Chapter 1 Flashcards
______________ braking systems use electrical generators to help slow the vehicle during gradual stops and help recharge the electric batteries.
REGENERATIVE
The _______________ _______________ is mounted on a lever with a pivot near the top of the lever.
BRAKE PEDAL
Modern automotive _______________ _______________were developed from aircraft brakes of World War II.
BRAKE PADS
Disc _______________ _______________ are mounted in a caliper that sits above the spinning rotor.
BRAKE PADS
The _______________ _______________ is the start of the brake hydraulic system.
MASTER CYLINDER
All master cylinders for vehicles built since 1967 have _______________ _______________ and pumping chambers
2 PISTONS
There are two types of split systems: _______________ and front/rear.
DIAGONAL
The electronic function of the proportioning valve has been called “_______________ _______________ _______________” and “_______________ _______________ _______________” by various manufacturers
“DYNAMIC REAR PROPORTIONING”
“ELECTRONIC BRAKE DISTRIBUTION”
Most systems with drum brakes have a single, _______________ cylinder at each wheel.
TWO-PISTON
The ABS does the same thing as an _______________ _______________ would, only it does it faster and more precisely.
EXPERIENCED DRIVER
Technician A says all the friction components of a disc brake are exposed to the airstream. Technician B says this helps to cool the brake parts and maintain braking effectiveness during repeated hard stops from high speeds. Who is correct?
A. A only C. Both
B. B only D. Neither
BOTH
Technician A says that with a fixed caliper, hydraulic pressure is applied to pistons on both sides to force the pads against the rotor. Technician B says that with a movable caliper, pressure is applied to a piston on the outboard side only. Who is correct?
A. A only B. B only
C. Both
D. Neither
A ONLY
Technician A says drum brakes do not develop the mechanical servo action that you will learn about as you study drum brakes. Technician B says drum brakes require higher hydraulic pressure and greater force to achieve the same stopping power as a comparable disc brake. Who is correct?
D NEITHER
While discussing the brake stroke sensor, Technician A says the brake stroke sensor informs the brake controller how fast the brake pedal is being pushed down. Technician B says the stroke sensor also informs the controller how much pressure the driver is applying to the brakes.
C BOTH
Technician A says the stroke simulator is used to make hybrid brake application feel normal to the driver. Technician B says the stroke simulator is an electrical switch for the brake lamps. Who is correct?
A ONLY
Technician A says that all new vehicles have metering and proportioning valves. Technician B says that the function of these valves has been taken over by the ABS system on most vehicles. Who is correct?
B ONLY
While discussing wheel cylinders and caliper pistons, Technician A says wheel cylinders of drum brakes operate in response to the master cylinder. Technician B says the caliper pistons of disc brakes operate in response to the wheel cyl- inders. Who is correct?
A ONLY
