RE: truck swerved with hard braking

Curious if there was a crown in the road. You mention you were mid pass, so between lanes. If there was any rise in the pavement between lanes or grooves where the tires track and you hit the brakes hard on one it could cause the wheels to pull to one side. This very well could be. I believe that I was still changing lanes when I hit the brakes. As soon as I cleared the 18 wheeler enough to see that the left lane was blocked I braked. Someone else sent me a private message saying the same thing, that the swerve while braking could have been caused by a groove in the road. I really don't know but it seem logical that I may have also started to move back to the right lane as I was braking. That would be the reflexive reaction. Seems the moral of the story is BE MORE CAREFUL. When passing an 18 wheeler don't assume that the left lane is clear, because there is a blind spot where there could be a slow vehicle in the left lane. Then being in the middle of changing lanes while starting a hard brake is that much worse.

RE: truck swerved with hard braking

Well the truck is back from the dealer and I can report results. I was told the mechanic inspected the brakes and there is plenty of life on the pads (10mm) and the brakes are functioning properly. So they did no service. I had said might as well rotate tires but only if you need to remove the tires to check the brakes, otherwise the tires are not due for rotation. I was told they did not need to remove the tires. That they were able to inspect the brakes without removing the tires. This surprises me. I thought tires needed to be removed to inspect brakes. So the braking incident remains a mystery. Several theories were presented in the responses here that it could have been an anomaly. I will do as some suggested to find some open road and try some hard braking to see if I can reproduce the problem.

RE: truck swerved with hard braking

Have the brakes ever been serviced? If not you are way overdue at that year and mileage. I have similar mileage on my ‘17 and they have been serviced twice. The manual recommends brake service every 20k miles, more under heavy duty use. Was this 20k miles of highway, city, or mixed? I have 42k miles almost all highway. I am surprised you need brake service every 20k miles. The RAM manual says to check the brake pads every 20k but I have been googling brake work and that 20K is a check but pads usually last longer than 20k. Also from my recent google reading "brake service" can mean many things. New pads, or add rotor, or add caliber. Possibly bleeding and replacing fluid. What service have you needed?

RE: truck swerved with hard braking

How much do you drive the truck unloaded vs. loaded? If mostly unloaded and you load the camper and slam on the brakes, the piston in the caliper is travelling to a spot it likely has never been before. It doesn't take much for the piston o-ring to grab or lock onto a bit of trash. How does the truck handle braking now? Does it feel like it is pulling to the side? Did you have a recall on the front suspension, to align it then weld it in place? The miles on the truck are 96% loaded (and almost all highway) and 4% unloaded, so this might be a good theory. The braking handling other then this one incident is fine (good, never a problem). No pulling to the side. There has been no front suspension recall.

RE: truck swerved with hard braking

Understood, but with respect, you are allowing the traffic to dictate how you drive and 'push' you into an unsafe situation. You are trying to make an excuse for why you were in the position of needing to do the hard braking that you did. Lakeside Please read what I said in my post again. I said that I was driving 65 mph or less when the braking incident happened. Then as an aside I mentioned that I know this because I always drive 65 mph or less unless in heavy traffic. As far as going faster because of heavy traffic. At times it can be a trade off of increasing speed or having a line of cars in back of you all trying to swerve into the left lane around you. There is danger either way, going faster versus unsafe drivers around you. I don't know, I assume that speeding up to 70 or 75 in the right lane on a highway to keep up with traffic isn't unsafe. Is it? I have a dually truck with a lightweight camper and the truck handles fine up at 70 or 75. I more stick to 65 because of gas mileage. I find that the jump from 55 mph to 60 to 65 definitely hurts gas mileage. Going over 65 and gas mileage really tanks. If I am on an empty interstate I have chosen 62 mph as a sweet spot, or if I am in no hurry I may just go 55 mph and save some gas.

RE: truck swerved with hard braking

I am the OP. Thank you for all the comments. The truck is going in for service today and I am asking for the brakes to be checked. When I first posted I thought the answer might be that extreme braking with the truck camper loaded it is expected that you can drift. There were comments asking about what happened. It was on the interstate. I was in the right lane and I am sure driving 65 mph or less because that is fastest I drive with the camper loaded (unless I am in heavy traffic and causing a traffic jam with people trying to get around me I might speed up because it becomes a trade off of which is more dangerous speeding up or every car in a traffic jam passing you, as well as it being rude to block traffic). I was approaching an 18 wheeler that turned out to be moving very slowly climbing the hill. It was the choice of brake down from 65 to 25 mph or pass. There was traffic approaching me in the left lane so I actually accelerated a little to change lanes ahead of traffic and BANG there was another slow moving truck in the left lane which had been hidden by the 18 wheeler in the right lane. So I had to slam on the brakes. I was probably still changing lanes moving to the left when I saw the second truck. The lesson learned is to not assume that the left lane is clear when passing an 18 wheeler because there is a blind area. I suppose you have to assume there could be a vehicle moving as slow as the truck in the right lane so you need to keep speed and stopping distance the same as if you were to remain in the right lane. It was an unusual situation because usually when you change lanes to pass a truck any vehicle in the blind area will also be passing at speed, not also moving 25 mph. I have not had any other braking problems other than this incident. I don't think there is any pulling to the side when braking other than in this extreme incident. We will see what the mechanic says with the brake check. It could be that it was the bad alignment I had at the time which caused the drift when extreme braking. The RAM 3500 truck has been great no mechanical problems except for it turns out that it seemed it came out of the factory with bad alignment. From the start it took constant adjustment to keep in the lane. It took me 4 years when my tires wore unevenly to discover this. This is my first big truck. I asked many people in campgrounds about the lane drift and the answer was that is how a truck drives. One guy in a campground had the same truck and had the same problem. He said he read in truck forums that 3500 4x4 is known for this lane drift and there is no alignment adjustment on the 4x4. Turned out incorrect there is an alignment adjustment. If others in truck forums were having the problem it could be trucks were being shipped with bad alignment. With the new tires (good quality Michelin tires versus the original factory tires) and alignment the drift problem disappeared.

RE: truck swerved with hard braking

I am the OP. Thank you for the input. Something I thought of since I made the original post is that the truck had an alignment problem at the time of this braking incident. The front tires were wearing (very) unevenly. The outer tread on both tires was worn much deeper than the inside. I ended up getting a full set of tires and an alignment. The truck had always been hard to keep in the lane since when it was new. After many adjustments I finally found out it was this alignment problem. Since the new tires and the alignment the drift problem is gone. I'm wondering if the alignment problem might have caused the braking problem when I drifted lanes with a very hard brake. No need to jump on me. I WILL get the brakes checked.

truck swerved with hard braking

Ok, here is the story. I was driving on the interstate it must have been approaching an uphill. Truck in the right lane moving slow. Another truck moving up on me in the left lane. So I hit the gas to pass the slow truck in front of the truck approaching in the left lane, and bang there is another slow moving truck in the left lane in front of me that I hadn't been able to see because it was blocked by the slow moving truck in the right lane. I had to brake very hard. As I braked my truck swerved into the right lane. Lucky there was nobody beside me. This was with my 2016 Ram 3500 dually with the truck camper installed. Would this swerve indicate that there is a brake problem, so that I should have the brakes checked? Or is this just what happens with a truck loaded with the truck camper when braking very hard? That was the hardest I had ever hit the brakes. Also that I have 42,000 miles on the truck. However almost all of those miles were highway driving. I am taking the truck in for an oil change and debating whether to ask for the brakes to be checked. But I would rather wait until the next oil change because removing the dually tires to check the brakes is a job and I just put new tires on the truck so I don't need tire rotation. Next oil change I could do both tire rotation and the brake check. I will have 50,000 miles at that point. I now see that the manual says brake linings should be inspected every 20,000 miles. But it is a big difference in brake usage city driving or almost all of my current 42,000 miles was highway driving. Opinions? Can I wait until the next oil change to have the brakes inspected? Other than this one experience with the slow moving truck the brakes have been fine.
