front brake noise, not squeal, more like purr

[daron]

hello all,

So, thanks to the torque specs by dgyver and photos from Kerry, I just finished changing the front brake pads on the '06f.  I put on EBC FA231 as per info received here. 

However, I just took a little test ride and I'm hearing kind of a "purr" like noise when I apply the brakes.  It sounds almost like if you put a playing card in the spokes of a bicycle or in an ordinary house fan.  It's not really loud but I can hear it through a full face helment.  I'm too worried because it's not a squealing noise or a metal on metal noise.  The brakes feel fine by the way.  They stop well and have good response/feel.

Has anyone ever encountered this?  Should I be worried?  Perhaps, it'll go away with a little breaking in (no pun intended)...

Thanks,
Daron

My understanding is that the vents in the rotor will cause some noise from the air being trapped for a short time and popping when it's released...

Basically, if you have a vented rotor, you'll have a humming/fast popping noise when you brake...


But...   There could be some other concern that I don't know about.

ok,

That sounds reasonable.  I had a BMW once that made the same noise but I thought it was just because of the ABS system.

and seeing as how the GS doesn't have ABS, it made me wonder.

Thanks for the response

BTW, is that a Honda c70 in your photo?   The C90 Super Cub is still sold down here and you see them all the time with a mountain of miles on them.  I can't imagine riding a C90 for 30,000 miles but they're a dime a dozen down here.

no no, the GS has ABS... it just has "Self Modulated Stealth ABS"....


you'll never even know about it.

'68 Trail 90.     The first moto I ever road...
