Page 10: Cleaning The Brake Disc
Brake linings can be supplied with several lining materials in two different types, depending on the brake size and/or application. All brake linings supplied by SIBRE are asbestos free and free of lead. In general two types of lining materials are available: ... -
Page 11: Mounting Of The Brake - Initial Setup On Site
B06 20 243 E-EN page 11 / 23 Installation and Maintenance Manual 09.2010 CB8-E Sinter brake linings are less sensitive to dirt, grease and oil and can in some cases - where not fully soaked up with oil - be cleaned with solvent and re-used. WARNING Solvent cleaners can be flammable, poisonous and can cause burns. - Page 12 B06 20 243 E-EN page 12 / 23 Installation and Maintenance Manual 09.2010 CB8-E WARNING The manual release is spring biassed to realize an auto-kickback functionality. The activated manual release will jump back in its initial position automatically by spring force, when the brake is released by solenoid the next time.

Page 13: Manual Release
B06 20 243 E-EN page 13 / 23 Installation and Maintenance Manual 09.2010 CB8-E CAUTION The full torque is only generated after bedding in of the linings. The contact pattern must be minimum 70% for operation. 4.9 Manual release The disc brake CB8 is provided with an eccentric manual release in series. The handling of the manual release is carried out as follows: Remove the sidewise cap (figure 7a) Rotate the eccentric shaft clockwise until the indexed position is reached (figure 7b). -
Page 14: Adjustment Of Reserve Stroke
B06 20 243 E-EN page 14 / 23 Installation and Maintenance Manual 09.2010 CB8-E 4.10 Adjustment of reserve stroke The reserve stroke avoids, that the brake gets "on block" position and no more braking force is transmitted to the disc any more. Without counteraction the reserve stroke would decrease with increasing lining wear. -
