HYDRAULIC CALLIPER TYPE NHCD-1400
Instructions for assembly, adjustment and maintenance
T.D.S.: BC.TDS.00025I
Rev.0.: September - 2012
2.3.6.
Make the hydraulic feed connections of the brake. Each semi-calliper has 2
connections with a 3/8”G thread for the hydraulic feed. Remove the plugs from
the 3/8”G holes to which the hydraulic feed tubing is to be connected. It is
recommended to use the lower connection, leaving the upper one free to fit a
purging device, and if there is not one, leave the steel plug mounted.
2.3.7.
After fitting the hydraulic connections, apply 2 Mpa of pressure to the brake to
bleed the air out of it. The purging of air out of the 3/8”G hole is done without
hydraulic feed. In the event of not having the option of fitting a minimex outlet,
the brake air can be bled out through the upper feed connection, by unscrewing
the steel plug until oil comes out. At that time we will know that there is no longer
any air in the brake, so we can screw the plug back on.
2.3.8.
After bleeding the air out of the brake, proceed to adjust the brake, according to
point 4 of the instructions.
Important: Never apply more than 2 Mpa of pressure to
the brake during the brake bleeding procedure as this
could dangerous for the worker performing the operation.
