HySecurity MX000146, MANIFOLD ASSY, BRAKE, SA
HySecurity MX000146 is a brake manifold assembly / brake manifold kit for select HySecurity StrongArm barrier gate operator applications. HySecurity parts documentation lists MX000146 as "Brake Kit, Manifold, StrongArm 14F, 20, 28, DOT28" for StrongArm models all except StrongArm 36 / HTG 320-8.
This brake manifold kit is part of the StrongArm hydraulic pump pack and braking system. Because hydraulic braking parts affect arm control, stopping behavior, and hold performance, MX000146 should be selected only after confirming the operator model, serial number, pump pack configuration, brake manifold layout, hydraulic connections, and HySecurity parts diagram.
What This Brake Manifold Assembly Does
The brake manifold assembly is part of the hydraulic control system used to help manage StrongArm barrier arm movement and braking behavior. In the approved StrongArm hydraulic system, the manifold works with related valves, hoses, fittings, pump components, cylinder hardware, and arm-drive components to help control hydraulic flow and arm movement.
A worn, leaking, contaminated, restricted, damaged, or incorrect brake manifold can contribute to poor arm stopping, drifting, dropping, slow response, inconsistent movement, hydraulic noise, pressure problems, or oil leakage around the pump pack. Similar symptoms can also be caused by a failed brake valve, leaking cylinder, worn cylinder pin, hose or fitting leaks, low or contaminated hydraulic fluid, relief valve issues, manual bypass valve problems, pump pack wear, arm binding, or incorrect arm balance.
Compatible With
Use HySecurity MX000146 only where the operator parts diagram, original manifold, or HySecurity documentation confirms this part number.
- Select HySecurity StrongArm 14F applications where MX000146 is listed as the brake manifold kit.
- Select HySecurity StrongArm 20 applications where MX000146 is listed as the brake manifold kit.
- Select HySecurity StrongArm 28 applications where MX000146 is listed as the brake manifold kit.
- Select HySecurity StrongArmDOT 28 applications where MX000146 is listed as the brake manifold kit.
- StrongArm hydraulic pump pack repairs where the original brake manifold is marked, listed, or cross-referenced as HySecurity MX000146.
- Applications where the manifold body, valve layout, hose connections, fittings, and pump pack configuration match the HySecurity parts diagram.
Important Compatibility Warning
MX000146 is not listed for StrongArm 36 / HTG 320-8 in the StrongArm parts documentation. StrongArm 36 uses a different brake manifold kit commonly listed as MX000235. Do not assume MX000146 fits StrongArm 36 unless the current parts diagram for that specific operator confirms it.
Do not order MX000146 based only on the words "manifold" or "brake." StrongArm hydraulic systems include several related valves and pump pack parts that may connect to or mount near the manifold, but they are not the same part.

Technician Note
Before replacing MX000146, inspect the full StrongArm hydraulic system. Brake or hold problems may be caused by the brake manifold, but they can also be caused by a failed brake valve, worn check valve, leaking hydraulic cylinder, worn cylinder pin, damaged hose, loose fitting, low fluid, contaminated fluid, pump wear, pressure valve issues, manual bypass leakage, arm binding, or incorrect counterweight balance.
Do not assume the manifold assembly is the failed part based only on drifting or poor stopping behavior. Confirm the hydraulic circuit and valve function before ordering. A contaminated hydraulic system can damage a replacement manifold or valve quickly if the fluid, hoses, fittings, and pump pack are not inspected during service.
Before Ordering, Confirm
- The required part number is MX000146.
- The operator is a HySecurity StrongArm 14F, StrongArm 20, StrongArm 28, or StrongArmDOT 28 application where the parts diagram lists MX000146.
- The operator is not a StrongArm 36 / HTG 320-8 requiring MX000235 unless the current parts diagram confirms otherwise.
- The repair requires the brake manifold assembly, not only the MX000234 brake valve or another individual hydraulic valve.
- The pump pack manifold layout, hose routing, fittings, and valve arrangement match the original installation.
- The hydraulic issue is not caused by low fluid, contaminated fluid, leaking hoses, fittings, cylinder bypass, pump pack wear, manual bypass leakage, or incorrect arm balance.
- The package includes the expected manifold assembly and any required valves, fittings, seals, or hardware, or those related parts are ordered separately.
- The operator has not been modified with a non-standard pump pack, manifold, or hydraulic valve arrangement.
Installation and Service Notes
- Secure the barrier arm before servicing hydraulic manifold or pump pack components.
- Do not work under an unsupported arm or counterweight-loaded arm assembly.
- Disconnect and secure operator power before servicing the pump pack area.
- Relieve hydraulic load according to the manufacturer's service procedure before opening hydraulic connections.
- Keep hydraulic ports, hoses, fittings, and manifold openings clean during service.
- Do not mix up hose routing, valve locations, or fittings during reassembly.
- After service, check for leaks, proper arm hold, smooth travel, correct stopping behavior, proper limit operation, and all required safety devices.
Professional Advisory
StrongArm brake manifold service should be handled by a qualified gate technician when the repair involves hydraulic pressure, pump pack diagnosis, heavy barrier arms, counterweights, brake valve operation, pressure-control valves, hose routing, fluid contamination, or unknown prior modifications. Do not bypass limit controls, stop circuits, kill switches, hydraulic protections, controller protections, access control safety inputs, photo eyes, safety edges, or any required safety devices to keep the operator running.
Product Questions & Answers
What is HySecurity MX000146?
HySecurity MX000146 is a brake manifold assembly / brake manifold kit for select HySecurity StrongArm barrier gate operator applications.
What StrongArm models use MX000146?
HySecurity parts documentation lists MX000146 for StrongArm 14F, StrongArm 20, StrongArm 28 and StrongArmDOT 28 applications. Use it only where the operator parts diagram confirms this part number.
No, not based on the standard StrongArm parts documentation. StrongArm 36 / HTG 320-8 is listed with a different brake manifold kit, MX000235. Verify the current parts diagram before ordering.
Is MX000146 the same as the brake valve?
No. MX000146 is the brake manifold assembly or kit. The brake valve is a separate related hydraulic valve commonly listed as MX000234.
Can a brake manifold problem cause the arm to drift or drop?
It may be involved, but arm drift or dropping can also be caused by the brake valve, cylinder bypass, hose leaks, check valves, low fluid, contaminated fluid, pump pack wear, manual bypass leakage, or incorrect arm balance.
What should be checked before replacing this brake manifold?
Check the brake valve, check valves, manual bypass valve, relief valve, hydraulic cylinder, hoses, fittings, fluid condition, pump pack, cylinder linkage, and arm balance before replacing only the manifold assembly.
Should a technician replace this brake manifold assembly?
Yes. A qualified gate technician is recommended because this repair can involve hydraulic pressure, pump pack components, heavy barrier arms, braking behavior, hose routing, and safety-critical operator operation.
