Heli 3.5T Brake Master Cylinder: confirm the brake fault before ordering
1. Confirm the fault
Record pedal travel, whether pressure holds, where fluid is lost and whether the truck pulls to one side. A hydraulic leak and a mechanical brake-adjustment problem require different repairs.
2. Identify the exact part
Confirm the Heli model, serial number, part number 25595-40302A, mounting pattern, port position, pushrod length and left/right installation where applicable.
3. Inspect during service
Brake-fluid level and visible leaks should be checked during routine service. Replace contaminated fluid according to the truck maintenance schedule; inspect cylinders whenever pedal feel, stopping distance or wheel balance changes.
4. Choose the supply option
Use a genuine part when the truck revision or safety-critical dimensions cannot be verified reliably. A proven replacement can be economical for routine fleet repair only when bore, seals, ports, mounting and service history are confirmed.
Review related forklift brake parts or send the truck plate, old-part photos and quantity for checking.
Request brake-part verificationImportant brake master-cylinder reminder
Confirm the hydraulic circuit before replacing the master cylinder
Pedal travel or weak braking does not automatically identify the master cylinder as the cause. Confirm the truck model, cylinder reference, bore, reservoir and pushrod arrangement, mounting centres, outlet-port threads and brake-fluid specification.
Confirm the fault
Inspect pedal linkage and free play, fluid level, external leaks, wheel cylinders, pipes, hoses and brake adjustment. Internal bypass should be confirmed before ordering.
Identify the part
Use the complete part number, truck nameplate, overall photos and clear measurements of the mounting flange, pushrod and hydraulic ports.
Commission correctly
Bench-prime when required, use clean specified fluid, bleed the complete circuit and verify stable pedal pressure and balanced braking.
