Overview

Disc brakes have been used on transit buses for over fifteen years but misconceptions remain regarding their operation and maintenance. Disc brake technology brings immediate cost savings for transit/coach operators thanks to reduced weight, compact design and easier servicing compared with drum brake systems. Disc brakes can be found in different configurations; disc in combination with drum brakes, or disc brakes on all axles. Disc brakes are a good fit with hybrid and electric vehicle technology. 
There are two basic forms of disc brake periodic maintenance inspections. The Wheels On inspection is a basic periodic check that was covered in a previous webinar. Today’s webinar will cover a more in-depth inspection of the disc brake system and is performed with the wheels off.
The following areas will be covered in today’s webinar: 
Nomenclature
Caliper Identification
Pre-Inspection
Caliper Inspection and Tests
Brake Pad Inspection
Wear Indicators
Rotor Inspection
Brake Chamber Inspection
Brake Pad Installation
Testing and Validation
It is necessary to check some of the components regularly for their general condition. The inspection process, when followed, will ensure a long-life and trouble-free operation of the disc brake system. Periodic inspection intervals will vary based on environmental and operating conditions
