Elevator Brake Maintenance & Durable Component Tips
In an elevator system, if the traction machine determines whether the elevator can run, then the brake determines whether it can stop safely, smoothly, and reliably.
Many maintenance engineers have experienced this situation: the elevator appears to operate normally, yet suddenly shows sliding, creeping, abnormal noise, or even trips into fault shutdown. After troubleshooting, the root cause is often not the control system, but the long-neglected condition of the elevator brake.
As an elevator and escalator spare parts supplier deeply involved in maintenance and modernization projects, A-FLY prefers to address this topic from real-world operating scenarios—explaining how elevator brakes should be maintained and how to select more durable brake components.
1. Why Do Many Elevator Brakes Fail Faster Than Expected?
An elevator brake is not a one-time action component. It operates during every start and stop cycle. However, in real projects, it often faces several practical issues:
Long-term high-frequency operation without systematic inspection
Brake clearance changes that are not adjusted in time
Worn brake linings that continue to be used
Aging coils and springs misdiagnosed as “control system issues”
As a result, the brake may not be completely failed—but it is no longer reliable.
2. Common Warning Signs of Elevator Brake Problems
Before a serious incident occurs, the brake usually gives early warning signals:
Noticeable impact or dragging sensation during stopping
Inaccurate leveling with occasional slight sliding
Metallic friction noise from the traction machine area
Abnormally high brake coil temperature
Brake performance approaching the limit during annual inspection
These symptoms indicate that the brake has entered a high-risk condition, and continued operation only amplifies potential hazards.
3. Practical Elevator Brake Maintenance Methods
1. Regularly Check Brake Clearance—Not “By Feel”
Brake gaps that are too large or too small will affect braking performance and must be adjusted according to actual operating conditions.
2. Pay Close Attention to Brake Lining Wear
Brake linings are typical consumable parts. Once surface hardening, thinning, or uneven wear is observed, replacement should be carried out promptly.
3. Monitor Aging of Brake Springs and Coils
Spring fatigue and coil magnetic force decay are common root causes of many “hidden elevator creeping” issues.
4. Keep the Brake Clean
Oil, grease, and dust contamination directly reduce friction coefficients and compromise braking reliability.
4. Why Durable Brake Components Matter More Than Low Prices
Saving costs on braking systems is often the most expensive mistake in the long run. High-quality elevator brake components typically offer:
Stable and consistent braking force
High-temperature and fatigue-resistant material structures
Longer adjustment and replacement intervals
Excellent compatibility with mainstream traction machines
This not only reduces failure rates but also significantly lowers long-term maintenance costs.
5. A-FLY’s Recommended Approach to Brake Component Selection
