A |vehicle |with |ABS |anti-lock |brakes |has |an |audible |clicking |noise |when |it |is |first |started. |The |noise |
goes |away |after |a |few |seconds. |Technician |A |says |this |is |one |of |the |hydraulic |valves |in |the |hydraulic |
valve |assembly |sticking. |Technician |B |says |this |is |a |normal |condition. |Who |is |correct? |- |✔✔TECH |B |is |
correct. |The |ABS |system |runs |a |system |check |when |the |key |is |first |turned |to |the |ON |position. |The |
valves |sometimes |make |a |clicking |noise |during |this |check.
A |hydro-boost |brake |system |has |reduced |braking |performance. |Technician |A |says |to |check |the |power |
steering |system. |Technician |B |says |to |check |the |vacuum |check |valve. |Who |is |correct? |- |✔✔TECH |A |is |
correct. |The |power |steering |pump |produces |pressure |for |the |Hydro-Boost |unit.
A |vehicle |with |power |assisted |brakes |has |a |hard |brake |pedal. |Which |of |the |following |is |LEAST |likely |
to |cause |this |condition?
| A. |Master |cylinder.
| B. |Vacuum |check |valve.
| C. |Brake |booster.
|D. |Low |manifold |vacuum. |- |✔✔Answer |A |is |correct. |Faulty |master |cylinders |do |not |typically |result |in |
a |hard |brake |pedal. |Actually |it's |more |common |for |a |faulty |master |cylinder |to |cause |a |low |brake |
pedal |that |fades |to |the |floor |as |it |is |applied. |This |is |the |least |likely |component |listed |to |result |in |a |
hard |brake |pedal.
A |vehicle |pulls |to |the |left |only |when |the |brakes |are |applied. |This |condition |is |MOST |likely |caused |by:
| A. |A |seized |left |front |caliper.
| B. |A |restriction |in |the |left |front |brake |line.
| C. |Leaking |master |cylinder |cup |seals.
|D. |A |seized |right |front |caliper. |- |✔✔Answer |D |is |correct. |A |frozen |right |front |caliper |will |cause |the |
vehicle |to |pull |to |the |left |when |braking.
, Technician |A |says |accumulators |are |found |only |on |non-integral |ABS |systems. |Technician |B |says |some |
integral |ABS |units |contain |high |pressure |accumulators |that |must |be |discharged |before |repair. |Who |is |
correct? |- |✔✔TECH |B |is |correct. |High |pressure |units |can |be |dangerous |and |must |be |discharged |
before |removal. |Always |check |with |manufacturer's |procedures |before |disassembling |an |ABS |unit
Technician |A |says |ABS |control |units |are |programmed |to |ignore |speed |sensor |input |variations |below |a |
certain |threshold. |Technician |B |says |a |one-channel |ABS |system |controls |hydraulic |pressure |to |the |rear
|brake |units. |Who |is |correct? |- |✔✔Both |technicians |are |correct.
A |vehicle's |right |front |wheel |has |a |growl |that |increases |with |vehicle |speed. |The |MOST |likely |cause |is:
| A. |Excessive |rotor |lateral |run |out.
| B. |Warped |rear |brake |drums.
| C. |Worn |CV-Joint.
|D. |Worn |wheel |bearing. |- |✔✔Answer |D |is |correct. |A |worn |wheel |bearing |will |cause |a |growl |that |
increases |with |vehicle |speed.
Two |technicians |are |discussing |master |cylinder |residual |check |valves. |Technician |A |says |the |check |
valve |is |used |on |four |wheel |disc |brake |systems. |Technician |B |says |the |valve |maintains |pressure |when |
the |brakes |are |released. |Who |is |correct? |- |✔✔Technician |B |is |correct. |The |constant |low |pressure, |
usually |6 |psi |to |8 |psi |keeps |air |from |entering |the |wheel |cylinders.
The |brake |pad |wear |indicator |light |is |illuminated |on |the |instrument |panel. |Technician |A |says |this |is |
because |the |brake |pads |have |become |contaminated. |Technician |B |says |this |is |the |pad |wear |sensor |
contacting |the |brake |rotor. |Who |is |correct? |- |✔✔TECH |B |is |correct. |When |the |sensors |tip |contacts |
the |rotor, |the |pad |warning |light |illuminates |on |the |instrument |panel.
The |rear |wheels |of |a |vehicle |are |locking |up |only |when |the |brakes |are |applied. |This |is |caused |by |a |
faulty:
A. |Metering |valve.
| B. |Pressure |differential |switch.
| C. |Proportioning |valve.
| D. |Brake |switch. |- |✔✔Answer |C |is |correct. |The |proportioning |valve |prevents |rear |wheel |lockup.
Which |of |the |following |brake |fluids |are |silicone |based.
| A. |Dot |2
| B. |Dot |3
| C. |Dot |4
| D. |Dot |5 |- |✔✔Answer |D |is |correct. |Dot |5 |brake |fluid |is |silicon |based.
A |vehicle |stops |but |the |brake |pedal |fades |completely |to |the |floorboard |afterwards. |There |are |no |
external |leaks. |Which |of |these |is |the |MOST |likely |cause |of |this |condition.
