The Brake System:
Inspection Procedures For The Air-Hydraulic Brake System
Introduction
Maintenance of air-hydraulic brake systems is much the same as that for straight hydraulic brake systems. The major difference between the two is that the air-hydraulic system contains components for compressing air and applying air pressure to the hydraulic system.
As with any other automotive system, a well-organized sequence of events must take place to properly maintain air-hydraulic braking systems. The steps to take include a preroad test inspection, a road test, and an after-road test inspection to determine if there are any troubles, a troubleshooting step to determine the cause of any failure, and then the service and repair required to correct the failures.
The maintenance procedures between 2 1/2- and 5-ton military vehicle braking systems will not vary too much. Therefore, throughout this lesson, general maintenance practices will pertain to all air-hydraulic brake systems unless specific exceptions are discussed. |
