ASE A5- BRAKES EXAM 2025
QUESTIONS AND ANSWERS
Front Brakes of a vehicle with front disc and rear drum brake system skid when brakes are
applied, what would cause this condition? - ANS Metering valve
A cars brake lights are completely inoperative. Tech A states the brake light switch is stuck
closed. Tech B states the circuit may have shorted and blown a fuse. Who's correct? -
ANS Tech B- circuit may have shorted and blown a fuse
Integral drum parking brake system is being discussed. Tech A says binding cable will prevent
parking brake application. Tech B states this system contains a brake strut. Who's right? -
ANS Both- binding cable will prevent parking brake application and Integral drum parking
brake system contains a brake strut
Regarding electric parking brake systems: Tech A states this requires manual adjustments. Tech
B states a special procedure is needed before replacing the brake pads. Who's right? -
ANS Tech B- a special procedure is required before replacing brake pads on an electric
parking brake system.
A technician is measuring the inside diameter of a brake drum with a brake drum micrometer.
The technician should use what kind of measurement? - ANS The largest measurement
Regarding brake backing plates: Tech A says if a ridge has formed on the pads where the shoes
rest they may be filed to restore a smooth finish. Tech B states to apply bearing grease to
reduce brake squeak. Who's right? - ANS Tech A- if a ridge has formed on the pads where the
shoes rest they may be filed to restore a smooth finish.

,The Brake Pedal feels softer after the master cylinder being replaced. Tech A states its a leaking
power booster. Tech B says air in the hydraulic system. Who's right? - ANS Tech B- air in the
hydraulic system.
A car's brake pedal goes all the way to the floor. Tech A states its an internal leak in the master
cylinder. Tech B says it is siezendes wheel cylinder pistons. Who is right? - ANS Tech A-
internal leak in the master cylinder - fluid bypassing the master cylinder primary cup may cause
the pedal to go to the floor.
Car pulls to the right without braking, but pulls to the left when during braking. What is the
cause? - ANS Broken/ Collapsed right brake hose
Tech A states that the bleeder valve on the caliper should be opened when collapsing a caliper
piston. Tech B states the brake hose should be clamped when collapsing a caliper piston. Who's
right? - ANS Tech A- The bleeder valve should be opened when collapsing a caliper piston to
prevent contaminated fluid going back to the hydraulic system.
Tech A states DOT 5 brake fluid can be substituted where DOT 3 brake fluid is specified. Tech B
states a scan Tool may be required to bleed the brakes on some cars. Who's right? -
ANS TECH B- some cars with ABS or TCS may need a scan tool to activate the system properly
to bleed brakes.
A vehicle has low brake pedal- what is the cause? A) stuck-open metering valve B) stuck-open
proportioning valve C) seized caliper piston D) seized Star adjuster - - ANS D- seized star
adjuster- a seized star adjuster will lead to excessive clearance between the brake shoes and
the drum, requiring additional pedal travel.
A primary shoe of a rear brake drum is worn on the top and secondary shoe is worn on the
bottom. What could be the cause?- weak return springs or a seized wheel cylinder piston , or
Weak hold-down springs? - ANS Weak hold-down springs
A vehicle has pulsating brakes: Tech A says excessive lateral run out would cause this. Tech B
says a rusty hub flange would cause this. Who's right? - ANS Both techs

, A vehicle pulls to the right during braking. What could cause this? - ANS A seized left front
brake caliper.
True or False: wheel bearing grease should be used to lubricate brake caliper pins and slides,
backing plate contact points. - ANS False
The brake caliper should be replaced, if: A) seized caliper mounting bolt B) damaged caliper
mounting bracket C) contaminated brake fluid D) leaking copper washers - ANS C- replaced
brake caliper if it has contaminated brake fluid
The inboard brake pad of a singular piston caliper is worn more than the outboard pad. Tech A
states a stuck-applied caliper piston is the cause. Tech B states siezed caliper slides. Who's
right? - ANS Tech B- seized caliper slides. Stuck-applied caliper piston would apply pressure
evenly to both brake pads. A siezedcaliper slide would prevent the outboard pad to apply,
causing the inboard pad to wear out more.
The primary shoe of the rear drum brake system is worn on top and the secondary drum show
is worn on the bottom. What is the cause? - ANS Weak hold down springs
Car has a low brake pedal. What could be the cause?: stuck open metering valve, stuck open
proportioning valve, a siezed caliper piston, or a siezed star adjuster? - ANS Siezed star
adjuster - it will lead to an excessive clearance between the brake shoes and the drun
During a test drive the technician finds the brake drags- during the inspection when the engine
off, the technician finds that the wheels turn freely, what could be the cause? - a plugged brake
booster vaccuum line? A sticking brake master cylinder? A sticking brake pedal assembly? A
plugged brake booster vent? - ANS Plugged brake booster vent: no vacuum to the booster
will cause a hard pedal, a sticking master cylinder or brake pedal will cause the brakes to drag
with engine ON and OFF, but a plugged brake booster vent will keep the brake pedal applied by
not allowing pressure to equalize.
