3k1367 Cylinder A — Cat

This cylinder is a key actuator within the braking system, utilizing hydraulic pressure to apply force to the brake components. It is built to meet Caterpillar's rigorous standards, offering reliable operation and consistent performance, unlike a worn cylinder which may leak fluid or fail to apply adequate pressure. Operators might experience a soft or spongy brake pedal, or the brakes may not engage properly when this component is malfunctioning.

Installation & Application Notes

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing brake cylinder may initially present as a gradual loss of braking power or a pedal that feels softer than usual. If left unaddressed, the cylinder can develop internal or external leaks, leading to complete brake failure. This can significantly impair the operator's ability to control the machine, especially on inclines or during heavy-duty operations.

Installation Tip

Ensure all hydraulic lines are properly flushed and free of contaminants before connecting them to the new cylinder. Avoid introducing air into the hydraulic system during installation, as this will require extensive bleeding.

Service Note

Inspect brake fluid, lines, and associated seals for wear or leaks when replacing the brake cylinder.
