Brake Pad, Disc & Shoe Measurement

The inspection and maintenance of the brake systems is critical to the safety and efficiency of all rail operations.

MRX Technologies has a suite of measurement systems developed specifically for the condition monitoring of brake components.

The Brake Pad Monitoring System (BPMS) uses precision technology and tailored software to provide accurate and reliable wear measurements.

Roll-by measurements provide a set of 3D spatial curves and a precise profile of the brake pad, braking plate and wheel.

Brake pad thickness is calculated and sent to a controller (and can also be recorded for monitoring of components over time) for instant reference.

The BPMS is installed in a secure enclosure and can be used independently or as part of an integrated rail vehicle measurement system.

The BPMS in brief:

             A valuable tool for planning maintenance

             Can be used to trigger an alarm for damaged/missing pads

             Can be integrated with other VEMS modules

The Brake Disc Measurement System (BDMS) creates precise profile measurements of both wheel-mounted and axle-mounted brake discs (or both if required).

The non-contact system operates on a roll-by basis, providing images and precise measurements and the BDMS can trigger an alarm for any serious abnormalities with the brake disc.

Measurements provided by can be used in plotting the wear and usage of brake discs for effective maintenance planning by the operator.

The BDMS in brief:

             Measures wheel or axle-mounted brake discs

             Provides precise measurements

             Non-contact

MRX also has a system specifically designed for the accurate and regular measurements of brake blocks (or shoes) for each wagon wheel.

The Brake Shoe Monitoring System (BSMS) provides an immediate check of brake block wear condition against specified wear limits, creating a wear history which is used to anticipate available brake wear life.

By using roll-by images and measurements to identify abnormal wear rates (as well as damaged or incorrectly installed brake blocks) rail operators can prevent accidents and safety hazards from occurring.

Other benefits of this technology include:

             Reduced inspection costs

             Enhanced maintenance management information

             Extended component usage life
