The A400 is an arm style caliper brake designed to accept a large selection of Hilliard thrusters. These thrusters include spring applied hydraulic released, spring applied pneumatic released, hydraulic applied spring released, and pneumatic applied spring released. The 400 requires a minimum disc diameter of 24" and is off ered in 2 sizes to accommodate a 1" and 1-1/2" thick disc. The design of the caliper allows the user to quickly convert between right and left handed designs eliminating the need for multiple part numbers.

The AS thruster is a direct applied thruster that is pneumatically applied spring released. The Pneumatic applied thrusters are offered in multiple sizes to meet the needs of our customers. The T400 AS thruster produces a maximum braking force of 8400 pounds at the maximum operating pressure of 67 psi. (This
thruster is only to be used on the A400 caliper)

The A300 is an arm style caliper brake designed to accept a large selection of Hilliard thrusters. These thrusters include spring applied hydraulic released, spring applied pneumatic released, hydraulic applied spring released, and pneumatic applied spring released. The A300 requires a minimum disc diameter of 12" and is offered in 4 sizes to accommodate a ½", 1", 1-3/16", and 1-1/2" thick disc. The design of the caliper allows the user to quickly convert between right and left-handed designs eliminating the need for multiple part numbers. 

The HS thruster is a direct applied thruster that is hydraulically applied spring released. The T300 HS thruster produces a maximum braking force of 3200 pounds at the maximum operating pressure of 1400 psi. (When used with the A300 Caliper)
