The Brake Booster 427779 / 93741050 is a high-performance braking system component produced by SOFT, specially tailored for Chevrolet Matiz (X-TYPE) vehicles. As a core part of the brake system, it amplifies the force applied to the brake pedal, reducing the effort required by the driver to achieve effective braking. This brake booster uses vacuum-assisted technology to enhance brake response speed, ensuring shorter braking distances and safer driving experiences. Manufactured to strict quality standards, it is a perfect replacement for worn or damaged original brake boosters, restoring your vehicle’s braking performance to its optimal state.
This brake booster serves as a bridge between the brake pedal and the master cylinder. It utilizes engine vacuum to multiply the pedal force, enabling the brake system to generate sufficient hydraulic pressure quickly. This ensures that the brakes engage promptly when needed, which is crucial for avoiding potential driving hazards.

The 427779 / 93741050 brake booster significantly boosts braking force, allowing the vehicle to stop faster even at high speeds. It reduces the driver’s pedal pressure, making braking operations more effortless, especially during emergency braking scenarios, thus improving overall driving safety.
Constructed with robust materials, this brake booster can withstand long-term use under various driving conditions, including frequent braking and extreme temperature changes. It maintains stable performance without failure, avoiding brake system malfunctions caused by booster wear.
Designed as a direct replacement for the original part of Chevrolet Matiz (X-TYPE), this brake booster requires no additional adjustments or modifications. It simplifies the replacement process, saves installation time, and ensures consistent performance with the vehicle’s original brake system.
This brake booster is exclusively engineered for the Chevrolet Matiz (X-TYPE). It is manufactured to match the vehicle’s brake system specifications, ensuring seamless integration and reliable performance.

The brake booster uses the vacuum generated by the engine to amplify the force applied to the brake pedal. When you press the pedal, the booster uses vacuum pressure to push the master cylinder piston, increasing the hydraulic pressure in the brake lines and improving braking efficiency.
Common signs include a hard brake pedal, longer braking distances, or a hissing sound when pressing the pedal. If you notice any of these symptoms, it is recommended to replace the brake booster promptly.
No, this product is specifically designed for Chevrolet Matiz (X-TYPE). Installing it on other models may cause compatibility issues and affect braking performance.
