Installation and Maintenance Manual

Fig. 2: CB8-E
The main components of the brake calliper are as follows:
Housing:
The brake is mounted with three bolts M16 on a base frame or sub-construction.
Brake lever:
Hinged with the brake shoes, they surround the brake disc and apply the braking
force. When releasing the brake, the embedded restoring springs lift the brake
shoes from the disc.
Thrustor:
The thrustor is used to open the brake and is acting against the spring force. The
energy required for release is generated electro-hydraulically. The release force is
transmitted to the square part by the release lever and the stud.
Readjusting unit: The readjusting unit is used for compensation of lining wear, however its
compensating capacity per braking cycle is limited. Therefore an additional manual
wear compensation carried out by maintenance personnel is required according to
the specific application.
Spring:
The helical compression spring generates the brake force and pushes the square
part back. The rollers transmit the brake force with low friction to the brake levers.
