Basic Air Systems

This seminar is first in the series review for Air Systems. It will go over just how your systems are supposed to work. Learn how to identify the problem the first time, and eliminate needless replacement of components.

This seminar will cover:

• When & where to use air de-icer
• Service versus replacement of air compressor
• How to clean the system after a failure
• Difference between an air dryer and an after cooler and the effect on the air system
• Basic functions of valves and how they relate to brake balance and wear
• Identify and troubleshoot the charging park and emergency system
• Maintenance of Air Systems

Air Brake Foundations 

The focus of the Air Foundation class is a common sense approach to performing a brake job.

This seminar will cover:

• How to disassemble the wheel
• How to take a complete analytical look at the components
• How to diagnose wear patterns and component failure to determine air system problems versus foundation problems
• How to identify acceptable tolerances and whether or not a component should be reused
• Proper wheel bearing inspection procedures with proper installation methods, proper wheel seal inspection,& installation procedures

Please contact Lisa Jo Steiner at 603-415-8310

* Each attendee will receive a brake adjuster’s certificate at the end of class *

 

Air Brakes ABS Systems 

This class (Anti-Lock Brake Systems) offers diagnostics and proper maintenance procedures on the Rockwell Wabco/Bendix systems.

Discussion topics for the ABS System seminar to include:

How do anti-lock brakes work?

The main advantage of anti-lock brakes is that they can reduce braking problems on wet and slippery roads. Anti-locks work with a vehicle’s normal service brakes to decrease stopping distance and increase the control and stability of the vehicle during hard braking. The principle behind anti-locks is that a skidding wheel provides less stopping force and control than a wheel that is rotating. Anti-locks prevent wheels from skidding by monitoring the speed of each wheel and automatically pulsing the brake pressure on any wheels where skidding is detected.

Where are anti-lock brakes required?

The standard for tractors requires anti-lock control on the front axle and at least one rear axle.  Each wheel must be independently controlled by an anti-lock modulator on at least one of the tractor axles.  This ensures that a wheel provides shorter stopping distances and optimal braking force on all surfaces, especially on roads where one side is slipperier than the other. For semi-trailers, at least one axle must have anti-locks. Full trailers must have anti-locks for at least one front and one rear axle.
