Brake discs are generally manufactured from grey cast iron, although some high performance vehicles can have ceramic-based or carbon fibre-based disc. The disc is bolted to the wheel hub; therefore the disc rotates at the same speed as the road wheel. The brake disc friction surface is exposed to the atmosphere; so the air flow around the disc as the vehicle moves cools the discs. The brake disc is either of a solid or ventilated type.

A brake is a machine element used for applying a force to a moving surface to slow it down or bring it to rest in a controlled manner. In doing so, it converts the kinetic energy of motion into heat, which is dissipated into the atmosphere. Brake is used in motor vehicles, trains, airplanes, elevators, and other machines. It is usually of a friction type in which a fixed surface is brought into contact with a moving part that is to be slowed or stopped.

A brake is a device for slowing or stopping the motion of a machine or vehicle, and to keep it from starting to move again. The kinetic energy lost by the moving part is usually translated to heat by friction. Alternatively, in regenerative braking, much of the energy is recovered and stored in a flywheel, capacitor or turned into alternating current by an alternator, then rectified and stored in a battery for later use.

Bronze Gear Pumps provides compact footprint with close-coupled design. It has maintenance friendly assembly to a variety of motor frames and rugged construction. The pumps are suitable for all liquids that are compatible with bronze. It provides long service life through the design and chosen materials of construction. Systems have gear pump head mounted to a standard ODP motor. It is suitable for Pumping Water, Oils and Select Solvents. It feature self-lubricating bronze gears and carbon-graphite bearings, making the FPUGR100 pumps ideal for non-lubricating liquids such as water and certain solvents. It has gear within a gear design is used for quiet operation. It's built in gear reduction fully supported through-shaft design that utilizes standard motor speeds. It has universal built in shaft seal flexibility. It has two moving parts reduces maintenance and wear.

Bucket Pumps are ideal for filling open and sealed reservoirs, compressed air lubricators, gearboxes and centralized lubrication equipment. It has an adjustable lever adapts pump to lubricant type and operating conditions. It develops from 2,500 to 5,000 psi. It is a self-priming, pushdown action pump that fits 5-gallon pails. It also has a drain-back nozzle that prevents spills and accidents.
