Inserting tool into the hole; aligning tabs with slots

Insert release tool into the hole in the back of the brake chamber by aligning the tabs on the tool with the
slots on the brake chamber.
Turning release tool clockwise

Applying slight inward pressure, turn the release tool clockwise ¼ turn with 11/16" wrench until it locks in.
Remove one of the nuts and tighten the other nut to fully compress the internal spring. You will feel a
moderate resistance while the spring is being compressed. The nut should be tightened several turns until it
bottoms out and increased resistance is felt. DO NOT OVER TIGHTEN! The spring is now caged and it is safe
to remove the chamber.
