A4 & AA4

Hydraulic

Description:

The Carlisle A4 and AA4 brakes are hydraulically applied, four-piston, caliper disc brakes designed for a variety of dynamic braking requirements. These brakes are typically mounted to a flange on the vehicle's axle or mounting bracket for service brake applications.

Application:

Mobile construction and mining equipment, agricultural machines, logging industry vehicles, Industrial equipment.

Formulas:

Torque (lb-in) = K x Pressure (psi) x Disc Friction Radius (in)

Torque (N-m) = K x Pressure (bars) x Disc Friction Radius (mm)

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

Friction Radius (mm) = Disc Diameter (mm)/2 - 38.1 mm
