Base Brakes
Convert kinetic energy into heat energy?
What is friction?
A component that produces fluid pressure across all wheels.
What is a Master Cylinder?
Small pieces of metal that cushion the brake pad and absorb some of the vibration, helping to cut down on unwanted noise.
What is brake pad shims?
Type of brake shoe arrangement where one shoe is positioned in a leading manner and the other shoe in a trailing manner.
What is leading/trailing drum brake system?
The valve in the HCU that either allows or blocks brake fluid that comes from the master cylinder from entering the HCU hydraulic circuit.
What is the isolation valve?
It is light amber in color and readily absorbs moisture.
What is brake fluid?
A substance that attracts and absorbs water (e.g., brake fluid).
What is hygroscopic?
A metal disc designed to receive friction pressure from brake pads in order to stop a vehicle.
What is a rotor?
A system that uses servo action in both the forward and reverse direction.
What is a duo-servo drum brake system?
A computer-controlled system added to ABS to help prevent loss of traction while the vehicle is accelerating.
what is the traction control system?
This brake fluid contains Silicon
What is DOT 5?
A bleeding method where one person manually operates the brake pedal while the other person opens and closes the bleeder screws on the wheel brake units to allow the air and old brake fluid to be pushed out.
What is manual bleeding?
A metal plate to which the brake lining is fixed.
What is the backing plate?
A component of the backing plate that takes all of the braking force from the brake shoes.
What is an anchor pin?
An electrically operated valve, which in brake systems is used to control the flow of brake fluid in the hydraulic system.
what are electric solenoids?
Another name for brake shoes.
What is brake linings?
The force applied to the input piston, measured in either pounds or kilograms.
What is Input force?
A hydraulic device that uses pressure from the master cylinder to apply the brake pads against the rotor.
What is a brake caliper?
Brake shoes installed so that they are applied in the opposite direction to the forward rotation of the brake drum; not self-energizing and less efficient at developing braking force.
What are trailing shoes?
A device that measures the amount of roll around the vehicle’s horizontal axis that a vehicle is experiencing.
What is the roll rate sensor?
A system of hydraulic and mechanical components designed to slow or stop a vehicle.
What is the brake system?
A valve that monitors any pressure difference between the two separate hydraulic brake circuits; it usually contains a switch to turn on the brake warning light when there is a pressure difference.
What is the pressure differential valve?
Both surfaces of the rotor are not perfectly parallel to each other so that brake pulsations occur.
What is lateral runout (warping)?
A system on drum brakes that automatically adjusts the brakes to maintain a specified amount of running clearance between the shoes and drum.
What is the automatic brake self-adjuster?
A storage container designed to contain high-pressure liquids such as brake fluid.
What is the accumulator?
