A brake pedal that slowly goes to the floor when the brakes are applied, with the engine off, with no fluid loss could indicate the
master cylinder is defective
brake pads or brake shoes may be worn out
power brake booster is defective

When turning a scored brake drum, the maximum oversize limit for MOST automobiles would be
0.030 inch
0.060 inch
0.090 inch
0.110 inch
The number 10.090 cast into the brake drum refers to the
minimum diameter of the drum
discard diameter
original size of the drum

A high hard brake pedal and excessive stopping distances could indicate.
low brake fluid
a defective power brake booster
air in the hydraulic brake system
brake pads may be worn out
Vacuum-assist power brake units have __________reserve stops

When using manufacturer's diagnostic routines for traction control,
the technician can retrieve DTCs by using scan tools
DTCs can be ignored if they do not match customer's symptom
DTCs symptom charts are only a suggested diagnostic route
visual inspection may be eliminated if DTCs are present
When following a manufacturer's diagnostic routine, which of the following is correct?
DTC is the last step in diagnosis process
Diagnosis by symptom charts is helpful if no traction control DTC is present.
Basic brakes and engine concerns do not affect traction control performance
Traction control only works in cold weather states
When using manufacturer's diagnostic material, it is TRUE that
a general description of the system is USUALLY found in the beginning of the diagnostic section
failure to follow flow charts will usually result in repairing vehicles
known good components means that
defective parts may be substituted for diagnostic purposes
no DTCs means the system is okay

single-piston fixed
A disc brake rotor's total indicated runout reading should be
0.005 inch or less
between 0.006 inch and 0.039 inch
between 0.040 inch and 0.06 inch
disregard
When checking for parallelism on a disc brake rotor, the technician should use a
tape measure
micrometer
dial indicator
linear caliper
For lateral runout, a technician should use a
tape measure
micrometer
dial indicator
linear caliper
What component is the heart of the anti-lock brake system (ABS)?
electronic controller
reservoir
booster
solenoid body
An ABS system will
decrease braking force on selected wheels
increase the braking distance on high-traction surfaces
always reduce braking distance on bitumen-surface roads
decrease braking distances on gravel and snow
