Realistic braking for trucks and tractors. A companion to Realistic Diesel Start (GN Realism), but it works perfectly on its own.
Features
- Real parking brake: its holding force depends on the vehicle’s weight, trailers included, and the slope. Leave a loaded truck on a steep downhill with more weight than the brake can hold and it rolls away, just like in real life. When released, the vehicle rolls on a slope even with you inside.
- Hill start aid: stop on an uphill with the parking brake released and the brakes stay applied for up to 3 seconds or until you accelerate.
- Dynamic engine brake: engine braking depends on the gear. In a high gear the vehicle keeps rolling when you lift off, while shifting down makes the engine hold it back.
- Exhaust brake, also known as Jake Brake: automatic when you release the throttle, or manual with the B key. It only works with the engine running, no throttle and enough rpm. Its light turns green only while it is actually braking.
- Brake fade: brakes heat up at their own rate for each vehicle type. A car cools quickly, a tractor with oil-immersed brakes is hard to overheat, and a loaded truck on a long descent can fade in a few minutes. If they stay too hot for too long, the linings are damaged until you visit the workshop. If they start to heat up, a message tells you to use the engine brake or shift down.
- Trailer air hoses: a trailer with air brakes stays braked while its hoses are disconnected, like a real truck. With FS25_manualAttach or Interactive Control, connect the hoses manually. With automatic attaching, they connect by themselves.
- Sounds: exhaust brake, brake squeal when the brakes are too hot, the truck’s air parking valve or the tractor’s lever ratchet, and the air exhaust when releasing the brake pedal.
- Discreet HUD: small lights next to the speedometer, the same size as Advanced Damage System’s, for the parking brake, engine brake, brake temperature, with a small number on trucks, and a brake failure light that only appears when there is damage. There is one layout with ADS and another without it. The indicators are never drawn over menus.
- Multiplayer and Dedicated Server supported.
- Translated into Spanish, English, German and French.

Changelog
- V1.4.0.1
Multiplayer settings: the mod’s settings now belong to the savegame. They are saved with it, the host, or an admin on a dedicated server, chooses them in Game Settings, and they apply to every player, including those who join later. Before, each PC used its own settings: other players could not see them, and what the host changed did not reach them. Existing savegames start with the settings the host already had.
Hill start aid: the “apply the parking brake” warning only appears when the vehicle actually starts rolling. Before, it always appeared when the aid released, even if soft ground kept the wheels chocked and the vehicle did not move.
Cruise control and shuttle: with cruise control on, changing direction with the shuttle left the tractor unable to drive off again because the mod took cruise control as a released throttle and opened the clutch. Cruise control now counts as throttle. Thanks Rems 834 for the report.
Compatible with savegames from 1.4.0.0 and 1.3.0.0. Multiplayer and Dedicated Server supported. - V1.4.0.0
Update over the published 1.3.0.0. Includes 1.3.0.1 and 1.3.1.0, which were never uploaded.
New, hill start aid: when you stop on an uphill with the parking brake released, the brakes stay applied for up to 3 seconds or until you accelerate. After that it rolls. To keep it still, use the parking brake.
With the parking brake released, the vehicle now rolls on a slope even with you inside, and a parked truck without its parking brake rolls away. An engine brake does not hold a stopped vehicle.
Engine brake advice: if the brakes heat up on a descent, a message tells you to use the engine brake or shift down before they start to fade.
On trucks, the brake temperature appears as a small number under its warning light, so you can watch it rise.
New, smaller brake failure light: it only appears once the linings start to get damaged, in amber, next to the temperature light.
Fixed, dedicated server: the parking brake and the engine brake did nothing because the server did not see who was driving.
With Advanced Damage System, burnt brake linings could never be repaired at the workshop. Brake condition is now handled by ADS, and this mod only simulates the heat.
The AI helper no longer jerks on slopes when you left the parking brake released.
Warning lights no longer draw over menus and dialogs, such as Real Fuel Consumption’s report.
Compatibility, Continue Driving After Exit: the vehicle no longer brakes by itself while that mod keeps driving it.
Compatibility, CVT Addon: on tractors with its transmission, the wheels no longer lock when you release the accelerator.
Compatibility, AutoDrive: if you are seated while AutoDrive drives, the mod no longer releases its brake at stops.
Settings: the mod’s parking brake, the hill start aid and the engine brake advice can be turned off. Fewer options: “Engine brake level” stays at 2, and “Trailer air hoses” is always on, so these options are gone. Warning lights are the same size as Advanced Damage System’s, with one position when ADS is installed and another when it is not.
Sounds for trucks: air exhaust when releasing the brake pedal, louder the harder you braked. Releasing the parking brake has its own sound, and applying it is louder. The engine brake is quieter, especially inside the cab.
Compatible with savegames from 1.3.0.0: no new game is required. Multiplayer and Dedicated Server supported. - V1.3.0.0
New, trailer air brake hoses: a trailer equipped with air brakes remains braked while its air hoses are disconnected, just like a real truck. Without a supply of air, its spring brakes automatically apply.
Works with FS25_manualAttach and Interactive Control: first connect the trailer, then connect the air hoses, and only then will the trailer be able to move. Disconnecting the hose produces an air-release sound.
With the game’s automatic coupling system, the hoses connect automatically, so nothing changes.
With Realistic Engine Start, the trailer has its own air tank and fills from the truck’s air supply. The truck’s air pressure drops, an empty trailer uses almost half of the available air, and the compressor takes longer because it has to fill both tanks. The trailer disconnects at 4.1 bar.
When the trailer’s brakes are applied, the wheels lock up, just like a real truck with the spring brakes engaged. The truck can barely pull it, slowly and under heavy load.
The truck never loses its own brakes because of this. Trailers without air brakes, trailers pulled by tractors without air connections, and trailers operated by a Worker behave as usual.
If you try to drive with the trailer’s brakes locked, a message explains why.
This feature can be disabled in the settings.
New, parking brake sound: trucks play the sound of the air parking-brake valve; tractors and other vehicles play the mechanical ratchet sound of the lever.
Engine brake indicator: the indicator remains dim or off while the engine brake is not actually braking, including when automatic mode is armed. It only turns green when the engine brake is actively retarding the vehicle. Previously, it remained illuminated all the time.
HUD indicators: with a HUD scale other than 1, the indicators could become misaligned from the speedometer. They now remain correctly positioned alongside the gauge at any HUD scale. A vehicle excluded from Advanced Damage System now uses the correct indicator layout without ADS.
Compatible with savegames from 1.2.0.0: no new game is required. Multiplayer and Dedicated Server supported.
