Vacuum Brake Booster | Power Braking System | Construction and Working in Hindi

Vacuum brake is one of the most popular power braking system which can be equipped with both disc and drum brake. When we required this external device the brake is known as power brake. There are many other power brakes available like hydraulic brake, air brake etc. This braking system have minimum lag time compare to other braking system due to which it is mostly used in trains.

Construction and Components of vacuum booster brake :
1. Servo Cylinder:
It is a simple piston cylinder arrangement in which one side of the piston rod is connected with the brake shoe. The piston is subjected to vacuum at both side in brake released position. When the brake is applied one side of the piston is exposed to atmosphere due to which a immediate braking force applied to piston which push the brake shoe.
2. Vacuum Reservoir:
When the engine is in running position the vacuum in servo cylinder is created by inlet manifold but when the engine is stopped the vacuum reservoir is used to create vacuum in servo cylinder.
3. Control Unit:
The control unit is used to apply brake. It is also a piston cylinder arrangement in which the upper valve is used to connect atmosphere to the servo cylinder and the lower valve is used to connect vacuum reservoir to servo cylinder. When the brake is applied the upper valve is in open position while the lower one is in closed position.
4. NRV:
NRV which mean non return valve is used to connect servo cylinder to inlet manifold which allow only one sided flow of air from servo cylinder to inlet manifold.
5. Master Cylinder:
Master cylinder is same as used in hydraulic brake which is used to operate the control unit.
Working of vacuum booster brake :
When the brake is in release position both side to servo cylinder is exposed to vacuum. The upper valve of the control unit is in closed position while the lower valve is in open position.
Now when the driver press the brake pedal, the master cylinder comes into action which pushes the piston of control unit in upward direction. This movement of piston opens the upper valve of control unit and simultaneously closes the lower one.
The opening of upper valve allows entering air into the servo cylinder left side through control unit. This will create a differential pressure in servo unit. This will pushes the servo piston at right side thus applied brake.
This arrangement of vacuum booster considerably reduces the effort applied by the driver and whole braking force is applied by the vacuum.

Sir ek baar AIR- HYDRAULIC BREAK system or bata dete

[@manvaindermohansingh1429]

Mere pass maruti Zen lxi 2004 model hai.
Break lagane par aisa mehsoos hota hai ki break theek se nahi lag rahe. Matlab break pedal par jyada jor lagana padta hai. Jabki break pedal par halke se press karne par break lag jaane Chahiye.
Break shoes bhi change karwa liye.
Mechanic jab try leta hai toh woh jor se break lagata hai aur gadi ruk jaati hai. Aur woh kehta hai ki breaks theek hain.
Lekin aaram se break lagne chahiye.
Aap kya suggest karte ho

भाई जी गुडमोर्निंग। मेरे पास आल्टो 800 है । एक दिन में 4 बार ब्रेक नही लगा तो मैं गाड़ी बन्द किया और मेकेनिक को दिखया मेकेनिक देखने के बाद बोला की ब्रेक तो सही है। उसने 10 बार जांच किया। फिर मैं अपने घर 10 किलोमीटर कार चला के लाया।ब्रेक की समस्या नही हुई। अगले दिन मैं एक दूसरे मेकेनिक के पास ले गया उसने 20 किलामीटर कार चला कि देखा एक बार भी ब्रेक का प्रॉब्लम नही आया उसने ब्रेक के सभी पार्ट चेक किया वो भी सही मिला। उसको मैं जबरदस्ती और भी ब्रेक ऑयल डलवा दिया बोलकर। फिर मैं उसको बोलै की बूस्टर और मास्टर सिलिंडर चेंज कर दो क्योकि मैं रिस्क नही लेना चाहता।तो उसने बोलै की क्यो पैसे बर्बाद कर रहे हो अगर प्रॉब्लम आनी होती तो 20 किलोमीटर चलने के बाद आ ही जाती । आपकी ब्रेक में कोई समस्या नही है।फिर कार को लेकर मैं घर आ गया।
प्लीज़ मुझे रिप्लाई जरूर करे मैं बहुत टेन्सन मैं हु।।
