Product Details
Brake Master Cylinder with Booster
,3540010LD040 for JAC N56 N75
,OEM Fit JAC Spare Parts
The OEM Brake Master Cylinder with Vacuum Booster, part number 3540010LD040, is a verified direct-fit brake system assembly for JAC N56, N75, N80, and N120 light trucks, and also cross-references to KAMAZ Kompas-5 applications. This matched assembly converts driver pedal force into hydraulic pressure while the vacuum booster multiplies that force, delivering reliable braking performance with reduced pedal effort.
- OEM Cross-Reference Verified: Replaces 3540010LD040 and cross-references to MOVELEX 3540010LD040MX and IZUMI equivalents.
- Fitment Confirmation: Confirmed for JAC N56 / N75 / N80 / N120 and KAMAZ Kompas-5 applications.
- Pre-Delivery Function Test: Each assembly undergoes a pushrod travel check and booster vacuum hold verification before packing, per in-house QC records (standard: 100% inspection before shipment).
- Complete Assembly: Master cylinder and vacuum booster are supplied as a matched unit, eliminating the need to source components separately.
- Brake pedal feels spongy or sinks to the floor under steady pressure.
- Pedal requires excessive force to stop the vehicle (booster failure).
- Brake fluid leaks visible at the master cylinder body or reservoir seals.
- Braking performance is uneven, or the vehicle pulls to one side under braking.
- Hissing noise from the booster area when pressing the brake pedal.

HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily oriented toward ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. Both "short" and "long" pushrod variants exist within the MC828264 family.
Always provide the VIN / chassis number for verification. Do not rely solely on cross-reference numbers.
| QC Item | Verification Method |
|---|---|
| Pushrod travel | Measurement against OEM specification |
| Booster vacuum hold | Vacuum applied and monitored for pressure loss |
| Master cylinder bore integrity | Visual and dimensional check |
| Reservoir seal seat | Visual inspection for scratches or deformation |
| Assembly leak test | Pressure hold check at ports and seals |
The brake system is safety-critical. Professional installation is strongly recommended. Brake fluid is corrosive and flammable. Bleed the entire brake system after installation.
- 1Disconnect the battery negative terminal. Remove the old assembly — cap the brake lines to prevent fluid loss and contamination.
- 2Inspect brake lines and fittings for corrosion; replace if necessary.
- 3Install the new assembly; tighten mounting nuts to the specified torque (consult workshop manual).
- 4Reconnect brake lines; fill the reservoir with the specified brake fluid.
- 5Bleed the system: Bleed at all four wheels in the correct sequence (typically RR, LR, RF, LF) until bubble-free fluid emerges.
- 6Function test: Verify firm pedal feel and check for leaks at all connections before road testing.
- Inspect brake fluid level and condition every 10,000 km.
- Replace brake fluid per the manufacturer interval (typically every 2 years).
- Check the booster vacuum hose for cracks or loose connections annually.
- If pedal feel changes or braking performance degrades, inspect immediately — do not delay.
- Neutral carton or customer-specified packaging (heavy-duty protection for brake components).
- Suitable for wholesalers, repair shops, and fleet maintenance.
