Power Brake for Electric Vehicle

 Now VBS has become the best solution for many EV manufactures around the world, and all consider it a extra quite one with perfect performance in improving the brake efficiency of electric vehicles.

The original vehicle was equipped with a power brake booster which was vacuum powered. This vacuum came from the intake manifold of the combustion engine. For similar driving characteristics and safety this vacuum must be supplied by another source. Vacuum pump replaces the vacuum provided by the internal combustion engine.

Vacuum switch will turn on the pump when vacuum falls below the sDet value. The kit comes with all the components needed for a complete vacuum assist solution. This includes an ultra-quiet pump, automatic shutoff switch, relay, fuse, and tubing. Most pumps used for vacuum assist produce a noisy drone that diminishes the elegance of quiet electric vehicle operation

The main function of VBS:

1. provide the electric vehicles with the vacuum assistance as the engine of the automobiles does
2. work as the brake system
3. shorten the braking distance to 18.9 meters from 60 to 0 m.p.h
4. Improve the vacuum braking force and the horsepower
Special Features:
1. Electric pump VBS
2. 100% braking efficiency consistently
3. Easy-to-fit, no modification of the original design is required
4. could work with or without ABS:
with ABS: make the brake safer
without ABS: work as the brake system
5. an apparent notification- handbrake light
6. the voltage and amp of VBS could be modified to suit for various standards
7. low noise, extra quite pump

Working Principle Of A Traditional Brake System

The traditional brake system is made up of the vacuum booster and the high pressure circuit. When the driver steps on the brake pedal, the pedal pushes on the push rod of the brake fluid’s piston inside the vacuum booster, and it will in turn press the master cylinder’s piston to force the brake fluid into the ABS system through the metal pipework. Then the ABS system will distribute the brake fluid to the brake calipers and press on the brake discs to make the brakes operate.

Innovative Concepts Of VBS

1.Equip the sensor of the vacuum degree of the booster to the brake system.

2.When the vacuum degree of the booster is under standard, the vacuum pump will start up automatically.

3.Replenish the vacuum degree of the booster immediately to make the brake system keep on working normally.

4.To maintain the brake system within the original efficiency.

5.To efficiently avoid the dangerous of the brake caused by the vacuum deficiency of the booster, and ensure your life safety.

Main Functions Of VBS
1.To produce vacuum by means of an electric pump. This should provide continuous and stable vacuum assistance to the brake booster. If the engine malfunctions, the vacuum brake system still keeps on working.

2.When the vacuum degree of the booster is not sufficient, it will detect it automatically and replenish it to the standard value. And it will provide continuous and stable assistance to the brake pedal and achieve the best brake effect.

3.It will notify the driver by means of the handbrake lamp when the VBS operates.

4.It firms a stand-alone system, so modification of the original design is not needed.

5.It should cooperate with the existing brake system to increase the overall braking efficiency.

6.Make it unnecessary to quip the vehicle with a supplementary vacuum reservoir.

Suitable For
1.All style with 12V/24V vacuum booster to all brands

2.Medium-sized bus (22 seats)

3.Medium-sized truck

4.Electric vehicles/ Hybrids/ Gas Cars/ Solar Sars


YT STABLE is an enterprise based on patent product development:

YT STABLE was founded in 2005, focusing on the field of vacuum brake boosters and patent development of vehicles. Guided by the chairman, Wu Sun Hsieh, YT STABLE has been devoted to the development of brake system on automobiles since 1996. We focus on the development of advancing the security appliance of vacuum brake booster and the products we produced not only gain the affirmation of manufacturers, but also be granted many patents. After tries of YT STABLE research and development team, we gained the patent certificate in 2004. And to expand the marketing network and build up proper supplementary measures, the company implements the comprhensive quality control. We also establish ISO standardization to prepare to enter the export market.
