Thanks, first time I’d heard of it 
I’d love for you to hear my truck when I hit full jake. 3408 cat with 8inch straight pipes. I’ve set off burglar alarms in small towns from vibrating the windows lol

Thanks matey, who’d have thought that a borderline troll thread would turn into a meaningful exchange of motorsport knowledge.

Makes a hell of a noise also,outlawed in many towns!!
Actually the engine brake is a rediculously simple affair. It’s just a butterfly valve on the exhaust manifold activated by a small air piston. This piston works of either a foot button or automatically. You can set it to work on over run or to supplement braking. It only slows you a little.
It’s a bit like pushing a potatoe up the exhaust.
At least, that’s how it works on my truck.
Sounds like you are describing an exhaust brake, which is really quite different from a Jake Brake. Exhaust brakes are quite simple, but don’t have near the effect in braking force that Jake Brakes do. Jake Brakes actually manipulate the valve train functions. They are extremely loud and therefore illegal to use in some places. Somewhat akin to the desmodromic valves used on one very early Formula One car and Ducati motorcycles to eliminate valve float when your turning close to 15,000 rpm.
When I first passed my Class 2 (UK) I got a new truck a few months later and kept reporting a sudden lack of power a few times a day, mainly when I didn’t want it to, like at roundabouts Put into the garage a couple of times but they couldn’t find anything wrong. Eventually worked out that I’d been unknowingly resting my foot on a totally hidden exhaust brake (didn’t know what that was either).
At least with Forza there’s only 1 type of brake, the left trigger, OP, stick it on assisted if you can’t brake in time.
So that’s what that sound was. I was driving on the highway a week back when I heard what sounded like a vintage war plane. Looked up, no plane. But there was a truck coming from the opposite side about a quarter mile away behind a camry and an older jeep suv.
Getting back to cars and Forza, that reminds me of a couple of years ago when driving a truck in Scotland on a B road and I nearly pooped my pants when I was overtaken by a “plane”. Turned out to be a Nissan GTR and I could still hear it even though I couldn’t see it!
Your brake pressure is too high.
The common issue that people have with how the game is, generally stems from simply ignoring the TUNING aspect of the game.
I have been a Photographer for nearly 30 years, and I know that you do not expect a picture that I take, to be the end product. It is not a Polaroid, or a #NOFILTER on snapchat… Talking about the next level of photography, where you are trying to capture what you saw, not what the camera decides to show you. All photos need to be developed. You VERY RARELY will have a picture that is perfect, straight out of the camera. I would say something like 1 in every 100,000 photos, needs zero adjustments.
This is that same idea, with any sort of vehicle. You don’t just slap Brembo calipers on a car, and expect it to act like a race car. You don’t throw Alba shocks onto your quad, and expect to out handle everyone on the track. And you don’t Throw a Corsa Exhaust on your Camaro, and expect it to do anything special aside from being loud.
These all require fine tuning.
If your braking is off, consider these two factors… How much tire friction is there… What TYPE of brakes are on the vehicle. Adjust your pressures, and your balance to offset the WEIGHT of the vehicle… If the Vehicle is 60% front heavy, you probably should make your brakes Bias toward the REAR higher than the front.

Thanks for all the input guys.
I’ll just add my 2c in here as well. IMO it’s all about perspective, what you see on screen is perceived differently to what you see in the real world. A Prime example after this is when I got my old man (who is also a truck driver, since the ripe age of 14) to play on my racing rig. When playing on a screen, he flew off at the first corner, “the brakes don’t work” he said. Continuing to Finnish the lap and failing at every braking point I then got him to drive the same car and track but this time in VR. And the result was night/day, he broke way before he needed too and didn’t come off the track once.
The only thing that changed was the way he was perceiving what was happening as VR is much closer to reality than a screen ever will be.
Forza may not be exact but it is pretty close to reality, its just harder to get that level of experience and immersion because we are all limited to perceiving it on a flat screen
Edit: g-forces also play a huge part

Can’t add any input on the whole trucking side of this thread other than big diesels sound glorious and jake brakes are absurdly loud and i hear them 26 times a day because i live in the hills of Pennsylvania surrounded by gas wells lol. But i can speak from the perspective of having driven actual cars irl that are in game on an actual track. The brakes work prettly close to irl but in real life you can feel braking forces, which makes a difference to me. The only thing about the steering and handling i can say is cars will understeer quicker and with more severity than irl. All of the physics are close but not perfect, i think its like 90% accurate. The biggest part is not feeling the forces you would feel in a real car.
lol
Drive the F1 car in the game, see if you keep your opinion.
Must be a troll or something.

not a troll, racing in 2D requires a big adjustment for most. as does driving a car with a controller…in addition, most people probably don’t expect ABS to make your effective brake distance 2x more than it should be
(i am speaking from experience btw; in addition to the limited sense of speed the notion that you’re driving too fast when you’re so slow overall is hard to reconcile).
lol That’s because ABS IRL doesn’t double your braking distance
What more proof do you need when it was first implemented into racing how well ABS worked and people were called cheaters for using it and it was outlawed from professional racing do you need?
And that’s when it was first created, it’s far better now. I think it increases the stopping distance by around 20-25%, not 100% as it does in-game. Furthermore, when you brake you do not have to cross the threshold to activate ABS but you aren’t really given that choice in game either.
Hey now, they don’t call me turtle 
for nothing. Don’t be picking on slow ppl lol. I’ll get the hang of it eventually as long as u guys don’t mind me ranting once in awhile and keep me straight 
@DEMIL0N James Bond,
Weight transfer has has been in since the first forza game, just look at the telemetry of tyre friction. The circle at each tyre represents the contact patch, when you accelerate rear tyre contact patch increases and front decreases, indicating that weight has transfered rearward. Same for braking and cornering, turn left and the right side tyre contact patch will increase and left side decrease which is exactly what you’d expect to happen. Weight transfer is there and works very well, power and wheel spin have nothing to do with it.
Okay now I can see it while my truck is trying to flip over whenever I try to turn in it
