Abstract
A brake system for the doors of excavator buckets which increases the braking force of the doors, allowing the use of heavier caps with more shield, increasing the durability and reliability, cushioning the blows of the door against the frame of the bucket and decreasing the likelihood that the whole system is deregulated at the same time.
