Feature:

  1. Improve braking force:
Hydraulic power brake booster converts hydraulic pressure into mechanical force through hydraulic power mechanism, thereby increasing braking force. This feature allows for longer braking response times and more effective reduction of braking distances.
  2. Stable:
The work of the hydraulic power brake booster has nothing to do with the state of the engine, whether the engine is running at high speed or idling, it can ensure the stability of the braking force.
  3. Independent operation:
No reliance on engine vacuum to ensure reliable braking.
 4. Direct replacement, easy installation.

Note:
  1.Without Master Cylinder！！！
  2.Professional Installation Is Highly Recommended.
  3.Even if your car is shown in the compatibility, pls also double check the fitment details and photos before ordering!
  4.Pay attention to protect the oil pipe thread from damage and prevent the brake fluid from flowing.
  5.When installing the vacuum booster, make sure that the liquid storage tank is upward after loading and can not be installed reversely.
  6.Check whether there is oil leakage at the connection between oil pipe and master pump.

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.
