Realistic braking system for trucks and tractors, designed to add an extra layer of simulation to your game. It works on its own and is also a companion to Realistic Diesel Start (GN Realism).
Features
- Real Handbrake
The braking force depends on the vehicle’s weight, including trailers, and the slope of the terrain. A loaded truck left on a downhill slope with too much weight for the brake to handle can roll away on its own. The usual solution is to chock it or leave it running. - Dynamic Engine Brake
Engine braking depends on the gear. In a higher gear, releasing the accelerator allows the vehicle to keep rolling. Downshifting makes the engine pull in reverse for real, like engine braking in a real truck. - Reinforced Engine Brake, Jake Brake type
It activates automatically when the accelerator is released, like a modern retarder, or manually with theBkey. The mode can be selected from the game’s Settings menu. It has 3 intensity levels and only works with the engine running, not accelerating, and at sufficient RPM. - Brake Fade
Brakes heat up at different rates depending on the vehicle type. A car with ventilated discs cools down quickly, a tractor with oil-immersed brakes is difficult to overheat, and a loaded truck on a long downhill can reach critical brake fade in just a few minutes if engine braking is not used. Keeping the brakes very hot for too long permanently damages them, requiring a trip to the garage. - Sound
Engine braking has its own distinct sound, the classic “swish-swish” of the exhaust during engine braking. When the brakes enter the alert zone at 200°C, the brake pads squeal when the pedal is pressed. - Discreet HUD
Displays brake temperature, efficiency, and parking brake status, with alerts when entering the alert zone or risking damage. - Game Settings
Engine braking mode, automatic or manual, engine braking level, thermal fatigue intensity, and HUD visibility are configurable from the game settings. No console or game file changes are required. - Translated into Spanish, English, German, and French.
Compatibility
It works seamlessly with Enhanced Vehicle. If it is installed, the handbrake is controlled by this mod, eliminating conflicts over vehicle control.
If Realistic Diesel Start (GN Realism) is installed, the air brakes of its compressed air system are automatically integrated with the parking brake.
Multiplayer compatible.
Notes
Mod under active development. Bugs and suggestions can be reported in the comments.
V1.3.0.0
- TRAILER AIR BRAKE HOSES, new
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, as 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.
- PARKING BRAKE SOUND, new
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.
V1.2.0.0
- Fixed an issue where the engine brake did not work on any truck in some cases.
- Fixed an issue where the handbrake did not work on certain occasions.
- New dashboard warning lights, brighter and faintly visible when switched off.
- The brake temperature and malfunction warning only appear on trucks.
- Compatibility with Advanced Damage System. The icons are repositioned when the mod is active to prevent them from overlapping.
V1.1.0.0
- Bug fixes: The AI no longer freezes or pauses while working in the field, including with a cultivator or seeder, or hauling on the road.
- Background redesign: AI-driven vehicles are now completely excluded from the brake simulation, including temperature, wear, and parking brake. Only the player experiences the full physics.
- Fixed: A vehicle parked on a slope with the parking brake engaged no longer rolls on its own when loading a saved game.
- Fixed: The engine brake no longer remains active on the HUD or interferes while the AI is driving.
- Engine brake sound issues resolved.
- Handbrake is now actually saved in the game. Before, it always returned to “engaged”.
- Enhanced Vehicle compatibility.
- Sound volume reduced, as it was very intrusive, and converted to OGG, with a 73% smaller file size and no performance warnings.
- Clean cutoff when disengaging the engine brake. Previously, it would continue playing in the background.
- The sound now correctly releases when deleting a vehicle. Previously, it would accumulate in memory.
- Updated HUD: New icons for parking brake, engine brake, temperature, and malfunction, replacing the text.
- Earlier temperature warnings, aligned with the actual physics of brake failure.
- Brake failure is now indicated with the (!) icon.
- Position and size of each icon adjusted.
