What is indicated by the presence of gaps when inspecting brake linings?

The presence of gaps when inspecting brake linings is a clear indication of excessive wear. Under normal operating conditions, brake linings should fit snugly without noticeable spaces. Gaps signify that the material has been worn down more than what is acceptable, which can lead to decreased braking performance and increased risk of failure. This wear could result from prolonged use or inadequate maintenance of the braking system.

Recognizing this wear is crucial for safety, as it directly impacts the vehicle's ability to stop effectively. Therefore, identifying gaps during inspection is an important part of routine maintenance that ensures the braking system is functioning as intended and can prevent accidents caused by brake failure. Replacing or adjusting worn brake linings is essential for maintaining safe operation.
