INSPECTION GUIDELINE BRAKE SYSTEM
OPERATION & MAINTENANCE for EMERGENCY VEHICLES
The
following guideline contains suggested periodic inspections
as a means for verifying the operation and maintenance of
vehicle braking systems as defined in NFPA 1911 (Standard
for the Inspection, Maintenance, Testing, and Retirement of
In-Service Automotive Fire Apparatus, 2007 Edition, chapter
7.12 ), and can be conducted on any vehicle used in
connection with emergency response. This guideline has been
developed STRICTLY as an intermediate supplement and is not
intended to supersede any established department inspection
procedures already being performed during regular scheduled
preventative maintenance (P.M.) service.
All work should be performed by qualified Emergency Vehicle
Technicians as defined in NFPA 1071 (Standard for Emergency
Vehicle Technician Professional Qualifications, 2004
Edition), in conjunction with the Federal D.O.T. and vehicle
manufacturer’s recommendations. Although the AHJ (authority
having jurisdiction) can determine who is qualified,
essential certifications such as ASE, EVT and FAA should be
required as an absolute minimum. These certifications are
ongoing and require periodic re-certification.
Vehicle manufacturers have published overall maintenance
schedules in the vehicle owner’s manual. Brake and axle
manufacturers also have published guidelines on specific
intervals for inspecting brake and axle components. It is
usually required on an as-needed basis. However, some
departments perform these intermediate inspections as often
as four times a year depending on mileage. As a
precautionary measure, it is recommended that these
inspections be conducted at least bi-annually between
regular scheduled P.M. service. These inspections usually
can be conducted in approximately two hours per truck and
should be accompanied by a written report on each truck as
to the findings.
Without removing the wheels, all inspections are visual in
nature and operational functions are demonstrated and
witnessed. Minor adjustments should be addressed as required
and any further corrective action must be noted in the
written report.
1.) REVIEW ALL OPERATIONAL PROCEDURES, POLICIES AND
DEPARTMENT SOP’S THAT PERTAIN TO DAILY, WEEKLY AND MONTHLY
