2. DC injection braking - Wikipedia

   en.wikipedia.org/wiki/DC_injection_braking

   Large rotors and loads with a high moment of inertia may take a significant amount of time to stop through internal friction alone. To reduce downtime, or possibly as an emergency safety feature, DC injection braking can be used to quickly stop the rotor. A DC injection brake system can be used as an alternative or addition to a friction brake ...

3. Brake pad - Wikipedia

   en.wikipedia.org/wiki/Brake_pad

   Brake pads should be checked at least every 5,000 miles for excessive or uneven wear. Although brake pad wear is unique to each vehicle, it is generally recommended that brake pads be replaced every 50,000 miles, [6] while brake discs (or rotors) typically last longer, needing replacement every 70,000 miles.

4. Drum brake - Wikipedia

   en.wikipedia.org/wiki/Drum_brake

   Drum brake (upper right) with the drum removed (lower left, inside facing up), on the front of a Ford Falcon Sprint A rear drum brake on a Kawasaki W800 motorcycle. A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating bowl-shaped part called a brake drum.

5. Disc brake - Wikipedia

   en.wikipedia.org/wiki/Disc_brake

   A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc (sometimes called a [brake] rotor) [1] to create friction. [2] There are two basic types of brake pad friction mechanisms: abrasive friction and adherent [ further explanation needed ] friction. [ 3 ]

6. Electromagnetic clutches and brakes - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_clutches...

   Similarly, two-piece brakes that have separate armatures should be burnished on a machine rather than a bench because any change in the mounting tolerance as that brake is mounted to the machine may shift the alignment so the burnishing lines on the armature, rotor or brake face may be off, slightly preventing that brake from achieving full torque.

7. Eddy current brake - Wikipedia

   en.wikipedia.org/wiki/Eddy_current_brake

   Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...
