MC828264 Air Brake Booster for Mitsubishi Fuso FV515 with 8DC9 V8 Engine – Heavy Duty Truck Brake Servo

The air brake booster (brake air servo/brake air master cylinder) with OEM number MC828264 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 8DC9 V8 diesel engine. This short-type brake booster multiplies the driver's braking force through compressed air to deliver reliable stopping power for heavy loads.

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. The FV515 is a 6x4 heavy-duty chassis designed for demanding applications with a gross vehicle weight rating exceeding 20 tonnes.
