Brake Systems 1 Flashcards
Brake fluid serves as a lubricant for the parts of the hydraulic system and ensures smooth and even operation.
True or false
True
All brake fluids are hygroscopic- that is, they readily absorb water.
True or false
True
Brake hoses are typically rigid steel lines that are used to transmit brake fluid pressure.
True or false
False
Fully metallic linings require very high pedal pressure and tend to quickly where out drums and rotors.
True or false
True
Brake fluid must be able to flow freely at 500°F and at -104°F.
True or false
True
A brake fluid lamp will illuminate on the instrument panel if the fluid is contaminated and needs to be changed.
True or false
False
Most manufacturers recommend changing the brake fluid periodically.
True or false
True
Master cylinders are generally not overhauled in the field. They are replaced with new or rebuilt master cylinders.
True or false
True
Residual check valves are found only on vehicles with rear disc brakes.
True or false
False
A brake line must be single flare to provide a good seal and a joint or junction block.
True or false
False
When the brakes are applied while the vehicle is moving forward, the weight of the vehicle shift toward the rear wheels.
True or false
False
Asbestos has not been used and brake linings or pounds since 2003.
True or false
True
If a master cylinder with a 1 inch bore is replaced with a cylinder with a three-quarter inch or, the pressure and the brake lines will be higher when the same amount of brake pedal pressure is applied to each cylinder.
True or false
True
If the front hydraulic circuit fails on a front/rear split brake system, the vehicle will lose 50% of its breaking power.
True or false
False
All master cylinders are made of cast iron.
True or false
False
