Install Hydraulic Brake Control Cables
S 434-016
(1) Put the replacement cables (E, F, G, and H) through the fairleads and connect them to their related control quadrants (3) of the brake metering valve.
NOTE: You can mix zinc-only coated cables and tin-over-zinc coated
____ cables if you replace the opposite cables in a given cable loop with cables of the same type. For example, in the brake control cable loops, Figure 401, if you replaced Cable A (LGBA1), you must make sure the Cable B (LGBA2), Cable C (LGBB1), and Cable D (LGBB2) are all of the same type. This will prevent asymmetric cable stretch that can degrade the cable rigging.
