Jlab Export is a leading Model of Air Brake System (Working) Manufacturer,and suppliers in India
This air brake model works on compressed air from its own compressor, driven by a fractional horsepower, single phase 220/230 V AC motor. The foot brake and hand brake are functional. Two complete front wheel assemblies, without axle, carry the brakes, and their drums are sectioned so students can watch the brake shoes move. Everything is mounted on a sturdy iron frame.

What Happens When the Pedal Is Pressed
With the motor running, the compressor charges the air tank, and the unloader valve takes the compressor off load once the tank is at working pressure. Pressing the pedal opens the foot valve. Air flows to the booster, which pushes the brake linkage and spreads the shoes against the drum.
Letting the pedal up exhausts the air with a hiss, and the return springs pull the shoes away from the drum. On the sectioned drums both movements can be seen. The hand brake can be applied as well, so students see the brake held on without the pedal.
Air Brake Practicals in the Workshop
Students start the motor, watch the air tank charge and listen for the unloader taking the compressor off load. They then press the foot valve in short and long strokes and compare how firmly the shoes grip the drum each time.
Before the working demonstration, the teacher can show the same parts cut open on the Model of Air Brake System. The Air Brake Actual Working, with its air tank, air booster and mechanically operated lever, gives a second unit for comparing how the shoes are applied.
Frequently Asked Questions
What power supply does the working air brake model need?
A single phase 220/230 V AC supply for the fractional horsepower motor that drives the compressor. The motor and compressor make the compressed air the model runs on, so no workshop air line is needed.
Why is the brake drum sectioned?
A cut-away drum lets students see the brake shoes expand against the drum when air reaches the booster, and pull back when the foot valve releases it. In a closed drum this movement is hidden.
Are the foot brake and hand brake both working?
Yes. Both are functional, so students can apply the brakes from the pedal and from the hand brake and compare the two actions on the sectioned drums.
How is an air brake system checked for leaks?
On a vehicle, charge the system, stop the engine and watch the air pressure gauge with the brakes released, then with the foot brake held on. A pressure that falls quickly points to a leak. On this model, listen for hissing and brush soap solution on the joints and valves.
Why do air brakes hiss when they are released?
When the pedal is let up, the foot valve vents the air in the boosters to atmosphere. That rush of escaping air is the hiss, and it shows the brakes have come off.
