23.  AIR SYSTEM TROUBLESHOOTING 

The following list has been designed to help in 
troubleshooting some of the most common 
problems in the air system and main causes. 
For air brakes troubleshooting, refer to “

Air 

Brakes Troubleshooting” 

in this section. For 

more troubleshooting information, refer to the 
manufacturer's brochures annexed to this 
section. 

Air pressure doesn't rise to, or doesn't maintain, 
a normal setting: 

o

  Defective air gauge (registering incorrectly). 

o

  Excessive leaking in air system. 

o

  Reservoir drain cock open. 

o

  Governor poorly adjusted or defective. 

o

 Defective 

compressor. 

o

  Worn compressor or excessive wear on 

piston and/or ring. 

o

  Air pressure rises to normal setting too 

slowly. 

Excessive leaking in air system: 

o

  Clogged engine air cleaner. 

o

  Worn compressor or excessive wear on 

piston and/or ring. 

o

  Engine speed too low. 

Air pressure rises above a normal setting: 

o

  Defective air gauge (registering incorrectly). 

o

  Governor poorly adjusted or defective. 

o

  Restriction in line between governor and 

compressor unloading mechanism. 

Air pressure drops quickly when engine is 
stopped: 

o

  Leaks in compressor discharge valve. 

o

  Leaks in governor. 

o

  Leaks in air lines. 

o

  Leaks in air system valves. 

24. BRAKE OPERATION 

The vehicle braking system uses both service 
and parking air-operated brakes. The air system 
is divided into two independent circuits to isolate 
the front axle brakes and the rear axle brakes 
(drive and tag), thus providing safe brake 

operation in the event that one circuit of the 
system fails. The primary circuit is connected to 
the drive and tag axle brakes, while the 
secondary circuit is connected to the front axle 
brakes. The tag axle service brakes operate only 
when the axle is in the normal driving (loaded) 
position. The spring-type emergency brakes are 
mounted on the drive and tag axles, and will 
apply automatically if primary system pressure 
falls below 40 psi (276 kPa). 

Furthermore, brake application or release, which 
is speed up by a pneumatic relay valve (R-12), 
will start with the rear axles and be followed by 
the front axle, thus providing uniform braking on 
a slippery surface. The vehicle is also equipped 
with an Anti-lock Brake System (ABS), detailed 
later in this section. 

Brake and air system maintenance consists of 
periodic inspections. Check all parts for damage 
and brake adjustment (refer to subsequent 
headings in this section for more details). Ensure 
all fasteners are tight (refer to “

Specifications"

 for 

recommended tightening torques). 

25. AIR BRAKES 

25.1 DISC 

BRAKES 

Knorr-Bremse SN7000

 disc brakes are used on 

all axles. The front and drive axle discs are 
actuated by 24 square inch effective area air 
brake chambers, while on tag axle, the brake 
chambers have a 16 square inch effective area 
for service brake and a 16 square inch effective 
area for emergency/parking brakes. The 

Knorr-

Bremse SN7000

 brakes are supplied with 

automatic clearance (slack) adjusters as 
standard equipment for easier adjustment. For 
more information on disc brake components and 
maintenance, refer to the manufacturer's 
brochure at the end of this section. 

25.1.1  Disc Brake Pads 

Brake pads have to be checked on a regular 
basis depending on the vehicle operation. The 
remaining thickness of the pads should never be 
less than 3/32 in (2 mm). To check pad 
condition without removing the wheel, verify the 
position of guide bushing (6) relatively to guide 
sleeve (4) (see Fig. 21). When guide sleeve is in 
alignment with guide bushing, brake pad 
thickness has to be checked more precisely with 
the wheel removed. When replacing brake pads, 
all four pads on an axle have to be changed at 
the same time. There is no inner or outer pad,
