Brake Management Introduction

Manage brake sets in HH Data Management using assemblies and the item measurements view. This article explains how to define brake assemblies and record measurements.

Assembly definition

Define the assembly structure based on the specific brake management requirements of the vehicle. Use the table below to determine the necessary assembly configuration:

Management requirement	Assembly configuration
Build sheet selection	Define if front and rear sets are selected simultaneously or independently. This determines if one assembly covers both axles or if separate assemblies are required per axle.
Disc and pad pairing	Determine if discs and pads are always paired by axle or side. Create part items for individual components or a single item for the pair accordingly.
Disc replacement	Identify if discs are changed as a pair or individually to determine if one or two selections are required.
Pad replacement	Determine if pads are changed by corner or axle to set the number of selection points in the assembly.
Corner specificity	Determine if discs are corner-specific (e.g., a left disc cannot be used on the right). Create separate part categories for each corner (e.g., "FrontLeftDisc") if parts are unique. Use a general category (e.g., "FrontDiscs") if parts are interchangeable across the axle.

Example configuration : Front axle

This example demonstrates a front brake set assembly where discs and pads are defined per corners (1 disc and 2 pads per corners). In this setup, discs and pads are interchangeable between the left and right sides.

Part categories

Create one part category for :

• Front discs
• Front pads

Add parts (can be one part per specifications) and part items.

Brake set assembly

Create a FrontBrakeSet assembly

Add part parameters to the assembly iteration definition

Add assembly parameter to the Setup definition

Create a front brake set named assembly in the named assembly inventory

tip

Maintain a consistent brake set name while creating multiple iterations for disc or pad changes by defining several named assemblies.

Create the iterations in the assembly iteration inventory

Add an assembly iteration selector in the BuildSheet/SetupSheet CID

tip

If several named assemblies are used, a named assembly selector can be added in addition to the assembly iteration selector. The last iteration will be automatically selected when the named assembly is selected. The assembly iteration selector can be filtered depending on named assembly selected.

Part items selected in the assembly iteration can be displayed with a flat model textbox using the expression binding path option.

Measurements

Use the item measurement view to define the brake set measurements.

Create the measurement parameters in each part item measurement definitions.

Create a CID named "MeasurementView" in the assembly iteration measurement definition.

Link measurement point textboxes to the part item measurements to ensure data saves to the part item. This prevents data from saving to the assembly in cases where a part item is reused in another assembly. Use a flat model textbox to access the measurement.

Wear can be calculated in the part item measurement definition by comparing with the previous value or with the new value

The InitialWearValue is created in the part definition.

Average wear of both discs or 4 pads can be calculated in the assembly iteration measurement definition

Everything can be displayed in the CID with math parameter display or flat model textboxes

Event Name and Car Number can be automatically filled when creating a measurement with a flat model textbox with the following paths

• Event: Event.Name
• Car: Car.Number

A manual Session selection can be added with a basic combobox :

• Items Source Binding Path: Event.Sessions
• Selected Value Binding Path: SelectedSessionId (Note: Add this text parameter to the assembly iteration measurement definition)
• Display Member Path Name
• Value Member Path: Id

Customize the assembly iteration view

The assembly iteration view can be customized by creating a custom column profile linked to the assembly iteration definition. This example shows how to add a column with the last measurement value to be able to filter/order the brake sets depending on this value

Create a new profile linked to the assembly iteration definition

Use the Create Default Columns button

Create a new text column
