Extreme care must be taken not to overheat the disc during the process. On water cooled discs it
may be necessary to limit the flow of cooling water in order to achieve the necessary disc
temperature for effective burnishing.
Disc temperature must not exceed 700
°
F (371
°
C) or permanent degradation
of the lining may occur.
Burnishing is best achieved by applying the maximum torque and minimum speed that the drive
can tolerate. Depending on the configuration of the brake system it may be necessary to reduce
the burnishing torque by;
a)
Partially applying the brake with fluid pressure to a level that the drive can tolerate, or
b)
In systems with more than one brake, isolate all but one brake and burnish one brake at
a time.
Three important points to consider when burnishing are;
i.
The temperature of the disc must be closely monitored. Excessive heat will damage the
friction linings.
ii.
The duration of burnishing varies with each application.
iii.
Burnishing is not complete until the brake is producing rated torque. This will be
indicated by the motor current while burnishing.
Failure to properly burnish will not allow the brake to produce adequate
torque for the intended duty.

Before putting equipment into service, confirm that full rated braking torque has been achieved
through load testing or a torque test against the drive motors. If full brake torque has not been
achieved, continue burnishing.
