9 Brakes Flashcards
Where are disc breaks found
Are not just found in airbrakes
Service brakes
Take some kind of mechanical force and apply it to the wheels to stop the rotation
Park brakes
Uses an implied mechanical force to keep a vehicle in place when parked
Hydraulic brakes
Transverses power, via brake fluid
Common with light vehicles , tractors, ATVs, and older apparatuses
Airbrakes
Transfer power to the brakes be a compressed air
Common with heavy trucks, buses industrial machines, and tractors
Hydraulic brakes consist of
Brake pedal
Master cylinder
Brake lines
Calliper or piston
Brake shoes and pads
Master cylinder
Is the oil reserver
How do you hydraulic brakes work?
When the driver pushes the brake pedal the master cylinder converts, mechanical pressure into hydraulic pressure and send it through each brake line at each wheel. A slave cylinder converts the hydraulic pressure back to mechanical pressure. A parachute is pushed against the drummer of the desk to add friction to slow the wheel.
Do hydraulic brakes have delay
Virtually no delayed reaction because it is virtually incompressed
Park brake
Also known as emergency break, is a manual spring break on hydraulic brakes
Airbrakes air compressor
Air, compressor and governor
Air compressor cousin at 100 psi
Air compressor cuts out at 125 psi
The storage tanks
The air compressor is connected to a Reservoir that stores pressurized air, the secondary and primary tanks
Brake lag
Is the reaction time for when the pedal is pushed tether there is any breaking action roughly 3/10th or 1/2 seconds
How to air brakes work
When the driver pushes the brake pedal, pressured air moves through the hoses to push down a piston that move the cam that pushes a breaks you into a rotating drum that’s attached to the wheel the brake shoe rubs against the drum crates fiction and slows the wheel
2 ways to know the air breaks is charged
Gauge reads significant air pressure
