What does a retarder do?

[CeruleanBlade]

I was just wondering

[UH-1]

Engine braking

[Der hippe Hugo]

so..similar to the motor brake (which has it's own option in the game) or is it somewhat different...
haven't really tested the retarder yet since I use the "normal" motor brake.

The Retarder slow down the Drive shaft from the Transmission to the rear axel !

Similar, but completely different. One uses engine compression for resistance, the retarder uses viscosity in the transmission. The major differences are that jake brakes (which is both a specific kind of engine break, and a generic term for all engine brakes in the US) are noiser, and banned in many US locations. The heat generated by an engine brake is in the exhaust, not the transmission. (Which theoretically makes them less desirable in hot cilmates, though if there is a long, hot descent where it's a big issue.)

They're called Jake brakes because the original idea was from a company called Jacob or Jacobs?
They work by partially shutting a butterfly valve at the end of the engine pipe, thus increasing engine backpressure and slowing it down. You often see signs like "Limit compression braking in urban areas" n such. The jacobs on Kenworths and Macks are legendary for their volume :D
I used to drive a Ford Louisville 9000 and its jacobs would stall the engine if I hit 'em when it was idling :)

Jaymo's link will provide the detail that is correct.

Room217au is wrong. A Jake Brake is not a retarder brake nor vice versa.
Jake brake is variation of 'engine brake'.. Wikipedia has a lot of detail that should
educate those interested on the various braking systems in use on big rigs.

I never said it was a retarder.
Jacobs make all sorts of braking systems.

A retarder is known as the thing that makes your car go 17mph (or kmp) for the longest time and then you begin to wonder if maybe the games glitched, you then continue to reset it 1,000's of times until your fingers fall of then you decide to see if anyone else has the same problem. Once you find out what you did wrong and what button to press to fix it you stop playing the game for 2 weeks because you get so mad that you didn't see that and you begin to feel like a ret*rd (the irony) (and the censorship), or you post about it and then real life truckers think your an idiot then continue to call you a "sissy" or a "pansy", then you tell them it's on the game and they continue to ridicule you about how trucking is hard and ain't no game. So once your done being called stupid a shining bright light tells you what it does in the game and what button to press to make it stop (since the ' looks like a . ) That's pretty much it in a (big) nutshell. Sorry if you already knew it by now and if I wasted about 1-2 minutes of your life.

Ok, i am going to upset people and purists with this but..... A retarder helps you brake. If a gearbox has R in the description then it has a retarder (normally most expensive gearbox). In the 250 + hrs i have on this game i have driven the whole time on auto box and never worried about things like this. Ignore it, choose auto, ie forward - neutral - reverse and thats it far as im concerned. Yes i know, i am not living the truck experience but i am quite happy using my 6 speed, manual diesel motor in rl and in a game i go for easy. IMHO thats all you need to know about retarders. :).

Basically a brake, Its useful for keeping under speed limits.

There's an old saying "Gears to go. Brakes to slow."
The great thing about ETS2 is ou can play it anyway you like.

You might be living the new truck experience; it's not like the automatic transmission and retarder are fictional, just uncommon. I believe currently manufactured trucks all disengage the retarder during an ABS event too. BTW, the automatic setting doesn't preclude manual use of the retarder. You can still turn it on/off on long grades.

I'm not living the truck experience either; I find the sequential gearbox makes it too difficult to skip gears while making it way too easy to get lost in them. Automatic is easier to drive with a controller.

If you do use a controller rather than the keyboard you can get a tiny bit of the truck experience by enabling air brake simulation in the options. When that's on if you apply them often enough to empty the can you'll need to wait for them to recharge. If you beat your truck up the brakes will begin to leak too, so you'll lose air when resting. (Gives more of an incentive to hit the shop reguarly.)

So, you guys mean it basically redices the engiene output, without you coming to a complete stop? If I'm getting this right?
