Brinelling (Definition). One or more indentations on bearing races usually caused by high
static loads or application of force during installation or removal.
Brinelling on a bearing that has been shocked loaded, the race(cup) of the bearing can be
dented. what is this type of bearing failure called?
the front brake rotors and pads are being replaced on a vehicle equipped with a tcs and esc.
Technician A says the yaw rate and deceleration sensor should be recalibrated. Technician B
says the new rotors should be indexed to the hub using a dial indicator for the least amount of
runout. who is right? B only
The ABS (antilock brake system) amber light does not go off after the engine is started.
Technician A says a parking brake not fully released could be the cause. Technician B says when
this happens the brakes will operate like a normal non-ABS brake system. Who is right? B
only
If the amber light is on it indicates an ABS fault and the system will revert to regular brake
operation without ABS. Technician A is wrong because the parking brake only affects the RED
Brake Light not the amber.
A wheel speed sensor is being diagnosed using the OEM (original equipment manufacturer)
diagnostic scan tool. Technician A says to verify wheel speed sensor operation, compare all four
wheel speed sensor outputs to vehicle speed on the data list. Technician B says the wheel's
direction of rotation can be verified by looking at the wheel direction on the scan tool data list.
Who is right? Both A and B
The ABS (antilock brake system) and TRACTION OFF indicator lights remain ON with the engine
running. Technician A says to check for ABS or TCS (traction control system) diagnostic trouble
codes. Technician B says you can check for ABS or TCS blink codes by connecting two pins of the
DLC (Data Link Connector). Who is right? Both A and B
, The front wheel bearings are being adjusted. Technician A says you torque the adjusting nut to
a specified torque and back off the nut till it lines up with the hole and install the cotter pin.
Technician B says backing off the castle nut will cause the bearing to overheat. Who is right?
A only
Technician A says a defective wheel or axle bearing can make a growling or rumbling noise.
Technician B says a defective wheel displays looseness or excessive play in the steering wheel
especially while driving over rough road surfaces. Who is right? Both
The component in the Figure is involved what procedure? Replacing sealed wheel bearing
When performing a vacuum booster function test, you should begin by pumping the brake
pedal several times _______________. with the engine off
Technician A says the vacuum supply test involves inspecting the vacuum supply hose for kinks.
Technician B says the test involves checking the level of vacuum supplied by the engine or
vacuum pump. Who is right? Both
With the brakes applied on a vehicle with power brakes, the pedal moves down slightly when
the engine is started. Technician A says the cause could be a leaking power brake booster
diaphragm. Technician B says the cause could be a stuck closed residual check valve in the hose
from the intake manifold to the power brake booster. Who is right? Neither A nor B
Both technicians are wrong because this is how power brakes are supposed to operate.
A vehicle comes in with a complaint of excessive pedal travel before the brakes apply.
Technician A says the master cylinder pushrod adjustment is incorrect. Technician B says the
cause is a faulty residual pressure check valve admitting air. Who is right? Tech A only
