Yes it´s that...didn´t have a clue on that, servo-brake booster, "freio" in ancient portuguese means "travão" also in portuguese, wich means brakes in english.
Thanks DragonCommando and tristancliffe 
"It works by releasing the compression before it has a chance to act as a spring" Makes sense...
Another question if i may....Is the manifold vaccuum (petrol engines) responsible for the extra force added to the braking system (in portuguese it is called a servo-freio)? The device wich help us in multiplying the pressure in the braking circuit...
Thanks guys

Guys explain me some thing,....please 
I thought (my knowlege of cars comes from driving, talking with friends, and what i can learn with guys like you) that car decelaration came from the inehrent engine/transmission/wheels demultiplication, as well from every other aspect that makes us burn fuel to accelerate; like tyre friction, aerodinamics, rollers friction, gravity......but i thought the major force actuating here(at lower speeds <60-70 Km/h) was the engine braking.....
I understand the concept of air compression inside cilinders actuating like a spring, if offers resistance to compression, and it can help counter effect the compression forces from cilinder to cilinder, one is compressing air but other cilinder at some point might be decompressing ñot only due to the fact of how a set of cilinders interconnected work but also because air wants to decompress expecially at those temperatures.
What is entirely new to me is the fact that we can have a specific engine part that is entirely or almost solely responsible for the engine braking.
I not saying that what you have written is wrong, by the contrary i ask you guys to explain it again but in a less technical language and in a more pratical terms, as i´m not english and i didin´t fully understood it
.
I also though that in trucks used water cooled brakes due to vehicle mass, type of brakes, and the gear box they use with lots and lots of gears....I though the course of the engine and the compression rate where the cause...

My english isn' good enough ti fully understand some things i read, too technical to some one that only "speaks" english on the net.
Well all diesel cars i've driven (road cars, not race), they all had a strong engine brake effect, Bmw 530d-535d-320td-740d-730d, Mercedes c220cdi-s400cdi-A170cdi, Vw 1.9Tdi 150hp, Audi, seat etc, except a fuc*ed up volvo i´ve driven...
And yes in downshifiting we can reduce the brake effect by injecting some fuel in cilinder(press gas pedal
)

I understand you point, but in fact when i try that in lfs the revs go up as it starts gainning speed, so clutch is engaged, and when clutch is engaged by lfs i can see the gray bar on the right bottom of the screen. So engine compression, shõuld offer much more resistence to the inertia the car is gainning.
------------------------------------------------------------------------------
I was saying that when it is in fact engaged in pedal (disengaged in mechanical terms) i can tell by the gray bar.
When it happens no gray bar is there, try it with a real car (keep in mind that lower cc3, lower resistance to movement-generaly speaking). In first gear in a descent let it roll until it reaches 5Km/h (ralenti achieved speed) or so, and then release your clutch pedal, youll see that it will offer much resistance to movement( even my little sister car does it and it is a 1100 cc3 fiat seiscento).
In LFS in the descent on the Aston circuit (i haven´t noticed a more angulated descent in LFS) if you try to mimetize reality it will fail miserably

. I don´t have a dedicated pedal to clutch nor assigned it to a button, so lfs intirely manages it.

I´ve seen mx-5do very cool stuff, like donuts, slides, and in those round roads(i don't know how it is called in english-a circle wich join some other arteries roads) it can go completly sideways still controlable...
I believe you, some cars do it more than others, compression ratio, gear ratio, weight, etc....varies, tyre condition is very important too...
But appart all this, please get in the xf gt at aston circuit and at the descent, stop the car at the beginning and in first gear lift the brake and let it roll, and see, the car accelerates way faster than it should do, with no inercia stored and the first gear engaged the engine should resist acceleration much more, try that in your car.
In my oppinion engine compression is has small forces actuating in the cars physics, i think it should be increased.

Im aware of the speed error, even so, you seem not to understand what i write or you dont remmember the gauge, the error is percentual thus increasing with speed, even so it reaches the middle of the clock, ok? and it´s not normal, my previous saxo wouldn´t reach there even in descents, nor 2 other´s i´ve driven. About the revs, i´m not sure but i think it has no error(at least not as muck as the speed gauge).
My rallenti is not steady, and my co2 values float, so i started punching the gas pedal to see if it normalized when revs went down, and the dude from the machine started showing me the revs indicated in the machine while i did it. But you are right normaly we only have to slightly accelerate till 3000 rpm depending on the car..

WRONG i said almost 8000 in my first post, so ...no point there...
Also i wrote the factory data, if you don´t know cars can go past redline (petrol) some more some less, only cars that i can´t get trough redline are the diesel ones (not tricked)...
If i ofended you...i did not meant to.
I haven't said full lock, i wrote almost lock, and wet tarmac and dirty tarmac you can bet my saxo whell spin front wheels slower than rear ones if i suddently lift my gas pedal in first gear...Why i did it? TO FU**ING compare with LFS, and it's not your business how much money i spend in repairs.
My saxo (my saxo not yours, or your friends) in the last annual inspection reached 8250 revs according to the guy who operates the machine(i don´t nkow what machine is, it just sits the car there and connects some cables to exaust, car battery and intake i guess, i nkow it can also measure gases)...AND in high way and Vasco da gama bridge i my kilometers counter passes max speed written in the gauge and reaches the clock
and the revs goes at 7900 -+ once again almost 8000.Now explain the ridiculous g meter, is that what you use when you are driving to know you still have grip???? do you carry one to school or work???? well i can tell when it skids or whatever, its called driving and predicting
The factory saxo brakes in 32 meters from 100 to 0, i have different discs, pads, and tubes(cables), and when i change tyres maybe i will give it a test
but in g forces i don´t know...Read topic from beggining, it is a comparison between real life engine compression versus lfs engine compression
Yes i shift UP at more than 7000 with this car and at more with others that achieve it...But i was talking about lifting gas completely in max revs in low gears...and it almost lock, almost, not full lock (first gear)...And this was only to compare real/LFS
tristancliffe you are implicative, the reason i posted that info was cause you didn't know a saxo could reach such revs, and more much more :-)....your name in my language means sad....

Edit:
1.6 (1587 cc) VTS - DOHC (Double overhead camshaft) 16 valve - 120 bhp/6600+-- 145 Nm/5600+- - 0-60 in 7.2 seconds - top speed = 127 mph 206 Km/h
MAN NO COMMENTS i own one, and yes it almost reaches 8000 rpm, 7750 altough in redline, and yes it almost locks wheels, want a video?

I said they should almost lock...not full lock cause engine will not stall...
I drive a lot in real life and very fast sometimes, i do not race professionaly or in circuits but i have driven many many cars from the weakest to exotics. Now in rear wheel driven cars some of you may have already noticed that in hard downshifting even without braking you can make your rear wheels spin slower then the front ones, its not a full lock but they do spin and can get you out of control almost as an handbrake.
I can reproduce what i said in the first post in a citroen saxo 1,6 16v (1076 Kg) in first gear at almost 8000 rpm it goes at 55 Km/h and if suddently release gas the tarmac better be good and dry or wheels simply go to only a bit faster than ralenti speed in less than 1 second...but the point is i think engine compression should be stronger while braking and when releasing gas even without braking...i think most you drive real cars and noticed that when you downshift you loose much more speed than in LFS...unless your engine is missing a spark

Engine compression
Don´t know if this is a bug or simply poorly simulated...
The XF GT is a 4 cilinder inline 2000 cc and it weights about 900 kgs, in the aston circuit by the descent i noticed that the brake effect from engine compression resultant of downshifting or lifting gas on high revs(well all revs) is almost non existent!!!! this as a tremendous impact on car behavior...i´ll try more cars and see if this is general or only xfgt...
In real life a prepared car with similar specs should almost lock wheels while releasing gas on max revs in first gear, and should have a tremendous brake power if done in 2 gear....

I see what you mean and you´re right, it probably wouldn't sell that much.
Can some one explain the metafore of saying too many cooks or ovens in english? as i´m portuguese and live here i don't really understand some funny talks....but i'm sure they are usefull posts
I wont.
They (Devs) as humans not gods
have done an astonishing job, i am not aware of the tricks in this kind of business but on a first a aproach it looks like 3 guys DONE this game, wich i think is the best sim in a pc. And in comparison to other games (of major companies) regarding a real and "truthfull" vehicle simulation it stands way above any other.(altough it looses in almost every other aspect-like visuals etc)The Concept of the game, the per-person produtivity, the compromise to reproduce reality above all other game aspects... Just think on this game beeing developed with countless zeros budgets, and they still in charge(the lfs devs)
Yes some games require a monthly payment and some an anual payment, but those games have dozens of servers owned by the game company and therefore have extra costs...i think there´s no servers owned by this development team(please correct me if i am wrong). Also those kind of games offer you some "extra" content to your game in a regular basis...and this game is very Alpha
I would not pay a cent more, at least without some MAJOR improvements....
In this post i gained knowlege of the fact they are only 3 guys i feel i have to say wow great work....and keep wondering what a major company could do if they followed the example o this 3 guys(what ever the example is :-) )

Is there a possibility to damage somehow a ffb wheel by increasing the ffb steps in the LFS config file to lets say 512? in a previous post in this thread i saw that someone sayd that if we increased the value from 128 to 256 the dfp would provide more feedback. My value was 256 not 128 so i increased it to 384, i'm not sure if its better so i was thinking to try 512 as the value for ffb steps?
I'm assuming it is some kind of ffb frame rate(in retrieving real time phisics information)...can some one explain what it is in concrete? and also wich values can we experiment and is it safe to do so?
Edit: i am using a dfp 900º
Thanks in advance

I would like some tips too on this whell drive force pro...just bought one and doesn't feel so good as i imagined, my thrustmaster enzo ferrari seems to have more natural responses, i starting to think it was badly spent money :-(...
pierre61 wich settings should we use both lfs and logitech gaming software?
Thanks

Yes, and i am happy with what i have right now.
I think you may have missed what i was trying to say...
Just remmembered, we will eventually have to pay a little extra to own S3 when it comes out?

ALPHA PRICE i agree with Ikaponthus... i have seen the aplha something being used as an excuse to basicly everything that an S2 user points as wrong or defectuous, so why not an alpha price....
Calling him spammer of the year or month or even a spammer is not fair...
Moderators what do you think in your oppinion? I think this thread makes sense, do you? I think that first of all a user has the right of starting a thread he thinks is usefull, don´t you(there are exceptions i know)? and if we do a search and we only get "archive" threads shouldn't we be able to iniciate a new thread?

Drifting is a sport, a very exigent one at least in real life...in lfs i tryed i'm not that good i can't get the feel of it through ffb and in a pc...
But in real life, it's a real sport, with real teams, real sponsors, real drivers, real spectators, real fans, real prices, real categories, and real etc....
Not every real racers can drift professionally, and maybe not every real drifter can race conventionally and achieve good results...
Whats harder? 2 hours of extreme G long. and lat. acceleration? 20 mins of rallying and jumps etc? 24 hours of LeMans? or 2 or 3 sessions of 3 min drift races?
Driftting is a SPORT and has no discussion i guess, and it may not be as hard as the most common races we ear about, but it can surrely intimidate a real F1 driver in terms of accomplishment, drift is what most drivers Fear except rally ones, you know they worship GRIP...
Im not a professional driver in real life but i do drive a lot and and many many cars, and i can tell you that in a controlled environment it's very fun to do corner slides, power slides etc..and it's when i feel the adrenaline pumpimg the most...
