ICBC Air Brake Exam Questions With
Correct Answers
how |is |heat |dissipated |that |is |generated |by |the |brakes
Absorbed |by |the |brake |drums |and |dissipated |by |the |atmosphere
If |one |of |the |brake |shoes |are |poorly |adjusted |what |effect |could |it |have |on |the |remaining |sets |
of |brake |shoes |in |the |system
they |would |increase |their |share |of |the |braking |possibly |causing |overheating
If |40psi |is |exerted |against |a |diaphragm |of |30 |square |inches |in |area, |what |is |the |total |force |that
|could |exerted
1200lbs
Maximum |reservoir |pressure |must |be |between |what |two |pressures?
105 |Psi |and |135 |Psi
By |what |pressure |should |the |governor |cause |the |compressor |o |return |to |its |loading |stage
80-85Psi
how |often |should |the |reservoirs |be |drained?
, daily |or |more |often |under |extreme |condition
what |must |the |driver |do |when |a |low |pressure |warning |system |activates
stop |the |vehicle |and |find |the |cause |of |the |air |pressure |drop
if |the |weight |of |a |vehicle |is |doubled, |how |many |times |must |the |stopping |power |be |increased |
to |stop |to |the |same |distance
two |times
Signs |posted |in |advance |to |a |downgrade, |instructing |truck |drivers |to |stop |and |check |brakes |
are?
Regulatory |signs
what |causes |moisture |to |form |in |the |air |system
compressed |air |becomes |hot |then |cools |creating |condensation
how |are |most |compressors |lubricated |today
From |the |engine |lubricating |system
when |air |pressure |int |eh |reservoir |is |at |its |maximum |the |compressor |is
unloaded
