Front brakes sounding like an old school bus is a 640 adventure trademark! But seriously, lot's of threads on adventure rider about it as I recall. May have something to do with spoke tension possibly IIRC.
Is this your new front wheel, or the old one?

My 640 was the same, the guys at Z-Racing in L.A. recomended EBC organic pads to stop brake noise, so I picked up a set: Part # FA 181x front, #FA 208x rear. I'm running them now and my brakes have never been so quiet, I have run them for about 2000 km so far.

I wore the noisy set out first before switching, like you I figured to get my $s worth out of the old ones and put up with a little bit of squeely embarassment at times. What year is your 640? I had my 03 rewheeled just before Christmas, nice replacement they give you, I never had any problems with the old one but others have. Some of the wheels failed, mostly spoke breakage and if at hwy speed could make for a dangerous situation.

i have since replaced all my spokes (both sets of wheels) with aftermarket ones... none have broken in 7000km, and the brake no longer squeals.
if you want to know more about the spoke thing do a search. i actually had a couple analyzed in an electron microscope. the pics are here somewhere.

I think you're right. My front brake's been squawlin' like a spoiled kid since I got the bike. Several days ago I realized it wasn't squealing any more. I was checking the air in the front tire a while later and found a broken spoke.

There ya go, enjoy!:tup:

I hope Loaded theory isn't totally fact because prior to renewal my back brake had it's noisy moments, in fact it was the back brake noise I was mostly inquiring about at Z Racing. Anyways, so far so good with the new pads.

Hi,
I'm not sure if I'm suggesting the obvious but if you haven't tried it yet, try SIL-GLYDE BRAKE LUBRICANT or similar stuff. I couple of bucks at good old CT.
Lubricate caliper slides and apply to all metal to metal contact points on pads and pistons.
My KLR squealed like a pig when I switched to Galfer pads. SYL-GLYDE applied every now and then has virtually eliminated the probem.

Once you get use to the vibration, you need to focus on getting use to the brake noise. :tup:
Once you're use to the abovecontact us again and we will let you know what's next......:dr:
......oil does not work on them either....:tup::tup::tup:
seriously, try a bit of gasket paper on the back of the pads on the "upside".....worked for me.
