⚙️ Complete Iveco Daily Mastervac – Restored Power Brake System, Ready to Install
🔧 What is this part used for?
The mastervac, or brake booster, is the central component of the power braking system. Mounted between the brake pedal and the master cylinder, it amplifies the force applied by the driver using engine vacuum, enabling effective braking without excessive effort. On the Iveco Daily, it is a critical active safety component: a faulty mastervac immediately results in a hard brake pedal, increased stopping distance, and loss of vehicle control, especially when the vehicle is loaded.
This MasterVac is offered brand new as a complete unit: it integrates the brake booster, master cylinder, and brake fluid reservoir into a single pre-assembled unit, ready to install without modification. It is an exact replacement for the original MasterVac assembly on Iveco Daily 35C and 35S models starting with MY2016 (MY2016, MY2019, MY2022, and MY2024), equipped with 2.3- and 3.0-liter engines (F1A, F1C).

✅ Why replace this part?
✅ A faulty Mastervac makes the brake pedal hard and difficult to depress, dangerously increasing stopping distance, especially during emergency braking while carrying a load.
✅ An internal leak in the master cylinder causes a gradual drop in hydraulic pressure in the system, with the risk of total loss of braking on one axle.
✅ Replacing it with a complete new assembly (servo, master cylinder, and reservoir) fully restores the original braking efficiency and ensures the vehicle can be put back into service immediately.
✅ Signs of Wear / Failure / Replacement
The first signs of a failing Mastervac on an Iveco Daily are a brake pedal that gradually becomes stiffer and requires increasing effort to achieve the same braking performance. A whistling or hissing sound may also be heard when the pedal is pressed, indicating a punctured internal diaphragm. An abnormal and repeated drop in the brake fluid level in the reservoir, with no visible leaks in the system, may indicate an internal failure of the master cylinder. Finally, a brake fluid level warning light combined with a soft pedal should prompt an immediate diagnosis of the entire MasterVac unit.
✅ Installation Tips
Before performing any work, disconnect the battery and completely bleed the hydraulic brake system. The complete assembly is installed as a direct replacement for the original unit, without any modifications to the system or mounts. After installation, fill the reservoir with the brake fluid recommended by the manufacturer and bleed the entire system, starting with the farthest brake. Check all hydraulic connections for leaks before putting the system back into service. Installation by a qualified mechanic is strongly recommended for this active safety component.
✅ Technical advice from RAXOR Parts
When replacing the Mastervac, always check the condition of the vacuum hose that supplies the power brake booster: a cracked or softened hose will eliminate brake assist even with a new Mastervac. If only the master cylinder is faulty and the brake booster is not affected, it can also be ordered separately.
