Brake Wear Pin
Contents
When these pins (Two on each brake unit ie eight in total) become flush with brake housing, the brakes are ready for replacement. Bring to the attention of an engineer before dispatch.
Data suggests that the average wear rate is 0.001” per landing. This should mean that if a pin were only 0.01" proud, it should still be good for another 10 landings.
If observed downroute then it may be comforting to know that when any pin is flush, the associated brake unit still has enough capacity for an RTO - by law.
All of the information, photographs & schematics from this website and much more is now available in a 374 page printed book or in electronic format.
