Sounds from brake drum

As well as the dust seal make sure the 14mm washer is there as well. #392 on the drawing below.

When attaching the brake arm onto the splined shaft make sure that it is fully on and there is no in/out movement on the shaft.  You need to squeeze it from both ends by hand before tightening up the nut.

Thanks for this Dave. The washer ( part # 90549121000 ) doesn't look like just any 14 mm washer, can't be had on cmsl or DSS, nor did google and ebay search help.  ::) I guess I'll have to improvise!

Looking at the limited images for this, it looks like a thin shim washer or just a skinny flat form washer. perhaps someone reading this that has one to hand cold get their calipers out and report back.

This any use?

Hi Dave
I've ordered one, we'll see what happens then!  8)

Just been  trying to find my spare brake plate but it might be hiding in the loft.

Honda part code beginning 905 is a non standard item so as you suspect a bit of fettling might be needed.

I suspect the washer goes into a recess together with the dust seal and is probably there to keep the dust seal in place and not get chewed up by the break wear indicator plate.  Don't think the absence is responsible for the noises heard, just means the dust seal may work its way out a bit and not do it's job long term.

Might be worth having the bike on the main stand and spin the wheel by hand while gently applying a little brake , is the noise kind of even all the way round one wheel rotation or just a tight spot in one place.

Regards
Dave.
