Maximum operating pressure is 3,000 psi (206.4 Bar). Pressure spikes or surges not to exceed 3,500 psi (240.8 Bar). Surge pressure in excess of 3,500 psi (240.8 Bar) caused by spikes in the hydraulic system could shorten brake life and must be avoided. 2. Use only SAE grade 8 mounting bolts and torque to 80-90 lb. ft (108 - 122 N-m) for motor mounting. 3. PRECAUTION: Bench testing may cause distortion of components or bolt failure. Mounting bolts must be used or supplemental clamping. 4. Minimum Release Pressure is defined as the hydraulic pressure required to obtain full running clearance. 5. Cubic Inch Displacement is the volume of oil required to release the brake piston. 1.0 in3 (16.4cc) for a new brake and 2.0 in3 (32.8cc) for a worn brake pack—SAE A, B 0.7 in3 (11.5cc) for a new brake and 1.6 in3 (26.2cc) for a worn brake pack—SAE C BRAKE RATINGS MODELMOUNT TORQUE MIN.
