Tension Spring / Spring Cam End Big
Its large, high-tension design provides the necessary force to counteract the expansion caused by the brake cam, maintaining proper brake shoe alignment and preventing drag. Manufactured from heat-treated spring steel, the component delivers excellent strength, elasticity, and resistance to fatigue and high temperatures. Its durable construction ensures long life even under continuous braking cycles typical of commercial vehicles.
By ensuring proper brake shoe return, the spring enhances braking efficiency, reduces lining wear, and prevents overheating caused by residual drag.
Key Features
- Heavy-duty tension spring for brake cam end
- Ensures proper brake shoe return and prevents drag
- Made from high-strength, heat-treated spring steel
- Resists fatigue, deformation, and high temperatures
- Enhances braking efficiency and extends brake component life

Process Steps
- Remove brake drum and inspect the brake shoe and hardware.
- Detach the old tension spring from the cam end and brake shoe.
- Inspect hooks and anchor points for wear or damage.
- Install the new tension spring securely onto the designated mounting points.
- Verify proper tension and correct brake shoe return movement.
- Reassemble the drum and test for smooth, drag-free rotation.
FAQ
What does the cam-end tension spring do?
It pulls the brake shoe back after braking, preventing drag and maintaining proper shoe alignment.
When should this spring be replaced?
Replace when it becomes weak, stretched, broken, or during complete brake overhauls.
