# Industrial Specification: Brake Mechanism

## 1. Technical Definition
A mechanical or friction-based device integrated into a furniture caster to lock the wheel in place and prevent unwanted movement.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 N·m torque application, 0.1-0.8 mm engagement depth, 20-80 N engagement force**. Failure boundary: **Friction coefficient drops below 0.15 (static) or 0.08 (kinetic), engagement force exceeds 120 N causing plastic deformation, wear depth exceeds 1.2 mm**, Mechanism: **Adhesive wear (Archard's wear equation: V = K·W·L/H where K=3×10⁻⁵ for steel-polymer), thermal softening above 150°C (glass transition of polyamide components), stress concentration at fillet radii &lt;0.5 mm**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Contaminant accumulation (dust, oil) at friction interface | 8 | Brake slippage with 40% torque reduction | Sealed labyrinth design with IP54 rating, hydrophobic surface coating with contact angle &gt;110° |
| Repeated impact loading from caster drops &gt;25 mm height | 8 | Spring fatigue fracture at stress amplitude &gt;450 MPa | Shot-peened spring wire (Almen intensity 0.25 mmA), stress-relief annealing at 350°C for 2 hours |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: How does a furniture caster brake mechanism work?
**A**: The brake mechanism uses a lever or pedal to engage a brake pad or shoe against the caster wheel, creating friction that locks the wheel in place and prevents movement.

### Q: What materials are used in furniture brake mechanisms for durability?
**A**: Our brake mechanisms combine steel and zinc alloy for structural strength, with nylon and rubber components for smooth engagement and reliable friction-based locking.

### Q: Can these brake mechanisms be integrated into existing furniture casters?
**A**: Yes, these mechanisms are designed for integration with standard furniture casters during manufacturing, with components like engagement pins and springs ensuring proper installation and function.

## 6. Manufacturing Compliance
- ISO 15484:2008 (DISC BRAKES FOR ROAD VEHICLES)
