ASE Brakes A5 Test ( Exam 2 ) with correct
answers
The |brakes |are |dragging |on |a |vehicle. |this |could |be |cause |by
a. |overfilled |master |cylinder |reservoir |
b. |low |vacuum |to |the |boost
c. |bypassing |master |cylinder |
d. |quick |take-up |valve |stuck |open |- |✔✔A |: |overfilled |master |cylinder |reservoir
why |: |an |overfilled |master |cylinder |reservoir |cylinder |would |not |allow |for |fluid |expansion. |this |would |
cause |the |brakes |to |self |apply |as |the |fluid |expanded |as |result |in |brake |drag
The |brake |pads |are |worn |at |an |angle |on |a |vehicle |with |a |sliding |brake |caliper |system. |which |of |the |
following |is |most |likely |the |cause?
a. |worn |caliper |piston
b. |worn |caliper |bushings
c. |leaking |caliper |seal
d. |leaking |caliper |boot |- |✔✔B |: |worn |caliper |bushings
why |: |worn |bushings |can |cause |the |caliper |to |cock |during |operation. |this |could |cause |the |pads |to |
wear |at |an |angle
A |diagnostic |trouble |code |is |set |for |an |open |wheel |speed |sensor |on |the |left |front |sensor. |The |
technician |measures |the |resistance |at |the |sensor |and |finds |it |to |be |within |specification. |Which |of |the |
following |is |the |most |likely |cause |for |the |wheel |speed |sensor |code?
a. |faulty |ABS |computer
b. |open |fuse
c. |open |wiring |from |the |computer |to |the |wheel |speed |sensor
, d. |shorted |left |front |ABS |modulator |valve |- |✔✔C |: |open |wiring |from |the |computer |to |the |wheel |
speed |sensor
why |: |an |open |in |the |wiring |from |the |sensor |to |the |computer |would |cause |a |diagnostic |trouble |code |
to |be |set |and |the |sensor |to |have |the |correct |resistance
The |brake |warning |lamp |pictured |above |(pg. |56) |stays |on |any |time |the |ignition |switch |is |on. |Tech |A |
says |this |could |be |caused |by |a |poor |ground |at |the |parking |brake |switch. |Tech |B |says |this |could |be |
caused |by |a |poor |ground |at |the |brake |warning |lamp |switch. |Who |is |correct?
a. |A |only
b. |B |only
c. |A |& |B
d. |neither |A |or |B |- |✔✔D |: |neither |A |or |B
why |: |neither |technician |is |correct. |there |is |a |ground |present |at |all |times |to |cause |the |light |to |be |on |
all |the |time
Which |of |the |following |is |true |concerning |the |above |caliper? |( |pg. |57 |)
a. |this |caliper |incorporates |the |parking |brake
b. |this |caliper |can |only |be |used |on |the |front
c. |this |caliper |can |only |be |used |with |Type |5 |brake |fluid
d. |this |caliper |must |be |replaced |at |each |brake |pad |replacement |- |✔✔A |: |this |caliper |incorporates |the |
parking |brake
why |: |^^^
Tech |A |says |a |double |flare |line |should |be |replaced |with |an |ISO |flare |line. |Tech |B |says |an |ISO |flare |line
|should |be |replaced |with |a |double |flare |line. |Who |is |correct?
a. |A |only
b. |B |only
c. |A |& |B
