battery terminals changes the pedal feel just confirms that this is a software issue. The pedal should be firm and up top and it is as long as the algorithm has a reason to keep the pedal up high. I've had the most consistent luck with removing the foot from the gas pedal quickly and just easing on the brake pedal.
Ultimately, the only way RAM is going to address this issue is if enough people bring it to their attention. Personally I have created a case number with corporate. That was done before I came to the conclusion that software. There isn't a breaking system on the planet that would retain enough air to have to run that many bleed cycles unless it's sucking air from somewhere.
We're talking about the gas engine braking system. The 6.4 l 2500 has excessive pedal travel Right off the lot. Kind of crazy to me that this has been going on for several years and they haven't come out with some sort of a software update.

I have a 2024 6.4 2500, and this has been my experience as well.
I don't have remote start, so I will start the truck while standing next to it in my ski boots (its in park, with the parking brake fully engaged). I can reach in with my left hand and depress the brake, and hit the starter button with my right hand. Just using my hand, and with no leverage or mechanical advantage, I can depress the brake about half-way to the floor. That seems a little bizarre, but the truck brakes just fine when I'm driving, so I haven't taken it to the dealer.
It's already known that it's software and it's by design. Ram is not going to alter the programming.
Well I may continue to make a stink about it with the dealer and corporate themselves. But in the meantime my immediate solution to the problem, just unplug the sensor at the booster. You won't have electronic stability program running but that's the problem. That program is creating that excessive pedal travel complaint. Wow this may be by design or they don't want to own up to a not having the best algorithm for their software the brake pedal should never be inconsistent. Every time you touch the pedal it feels different than the last. I'll run it with an ESP light on before I continue driving it as designed.It's already known that it's software and it's by design. Ram is not going to alter the programming.
You’ve got it backwards. The software isn’t causing more travel most of the time, it’s reducing the travel when ACC is engaged by “prefilling” the brakes to bring the pads closer to the rotors. It’s basically stepping on the brakes part way to reduce reaction time, because the system assumes that while ACC is running that the reason you’re most likely to step on the brakes is a panic stop. Disabling ESP and ACC will make it so it’s never “extra firm”.
Yeah it didn't work. At least not for long. I'm a little obsessive compulsive when it comes to stuff like this. No vehicle that I have ever driven has ever had a brake pedal like this unless it had air in the lines. This definitely does not have air in the lines. And I guess in a way I'm desperately trying to figure it out since it has been mentioned before that RAM won't address it. And I really don't want to have to go get another truck. It is the single most annoying thing.
I pull a seven or eight thousand pound trailer daily before there's water in the tank. The excessive pedal travel causes trailer brakes to engage way more aggressively than it should as they are progressive and it's picking up the pedal travel. Same trailer different truck didn't do that. I am not currently in a position to let it live at the dealership since this is a work/business truck and the season is about to kick off. I did make a case with star but talking to a service writer is not going to be good enough. I'm going to need to talk to a technician.
I will agree though, the brakes / truck will stop. My biggest complaint is that the pedal will travel halfway before brakes engage and 15 minutes later it'll be nice and firm. Then the next time I have to touch him it's back to being halfway or more. The inconsistency is driving me crazy and it makes the truck feel like it won't stop. Trailer breaks definitely should not be doing so much work but it is since half the pedal travel there's no engagement from the truck brakes.
In my mind and all of the years that I've been working on vehicles brakes never acted like this in the unless there was something wrong. If this truly is by design someone messed up bad. Especially since so many are complaining about it.

This lawsuit settlement might be just a smidgen related to the brake issues, but it's on Gen 4 trucks...

So I have found the fix for this issue at least for my truck. After having it in the dealer several times and they did acknowledge that this is not normal for the feel of the brake pedal. They ended up replacing the ABS block module and motor with no success. I went through my entire braking system myself since this truck is out of warranty by a thousand miles on the bumper to bumper. I inspected all brake lines I even removed the master cylinder with no visible leaks or issues. Come to find out the rear calipers are hung up. The calipers are aluminum and the Pistons are steel so they're going to corrode at different rates. I collapsed both rear calipers and remounted them and that has brought my pedal back to where it's supposed to be. I noticed that the front brakes were wearing much faster than the rears even on this truck with 38,000 mi. Way more than normal. Upon taking off the wheels you can visibly see that the front rotors have been getting too hot. There was a gap between the brake pads and the rotor in the rear which is what caught my attention initially and why I decided to collapse the Pistons. Since doing so the brake pedal is normal and the truck feels 100% better. So if you're still having this issue it is definitely not a software issue or an ABS block issue. These ABS systems are not as sophisticated as we all think. They drive 100% of their information from the wheel speed sensors and nothing else. Although there is software there it's not complicated. So definitely go through take off your tires and collapse those rear calipers.

What year? My 19 don’t look like aluminum
Mine's a 23. They don't necessarily have to be aluminum to get hung up but it's definitely more likely given the non-ferrous metals. It's still worth a look. I think the 2021's and up are going to be aluminum.

There should be enough clearance in them but yes I know about dissimilar metals and the galvanic corrosion with aluminum and steel as-well as a sticking calliper.
