78 Maintenance and Service
Brake System
DO NOT use replacement parts anywhere in the brake system unless it
conforms exactly to original specifications. A nonconforming part in your
vehicle's brake system could cause a malfunction, leading to loss of control
of the vehicle resulting in severe personal injury or death.
DO NOT release the parking brake or attempt to move the vehicle until
brake air pressure in both circuits is at least 690 kPa (100 psi). Failure to
follow this procedure may lead to uncontrolled vehicle movement and cause
severe personal injury or death.
Automatic slack adjusters MUST NOT be manually adjusted in an effort to
correct excessive push rod stroke, as this condition indicates that a problem
exists with the automatic adjuster, installation of the automatic slack
adjuster or problems related to components of the foundation brakes. These
conditions will not be corrected by manually adjusting the automatic slack
adjusters.
Manual adjustment of automatic slack adjusters is a dangerous practice
that could result in serious consequences. This practice gives the vehicle
operator a false sense of security about the effectiveness of the brakes, and
the brakes will likely soon be out of adjustment again.
The brake system is a critical vehicle safety system. For your safety and for
those around you, follow the recommended preventive maintenance checks. If
any problems occur, have them investigated immediately by an authorized
service facility.
