O ring on brake caliper pin.

[Ozzieflyer 15]

Hello all,

Does anyone know what the purpose of the o ring on the end of the brake pad calliper pin?

What is the reason for an o ring in this place?

It is on the front and rear caliper pin.

It's to stop the pin backing out under vibration.

Thanks Andy.

You are correct I was referring to number 10. 
Good to know. That makes sense. 
 

Thanks again.
