Evaluation of Brake System Performance for Transit Bus Operation and Maintenance 2001-01-2747

Improper brake system performance and braking force distribution on transit buses causes vehicle instability during braking directly affecting it's handling and safety. It also affects vehicle maintenance cost due to premature brake component and tire wear.

The purpose of this paper is to discuss the transit industry's experience regarding brake testing, that would help to evaluate system performance, using the most efficient and inexpensive method (depending on the required task) available at this time. A successful discussion within the SAE may suggest a guideline to agencies responsible for vehicle safety (e.g., DOT) to review and then establish requirements for bus brake system design and evaluation technique and criteria. This will in turn positively effect transit industry operation and maintenance.
