Note
This report is supported for fleets operating in the EMEA region (including UK & Ireland).
The Braking Performance Report (Maintenance > Brake Monitoring) provides a consolidated view of trailer brake health across your fleet. The Electronic Brake Performance Monitoring System (EBPMS) continuously tracks trailer brake performance based on real-world driving conditions. By analyzing live braking events, it helps you identify issues early and confirm whether a trailer is safe to stay in service.
To view braking performance data for your trailers, you must first install the AG53 and then connect the AG to the trailers EBS using the compatible cable. For supported vendors, see Electronic Braking System Vendors and Cable Compatibility.
The report displays data from the trailer’s electronic braking system (EBS) to assess braking performance, helping you stay ahead of potential maintenance issues and stay in compliance with maintenance requirements.
The braking report shows a summary for trailers in your fleet. Use the filters at the top of the report to filter trailer braking data by date, Tags, Attributes, or Braking Result. You can also use the Search to filter the report by specific trailer names.

Braking Result |
Shows the trailer’s current braking performance score: For the No Data score, only trailers with EBS cables will initially show up in this category. Trailers with other cables will not show up. For the Gathering Data score, this is assigned when at least one braking event has been detected. The trailer will stay in this category until sufficient data is collected. The exact number of brake events required is variable and depends on operating conditions of the trailer. It may take 200–300 qualified brake events or more to receive a pass or fail result. Each score also functions as a filter, letting you narrow the report to trailers with the selected braking performance status, while displaying the total count of trailers in that category. |

Name |
Name of the trailer for which braking performance data is available. |

Location |
Last reported location of the trailer. |

Braking Performance |
Calculated Brake Performance Value (BPV) for the last 90 days, projected at 6.5 bar pressure and full bogie load. A score of 45% or higher typically indicates a pass. The score updates every 6 hours. |

Braking score explanation |
The explanatory panel outlines how the Electronic Braking Performance Monitoring System (EBPMS) evaluates a trailer’s braking performance. |
|
Performance History Graph |
Visual trend of braking performance over time. The default view shows the last 90 days, but can be adjusted to align with inspection or maintenance periods. In general, a flat or slightly-downward trend in braking performance is expected over time. However, small variations in both directions are normal due to daily differences in operating and environmental conditions. Sharp increases in brake performance typically correspond to maintenance or corrective actions taken on the trailer. |
If needed you can also Download Report for the trailer’s braking performance, which can be reviewed by maintenance staff or attached to service records.
EBPMS works by comparing braking pressure (demand from the driver) to deceleration to determine the trailer’s braking performance. If the brake performance results in FAIL, the vehicle operator should take appropriate action according to local authority guidelines and regulations.
Typically, the trailer undergoes maintenance and a roller brake test (RBT) is performed to confirm roadworthiness. The RBT remains valid until the next scheduled periodic maintenance inspection (PMI).
Note
Since EBPMS and RBTs are different tests, it is not always appropriate to compare their results directly. EBPMS demonstrates performance under real-world conditions, making it more representative of in-service braking performance than a static RBT.
If a comparison is attempted, the RBT should be conducted laden with at least 65% of the maximum bogie load. Unladen tests only measure performance up to wheel lock, which is not comparable to real-world behavior.
Important
RBTs can exceed the 6.5 bar pressure used for EBPMS projection. Tractor units may deliver up to 8.5 bar, meaning poorly performing brakes could still pass an RBT at higher pressures. For the best comparison with EBPMS, ensure the RBT demand pressure is limited to 6.5 bar.
To notify a driver or receive a notification when the EBPMS performance has fallen below a chosen threshold for a specified duration, you can configure a Braking Score alert under Assets reading. For more information, see Alert Configuration
