  Item Type: Hydro-Boost Power Brake Booster

Feature:

1.Improve braking force 
  Hydraulic booster brake booster converts hydraulic pressure into mechanical force through a hydraulic booster mechanism, thereby increasing the braking force. This function makes the braking response time longer and reduces the braking distance more effectively.
2. Stable 
  The hydraulic power brake booster operates independently of the state of the engine, ensuring stable braking force regardless of whether the engine is running at high speed or idling.

Note:

  * It comes with Hydro-Boost.
  * Without Master Cylinder.

About Power Brake Booster:
     Also known as a vacuum booster, it is a device used in vehicles. It works with the brake pedal and master cylinder to improve braking performance and reduce the effort required to apply braking. The working principle of the power brake booster is vacuum assist. When the driver applies pressure to the brake pedal, a valve in the booster opens, allowing the vacuum of the engine to enter the booster chamber. This creates a pressure difference that helps with braking.

How to choose the brake booster?
  1.Compare the appearance of your car's original brake booster with the picture of our product.
  2.Make sure your car is on the compatibility list.
  3.Compare OEM numbers.
