The hydraulic braking system is designed as a closed system: unless there is a leak in the system, none of the brake fluid enters or leaves it, nor does the fluid get consumed through use. Leakage may happen, however, from cracks in the O-rings or from a puncture in the brake line.
Sensotronic Brake Control (SBC) is an electro-hydraulic brake system developed by Daimler and Bosch. In this system, the wheel brake cylinders of a vehicle are operated through a servomechanism, offering precise and responsive braking. The SBC system was first introduced on the R230 SL-class, which was released in Europe in October 2001. [1]
The brake usually rides on a line running perpendicular to the boom; when the boom brake is actuated, it grabs the line and either works as a preventer, or slows the boom's speed while jibing. The brake is actuated by either tensioning the line upon which it rides or using a second line to tension the brake relative to the main line.
Modern versions may not only prevent wheel lock under braking, but may also alter the front-to-rear brake bias. This latter function, depending on its specific capabilities and implementation, is known variously as electronic brakeforce distribution, traction control system, emergency brake assist, or electronic stability control (ESC).
The fault could be lack of hydraulic fluid, low brake fluid in the reservoir, a broken hydraulic line or a bad master brake cylinder. The sensor is used to detect pressure differentials in the hydraulic system. If the car alerts a fault in the hydraulic system and the system checks out, the sensor itself may have failed. [2]
A small motor-boat lifted from the water by a boat lift at La Rochelle, France, 2016. Smaller devices called "Boat lifts" are available that simply raise yachts, sailboats, or small watercraft above the water level at a dock for storage, for reduced maintenance cost and increased security. They can be operated by cables, by hydraulics, or by ...
A relay valve is an air-operated valve typically used in air brake systems to remotely control the brakes at the rear of a heavy truck or semi-trailer in a tractor-trailer combination. Relay valves are necessary in heavy trucks in order to speed-up rear-brake application and release, since air takes longer to travel to the rear of the vehicle ...
An overrun brake (called a surge brake when invented) is a brake system commonly used on small trailers, where the motion of the trailer with respect to the towing vehicle is used to actuate the brake. The early systems were fitted with a spring system which was not very effective.
