Save my name, email, and website in this browser for the next time I comment. The theory is you want the coil to generate as much of a magnetic field as quickly has possible to attract the armature and start the process of deceleration. The hysteresis disk is attached to the brake shaft. The friction and the strength of the magnetic field, is what causes the rotational motion to stop. Their unique brake operating principle eliminates the need for separate control or additional switching elements. The system is safer and more reliable than regular brakes, especially when cruising at high speed. In some cases, these messages can be triggered by an electronic coolant flow valve or a lousy ignition coil. This is why they used to be referred to as Electro Mechanical clutches and brakes. If they get too far away from the drum (as the shoes wear down, for instance), the piston will require more fluid to travel that distance, and your brake pedal will sink closer to the floor when you apply the brakes. Air gap is an important consideration especially with a fixed armature design because as the unit wears over many cycles of engagement the armature and the brake face will wear creating a larger air gap which will change the engagement time of the brake. 66 0 obj <>stream You may also revoke your consent there. Burnishing is the process of cycling the brake to wear down those initial peaks so that there is more surface contact between the mating faces.
