When releasing the brake the bolt 8, the adjusting nut 3, the gear ring 2 and the pistons 5
squeeze back inside. As the pin 4 bumps the helical groove “A”, the adjusting nut 3 and the gear
ring 2 turn for one tooth coupling pitch. The adjusting nut 3 moves the bolt 8 outside through the
thread, thus decreasing backlash appeared due to brake lining wear.
Through the tooth coupling “B” adjustment is made with very little speed - evenly with
the pitch of 0.03 mm.
