ASE A5 Practice Test exam with correct
answers

1. |On |a |car |with |disc/drum |brakes, |the |front |brakes |grab

quickly |when |light |pedal |pressure |is |applied. |This |problem

could |be |caused |by |a |bad:

A. |proportioning |valve

B. |pressure |safety |switch

C. |metering |valve

D. |residual |check |valve |- |✔✔C

2. |The |driver |of |a |vehicle |with |power |disc/drum |brakes

says |that |the |brake |pedal |moves |slowly |to |the |floor |while

maintaining |pedal |pressure |at |a |stoplight. |What |could

cause |this |problem?

A. |leaking |primary |piston |cup |in |master |cylinder

B. |leaking |power |brake |booster

C. |leaking |residual |check |valve |in |master |cylinder

D. |internal |leak |in |the |combination |valve |- |✔✔A

3. |Which |of |the |following |would |MOST |LIKELY |happen

if |the |measurements |taken |from |the |check |shown |above

varied |from |the |manufacturer's |specifications?

A. |noisy |brake |operation

B. |brake |grab |or |pull

C. |pulsating |brake |pedal

D. |low |brake |pedal |- |✔✔C

4. |What |is |the |purpose |of |the |master |cylinder |residual

check |valve(s) |on |vehicles |equipped |with |drum |brakes?

,A. |allows |the |driver |to |pump |up |the |brakes

B. |prevents |air |from |entering |the |hydraulic |system

C. |prevents |wheel |lockup |by |reducing |the |hydraulic

pressure

D. |reduces |pedal |pulsation |by |controlling |hydraulic

pressure |- |✔✔B

5. |A |technician |has |just |overhauled |the |front |brakes |on |a

vehicle |with |front |disc |and |rear |drum |brakes. |However, |when

he |attaches |a |pressure |bleeder |(pressurized |to |about |25

psi) |to |the |master |cylinder, |he |cannot |get |any |fluid |to |come

out |of |the |disc |brake |caliper |bleeder |screws. |Which |of |the

following |is |MOST |LIKELY |the |cause?

A. |bad |proportioning |valve

B. |bad |pressure |differential |valve

C. |proportioning |valve |release |button |not |activated

D. |metering |valve |release |button |not |activated |- |✔✔D

6. |On |a |vehicle |with |single |piston |floating |caliper |front |disc

brakes, |the |brake |pads |on |the |left |side |of |the |vehicle |are

almost |completely |worn |while |the |right |side |is |almost |new.

Technician |A |says |that |too |much |rotor |runout |could |be

the |cause. |Technician |B |says |that |a |binding |caliper |piston

could |be |the |cause. |Who |is |right?

A. |Technician |A |only

B. |Technician |B |only

C. |Both |A |and |B

D. |Neither |A |or |B |- |✔✔B

7. |What |is |the |purpose |of |the |bar |that |is |being |removed

from |the |brake |assembly |shown |below?

A. |to |equalize |the |braking |force |between |the |shoes

, during |normal |braking

B. |to |center |the |shoes |after |each |brake |application

C. |to |force |the |shoes |into |the |drum |when |the |parking

brakes |are |applied

D. |to |reduce |the |distance |between |the |shoes |and |the

drum |- |✔✔C

8. |A |hydraulic |brake |line |is |leaking. |Which |of |the |following |is

the |correct |repair |procedure?

A. |Cut |out |the |bad |section |and |replace |with |new |steel

tubing |using |compression |fittings.

B. |Replace |the |leaking |line |with |double-flared, |seamless

copper |tubing.

C. |Cut |out |the |bad |section |and |replace |with |single-flared

steel |tubing |using |flare |nuts |and |unions.

D. |Replace |the |leaking |line |with |double-flared |steel

tubing. |- |✔✔D

9. |The |set-up |shown |above |is |used |to |check: |(dial |indicator |on |rotor |face)

A. |rotor |parallelism

B. |wheel |bearing |adjustment

C. |rotor |lateral |runout

D. |rotor |face |wear |- |✔✔C

10. |Which |of |the |following |problems |would |be |caused |by

using |a |residual |check |valve |in |a |disc |brake |master |cylinder?

A. |reduced |brake |pedal |travel

B. |reduced |brake |system |pressure

C. |increased |brake |pad |wear

D. |increased |rotor |runout |- |✔✔C

11. |A |customer |complains |that |their |vehicle |pulls |to |the

right |when |the |brakes |are |applied. |Technician |A |says
