Brake Colloquium & Exhibition 2020 Transitioning to Virtual Event

Due to concerns around the ongoing coronavirus (COVID-19) pandemic, SAE International has made the responsible decision to transition the Brake Colloquium & Exhibition to a virtual event and cancel the in-person event, originally scheduled for October 11-14, 2020, in San Antonio, Texas. Additional information for the virtual event will be made available in the coming weeks.

Before making this decision, we extensively monitored and evaluated health directives from governmental and international health authorities, government- and corporate-imposed travel restrictions, and distancing and gathering directives and recommendations. Our decision to transition to a virtual event aligns with our commitment to prioritizing the health and safety of our speakers, customers, partners and staff who attend our events, while continuing to share mobility knowledge in a digital platform. We apologize for any inconvenience this cancellation has caused.

Please see our Frequently Asked Questions for additional information.

Technical Program


The 2020 Brake Colloquium focuses on two critical trends impacting industry:  advancement of brake technology integrated with ADAS and other advanced safety features for today’s mobility, and the development on brake technology requirements for electric and automated mobility of tomorrow.

  • Consumer demand for improved NVH and performance
  • Braking for ADAS and autonomous vehicles

Plan now to attend Sunday Tutorials

Fundamentals of Tribology – A  Brake Engineering Perspective Tutorial

Sunday, October 11

Tribology in its most basic definition is the science of interacting surfaces in relative motion. For brake engineers, knowing how these surface interactions generate resistance to motion (friction) and alter the surface characteristics of each of the sliding bodies (wear) is critical. Understanding the surface interactions requires a multidisciplinary approach. A vast majority of the research is focused on eliminating friction and minimizing the wear of components. The brake industry is interested in controlling the friction level at some nominal level while minimizing the wear of the sliding components.

This tutorial will explore:

  1. Defining and characterizing surfaces
  2. Mechanisms of friction generation
  3. Mechanisms of wear
  4. Practical examples

Aerosol Measurements – Principles, Techniques and Application to Brake Emissions Tutorial

Sunday, October 11

The proper measurement and assessment of brake emissions is a challenge to traditional testing in many aspects. First, the analysis itself can involve over 100 data channels for a single brake. Besides, the orders of magnitude are much larger or significantly smaller, compared to legacy brake tests, from measuring distances in millimeters to measuring particles in nanometers (one-millionth of a millimeter). And, from counting items in hundreds (degrees of temperature or braking events) to counting particles in millions, or tens of millions for particles on a single particle size bin during a brake test.

This tutorial helps the audience navigate through brake emissions data, make sense of its meaning, and make better decisions for a vehicle, a system, or a component program. The tutorial (using examples and real time measurements) explains critical concepts related to particle mass (PM), particle number (PN), size distribution, and new particle formation process. The second part describes the measurement techniques and principles of PM, PN, Particle Size Distribution (agnostic to system supplier, integrator, and duty cycle). The final section of the tutorial provides insight into the standard and acceptable metrics to report particulate matter behavior and characteristics.
