Trailer Brake - Slotted

A displacement-type, single-acting hydraulic cylinder designed specifically for mechanical parking brake applications on agricultural trailers. It incorporates an internal compression spring that automatically returns the piston to the ‘brakes off’ position when hydraulic pressure is released.

This cylinder is supplied with a slotted clevis yoke, allowing free axial and angular movement, accommodating linkage misalignment and trailer flex during operation.

Features

• Type: Displacement, single-acting hydraulic cylinder
• Return Mechanism: Internal compression spring
• Default Position: Brakes OFF (spring extends piston when pressure is absent)
• Mounting: Includes slotted clevis yoke for flexible linkage connection
• Application: Mechanical parking brake systems on agricultural trailers

Benefits

• Fail-safe return to brakes-off position when pressure is removed
• Durable construction for off-road and harsh environments
• Simple integration with mechanical drum brake linkages
• Compensates for alignment variations via slotted clevis design

Typical Use Case

Mounted on the trailer chassis or axle, this cylinder connects to a mechanical brake linkage. When hydraulic pressure from the tractor is applied, the cylinder extends to apply the brakes. When pressure is released, the internal spring returns the piston, disengaging the brakes.
