Replacing the Brake
Each front end motor contains a brake assembly to stop the table or sweep quickly and precisely. The brake
is an independent auxiliary device that should require little or no service other than cleaning. If a brake fails,
the entire brake should be replaced since none of its internal components are user replaceable.
Note - It is recommended that you check the condition of the hubs when replacing a brake, and if needed,
replace the hubs and the key with new parts.

Brake Mechanism
5.
Remove the brake by removing the three socket head screws that secure it (see the drawing on page
15). These screws can be accessed through holes in the top of the brake housing.
The hexagonal hub (used for manually cranking the motor) and the splined hub (used by the brake) do
not need to be replaced unless they are excessively worn or damaged. The manufacturer supplies a
splined hub with each brake. When replacing the hubs, replace the key as well. The part numbers for
the hexagonal hub as well as the key can be found at the back of this section. To replace the hubs,
follow the applicable steps in Section 2.3.3, Replacing the Encoder Assembly.
6.
Align the splined hub with the spline in the new brake and place the brake on the encoder enclosure
such that the straight edge of the brake’s mounting flange is next to the motor plug, and fasten the
brake in place with the three socket head cap screws.
7.
Reconnect the brake cable and the motor’s power cable.
8.
Restore power to the pinspotter.
9.
Run the sweep to the Home position.
10.
Cycle the pinspotter and observe for correct operation.
