 Systematic Approach to Air Brake System Operation and Troubleshooting

Details

This webinar was held on Monday, April 9, 2018


Overview

 
Bus pneumatic system operation and troubleshooting can be challenging to even the most experienced mechanics. Systematic Approach to Air Brake System Operation and Troubleshooting webinar is the first of four webinars designed to familiarize transit and suburban bus mechanics with the operation and basic troubleshooting techniques necessary to maintain modern bus pneumatic systems. Three additional webinars will follow this first installment. Supply, Control, and Foundation Brake System webinars will follow. Direct maintenance costs are significantly reduced, as the time required for servicing and repair reduces the out of service time, and increases the productive deployment of the vehicle while building mechanic confidence. 

This webinar will feature an overview of the complete pneumatic system including theory, operation, and troubleshooting tips. The webinar will present the following: 

  • General Information 
  • System Operation Overview 
  • Inspection Points 
  • Supply System
  • Control System
  • Foundation Brake System
  • Schematics 
  • Fittings and Tubing Identification 
  • Troubleshooting 

​It is necessary to check components regularly for their general condition. Using the information in this webinar, a transit bus maintenance team can tailor their air system inspections and maintenance, based on their operating profile, to ensure a long life and trouble-free operation of the pneumatic system.
