This document describes the final design of a brake system. It has interchangeable brake pads, a unique tension spring design to keep the brake arms in tension and restrict their movement, an easy to access mechanism through clip-in housing connectors, an alarming warning design that complies with safety protocols, and a high strength hook to withstand loads on the chain.

1. Final Design
Key features
 Interchangeable brake pads to offer a convenient way of replacing worn ceramic pads.
 Unique tension spring design which keeps the brake arms in tension and constricts their
movement to a single plane.
 Easy access to mechanism using HDPE housing clip-in housing connectors.
 Alarming ‘warning’ design which complies with construction safety protocols.
 High strength hook to withstand the loads on the chain.
