In a thyristor-controlled injection braking unit, the voltage to be injected into the motor stator winding is obtained by rectifying the supply voltage. Two thyristors are connected as a phase controlled rectifier (PCR). The braking torque depends on the magnitude of the current, which can be varied by phase control of the thyristors.
For the tests the vehicle brake for which the replacement linings are designed is installed in an inertia dynamometer instrumented for continuous recording of rotative speed, brake torque, brake line pressure, number of rotations after brake application, braking time, and brake rotor temperature.

Maximum brake torque (MBT) is the use of optimal ignition timing to take advantage of an internal combustion engine's maximum power and efficiency. There is always an optimal spark timing for all operating conditions of an engine. MBT is ideal at wide-open throttle (WOT), but not desirable when the engine is at idle.
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.
The driver requests the torque or engine speed requirements via accelerator pedal potentiometer thereby sending a signal to the engine ECU which then, depending on its mapping and data collected from various sensors, calculates in real time the quantity of injected fuel required, thus altering the fuel rack to the required position.
