The Rules for HVAIS require air brake systems (including air-over-hydraulic) fitted to heavy vehicles to be inspected as part of the safety check inspection. Appendix ‘O’ of the HVAIS rules and Vehicle inspectors bulletin (VIB) No. 14 Test procedures for air brake systems outline the procedures to be used for inspecting and testing air brake systems on heavy vehicles. Mercedes-Benz based trucks and buses fitted with an air-over-hydraulic brake system are designed with a dual circuit split system. In the event of a failure of one sub-system, braking is provided through the intact circuit. As a result of the spring brakes applying the integrity of the braking system as outlined in VIB No.14 Section 2, Part B Clause 8 may not be able to be determined. To determine the integrity of the braking system for the Mercedes-Benz air-over-hydraulic brake system the following procedure replaces VIB No. 14 Section 2, Part B Clause 8. Inspection procedure 1. Ensure the vehicle is located on stable and level ground. 2. Ensure the vehicle’s wheels are chocked. 3. Open the vehicle’s bonnet (the bonnet release is located in passenger side foot well). 4. Locate the test ports. There is one test port located on each of the pneumatic/hydraulic servos under the bonnet. The inboard test port is for the primary circuit (front brakes) and the outboard test port is for the secondary circuit (rear brakes). To help find the location of the test ports refer to Figure 1A. 5. Remove the rubber covers from the test ports to reveal the white release valves (see Figure 1B).
