Hydraulic Dry Disc Brakes

Overview
Hydraulic Dry Disc Brakes

AxleTech hydraulic dry disc calipers are available in various sizes and mounting configurations. The 4-piston and 6-piston varieties cover a wide range of heavy duty applications including loaders, forklift trucks, off-highway rigid haul trucks, articulated haulers, reach trucks, and stationary equipment.

These high capacity calipers have a robust design and are easy to service - which can lower downtime and therefore minimize costs. The fixed caliper and disc design is easily maintained and brake pads can be replaced without removing the caliper or disconnecting the hydraulics. They can be mounted in different configurations, combinations, and on a variety of disc diameters.

Hydraulic actuation on some models is available up to 2500 psi with seal availability for either mineral oil fluids (in models designated HDM) or automotive brake fluid, non-mineral oil / DOT4 (in models designated HDA).
