Internally Expanding Mechanical Drum Brake System Manufacturer,Supplier and Exporter in India
Product Code : EL-IEL-10150
Jlab Export is a leading Internally Expanding Mechanical Drum Brake System Manufacturer,and suppliers in India
Internally Expanding Mechanical Drum Brake System (code EL-IEL-10150) is a demonstration model of a drum brake whose two shoes sit inside the drum, each pivoted on a pin. Force on the cam-lever turns the cam, which spreads the shoes outwards against the drum, and the braking action can be seen as it happens. This internally expanding brake model is produced by JLab in Ambala, India.

From Cam-Lever to Shoe Contact
Each shoe is pinned at one end, and the cam sits between the free ends. As the lever turns the cam, its profile pushes those ends apart, so each shoe swings about its pin and presses on the inner surface of the drum. Friction between shoes and drum then resists the drum’s rotation.
Cam Expansion and Hydraulic Expansion
This model expands the shoes mechanically. A hydraulic drum brake does the same job with a wheel cylinder whose pistons push the shoe ends apart under fluid pressure, while air-braked trucks and buses still turn a cam to spread their shoes, with an air chamber working the lever.
Drum and Disc Brake Units
- Vacuum Assisted Hydraulic Drum Brake — a sectioned unit with vacuum booster, master cylinder and wheel cylinder.
- Air Brake Actual Working — a sectioned full-size air brake with air tank and air booster.
- Mechanical Disc Brake Working Model — a lever-operated disc brake complete on its base.
