ASE BRAKES (A5) #1 Questions with Correct Answers |New Update 100% Verified By Experts
a brake system has a soft, sinking pedal with the engine running. brake fluid level is at correct
height. what's the cause? bypassing master cylinder. a bypassing master cylinder would
cause a low pedal and would not cause a loss of fluid.
master cylinder being bled prior to installation ...
when bench bleeding a master cylinder, you should use ___ _____ _____. new brake fluid.
what would the normal pressure reading be during moderate brake pedal application, with
engine running on this illustration? 900psi is normal. (100 psi is too low, 3000psi too high for
moderate brake pedal pressure, 5000psi extremely high for moderate pedal pressure)
what causes a vehicle to pull left after the brake pedal is released? a restricted left front
brake hose would cause this because it leaves the left front caliper applied after the brake
pedal is released.
compression fittings should never be used on _________ _____ _____. hydraulic brake lines
if a steel brake line fails, it should be repaird with a new section of line using either ___ __
______ ____. ISO or double flare.
what is this an illustration of? abs modulator valve or combination valve. combination valve
if the rear wheels of a front wheel drive car lock up during heavy braking, what's could be the
cause? a faulty proportioning valve. it could cause the pressure to the rear wheel sto be too
high and lock the wheels during hard braking
the pressure differential valve lights the red brake warning light when... there is a pressure
imbalance. it causes the switch to illuminate the light.
, what is the result of a caliper piston seal leaking? brake pedal will become soft as the fluid
got low. air will enter the system.
what would cause a brake fluid leak on a front disc brake caliper assembly? piston seal. a
faulty piston seal would cause a leak.
brake fluid should be stored in __________? small tightly sealed containers
what causes brake chatter? contaminated linings. they cause brake shoes to stick & slip,
causing a chattering condition.
a spongy pedal is the result of _____________? leaking wheel cylinders. this lets air get into
the hydraulic system resulting in a spongy pedal..
what causes drum chattering on the brake lathe? failure to install the dampening belt. a
missing dampening belt could cause the drum to vibrate while on the lathe. the vibration would
cause the drum to bounce on the cutting tip & make a chattering noise
what causes a low, firm brake pedal? improperly adjusted brake shoes. this causes the
wheel cylinder pistons to travel further, thus causing a low firm brake pedal.
what causes brake drag? weak return springs
what could cause pedal pulsation after replacing rotors? a wheel torque that is too tight. it
could warp rotors resulting in pulsation.
what causes a vehicle to pull right while braking? a seized left caliper slides would cause a
lack of braking force on the left side. the right side has higher braking force causing the vhicle to
pull to the right.
