Hydraulic Brake Systems Flashcards
When converting kPa to PSI the kPa must be divided by what number
Seven
What best describes a brake pad wear indicator
Usually small thin metal tangs
Describe kinetic friction
Kinetic friction occurs between two surfaces that have relative motion between them
Pressure applied to a confined liquid is transmitted equally and undiminished in all directions at right angles to all surfaces. Who’s law is this?
Pascal’s
Briefly describe an internal shoe type activated park brake system
It uses a drum with internal friction
Parking brakes are designed to hold the vehicle securely in place when left unattended and assist to provide full stopping power. true or false
False
Double flared lines used with steel tubing can be interchanged. True or false.
False
What happens to the power piston return spring in a hydraulic booster operation when it’s in the applied position
The power piston return spring compresses
What are two types of brake pads
Bonded and riveted
What position is the compressed air valve and exhaust port in when a power booster air pack system is in the released condition
The compressed air valve is closed and the exhaust port is open
The brake system is considered what type of system
Hydrostatic
What term refers to heat transfer that applies to liquids and gases.
Convection. Conduction. Induction. Or radiation
Convection
What’s the purpose of a proportioning valve
It is used to control rear braking action
