    Vehicle Inspector (RBM1-1)

    Quick Facts
    Course ID: RBM1-1
    Duration: 1 Day

    Detailed description of the AECS COF-B Roller Brake Tester Inspection training.

    This NZTA Authorised training is aimed at Vehicle inspectors (CoF and WoF). The training is specifically designed for CoF B (heavy goods vehicles) vehicle inspectors, but is very useful for Cof-A and WoF inspectors. The content deals with brake and stability engineering principles in a manner that makes even the most experienced operator of any brand roller brake tester, look at the results produced by their equipment, in a very much more professional manner.
    This training is also recognised as part of the Mito Vehicle Inspector CoF B education.

    The Course is applicable for any brand brake tester.

    We cover the following subjects:

    • Understanding the principles of a roller brake tester. What is actually measured on a RBM when lock up occurs and when no lock up occurs.
    • What factors affect the RBM test results that are displayed.

      training manual pictures.

    • What is grip, engineering principles explained in simple terms.
    • What is the effect of weight and grip on the brakeforce measured and how does this affect the calculated brake efficiency.

    • Learn how to predict brake force and efficiency, so you recognise a vehicle or RBM fault in an instant.
    • How does brake efficiency relate back to legal minimum deceleration rates.

    • What needs to happen with the brake force, when lock up occurs on the road to regain grip again (ABS/EBS/ESP).
    • Which factors (e.g. roller surface, rubber compound tires, etc.) affect grip on the road and on the RBM.

    • How does the RBM measure brake force.
    • What is the sense of measuring dynamic weight during a brake test, and how is it measured.
    • What is the effect of brake imbalance on RBM results and vehicle direction on the road.

      training manual pictures.

    • Which factors affect brake imbalance (e.g. unequal tires, tire pressure, simulated loading, etc.).
    • The ins and outs of brake efficiency, legal terms and engineering principles.
    • RBM Approvals and RBM calibration, what does it mean for the inspector.
    • How to operate an RBM correctly step by step.
    • Hydraulic lift and pull down, limits, principles and pitfalls.

    • Brake test results interpretation.
    • Identification of different HD brake systems.
    • Common faults in brake systems.

    The course will be theory and practical (actual testing of vehicles).
    The practical part will be done at a pace to enable you to digest all of what is happening, with the theory in mind. Something that work pressures usually do not allow in the workshop.
    However, when the experience gained during this seminar has settled, the results read from the equipment in the workshop at workshop pace will be understood far better

    I finally properly understand what all the numbers mean on the test report, and that after all those years!

    The Vehicle Inspector can use his/her own brake tester, or a Brake Tester in our training centre (e.g. AECS STT45) can be used.
