Description
 
The Carlisle HDB640 series brake is a hydraulically actuated, triple opposed piston, caliper disc brake designed for a variety of dynamic braking requirements. Both the caliper and disc require fixed mountings. This brake provides a high torque range for heavy-duty service conditions. Multiple calipers may be used on a single disc to proportionately increase torque output. Most commonly used at the wheel location with 25 inch rims.
 

Application
 
  • <p>Articulated dump trucks, front-end loaders, mobile construction and mining equipment.</p>
 

Formulas
 

English Units Torque (lbf-in) = K x Input Pressure (psi) x Disc Friction Radius (in)

Disc Friction Radius (in) = Disc Diameter (in) ÷ 2 - 1.5 (in)

K (Dynamic) = 15.3
