Band: Description and Operation

Reduction Brake Band and Band Servo





The brake band acts in response to the servo to stop the direct clutch drum rotation.

The servo has a piston that operates in response to changes in oil pressure. The piston expands in P and N ranges, 1st, 2nd, 3rd, 4th, and reverse gears to stop the direct clutch drum rotation.

When the line pressure reaches to the band servo the servo piston works. The downward piston stroke causes the piston stem to tighten the brake band. The direct clutch drum rotation stops.

The anchor end bolt is used to maintain appropriate clearance between the brake band and the direct clutch drum when the brake band is released. This clearance can be adjusted with the adjusting nut on the anchor end bolt.
