Brakes submodule
Use brake parameters to define hydraulic distribution, master cylinder areas, caliper area, effective radius, and pad friction.
Brakes define the hydraulic and mechanical brake model selected by a vehicle. Use this submodule when brake balance, cylinder sizing, caliper sizing, or pad friction changes need to be isolated from the rest of the vehicle.
When to use it
Use brakes when you need a reusable setup building block that can be selected in a vehicle assembly. Create and maintain it from Design > Brakes, then select it in the vehicle slot Brakes.
How it fits vehicle setup
- Create or duplicate the submodule from the Design section.
- Open the submodule row to review and edit parameter values.
- Save changes with Update Data.
- Open Vehicles and select the submodule in Vehicle Assembly.
- Use the vehicle detail tabs to inspect the selected submodule inside the vehicle context.
You need module create permission to create a new submodule and module update permission to edit values.
Parameter reference
Units, defaults, and ranges show n/a when no stable user-facing value was verified in the source used for this page. Method rows control which constant, lookup table, or polynomial rows are active in the product table.
Mechanical
| Parameter | Description | Units | Default | Validation / Range |

| Brake Distribution | The ratio of the hydraulic pressure in the front brake circuit in relation to the total pressure according to the following definition; brakeDistribution = brakePressureFront / (brakePressureFront + brakePressureRear) | % | n/a | n/a |
| Master Cylinder Area Front | The cross sectional area of the master cylinder for the front brake hydraulic circuit. | mm² | n/a | n/a |
| Master Cylinder Area Rear | The cross sectional area of the master cylinder for the rear brake hydraulic circuit. | mm² | n/a | n/a |
| Brake Pedal Motion Ratio | The mechanical motion ratio of the brake pedal between the application point of the foot against the pedal plate and the point for the push/pull rod for the master cylinders. | n/a | n/a | n/a |
| Caliper Piston Area | The total cross sectional area of all the pressure pistons in the brake caliper. | mm² | n/a | n/a |
| Brake Efficient Radius | The brake efficient radius of the brake caliper. | mm | n/a | n/a |
