Product Description
Air Brake Booster MC828265 For Mitsubishi Fuso FV515 8DC9 – Heavy Duty Truck Brake Servo
Product Overview
The air brake booster (brake air servo / air master brake booster) with OEM number MC828265 is a direct replacement for the factory-installed pneumatic brake assist unit on Mitsubishi Fuso heavy-duty trucks, specifically the FV515 chassis equipped with the legendary 8DC9 V8 diesel engine.
The 8DC9 is a 16.0-liter naturally aspirated V8 diesel engine producing approximately 380 horsepower. It is one of Mitsubishi Fuso's most powerful and durable engine platforms, found in the Super Great series of heavy-duty trucks, including dump trucks and concrete mixers.
The MC828265 booster is a pneumatic (air-over-hydraulic) unit. When the driver presses the brake pedal, the booster uses compressed air from the vehicle's air system to amplify the force applied to the master cylinder, significantly reducing pedal effort.

Installation & Maintenance
⚠️ IMPORTANT: The air brake system operates under high pressure (typically 120-145 psi / 8-10 bar). Professional installation by a qualified mechanic is strongly recommended. Incorrect installation can lead to brake failure.
When to replace this brake booster (symptoms):
| Symptom | Diagnosis |
|---|---|
| Hard or heavy brake pedal | Loss of air assist - booster diaphragm or valve failure |
| Increased stopping distance | Reduced braking force - replace booster immediately |
| Hissing noise from booster area | Air leak - diaphragm or seal failure |
| Brake pedal does not return to normal position | Internal mechanical fault - replace booster |
Critical installation notes:
- Depressurise the air system completely before removing the old booster
