2-4 Brake, Low and Reverse Brake

2-4 BRAKE, LOW AND REVERSE BRAKE

2-4 Brake, Low and Reverse Brake:

2-4 Brake
When hydraulic pressure is applied between the servo retainer and the servo piston (brake band engagement side), the servo piston overcomes the spring force and acts on the brake band, thus locking the 2-4 brake drum. When hydraulic pressure is applied between the servo piston and the transaxle case (brake band disengage side), the servo piston is pressed toward the servo retainer side. The brake band expands by its own spring force, thus releasing the 2-4 brake drum. When hydraulic pressure is applied simultaneously between the servo retainer and the servo piston and between the servo piston and transaxle case, the servo piston is pressed to the servo retainer side as a result of the difference of the surface area between the two, thus releasing the 2-4 brake drum.

Note: This brake operates during second gear and fourth gear.

Low and Reverse Brake
When hydraulic pressure acts on the brake piston, the drive plates and the driven plates are pressed tightly together, and the transaxle case and the low and reverse brake inner race are connected. The rotation of the planetary carrier is locked when the low and reverse brake is activated.

Note: This brake operates during 1 range first gear and R position.
