Step 6
Locate the small weep hole in the brake cover near the hole for the protective
tubing. It may be painted closed and easier to locate from inside the cover. Use
the 1/16 inch drill bit to drill a 1/16 inch hole enlarging and cleaning out this
existing hole. This weep hole is essential to allow equalization of pressure
inside the brake. After drilling, wipe inside of cover removing any shavings or
debris. Refer to Figure 6.
Step 7
There are two ways the cover may be installed. Install the brake cover with the
weep hole facing down. Use the nylon washers under the wing nuts to provide a
water-tight seal as detailed in Figure 7.
This completes the replacement of the azimuth brake assembly. The antenna
control power should now be turned back on and the azimuth axis rotated to
verify proper brake release and operation.
