Actuation system for a motor

A hydraulic motor assembly comprising:

• a housing;
• a hydraulic piston assembly positioned in the housing, the hydraulic piston assembly comprising a cylinder block;
• a pair of braking pads positioned around the cylinder block;
• an actuator system coupled to the pair of braking pads;
• and
• a hydraulic block fluidly coupled to the hydraulic piston assembly and the actuator system;
• wherein a flow of fluid from the hydraulic block to the actuator system selectively controls a compression of the pair of braking pads on the cylinder block.

A method of operating a brake assembly for a hydraulic axial piston motor, the brake assembly comprising a cylinder block and a pair of braking pads positioned around the cylinder block, the method comprising:

• receiving a user input;
• adjusting a flow of hydraulic fluid through the hydraulic axial piston motor based on the user input;
• and
• in response to less than a threshold pressure:
• decompressing a first spring supporting a first piston and a second spring supporting a second piston;
• compressing the pair of braking pads against the cylinder block;
• and
• reducing rotation of the cylinder block;
• and
• in response to greater than threshold pressure:
• compressing the first spring supporting the first piston and the second spring supporting the second piston;
• releasing the pair of braking pads from compression against the cylinder block;
• and
• increasing rotation of the cylinder block.
