Finally retired and building my project bike

[Johnwebley]

My 400 & 500 have the nylon type ring on the one static pad back.
I think Grahame is talking about the piston to pad contact being convex or concave.

Are you sure that is the correct fitment?

I understand it fits between piston and moving pad

TBH I can't remember now where that plastic washer went it's over a year ago now - my manual does not even show it as a part. I have it in my head that if it was on the static side otherwise it would sit inside the piston & serve no purpose.

There might have been a leaflet in the pad box someone here will have the right answer?

Goes on the back of the moving pad.

Goes on the back of the moving pad.

That makes sense in terms of anti-squeal function.

Updated:- A nagging doubt made me check my 500 front calliper - the nylon type washer can only  fit on the piston side as its a different shaped pad back to the fixed side.

Battery is in and not leaking as of yet.
Now working on fitting front indicators to the fairing, making brackets to fibreglass inside fairing

Indicators done.
Getting closer to starting the engine.  I’ve put a very small squirt of diesel and 2 stroke oil in the bores and turned the motor on the starter. Oil light went out after about three bursts.
