brake question

OK. I am now riding a CBR954RR. Here is the problem....

When I got the bike, the front brakes were making a weird buzzing noise. It sounds like locust swarming. I changed the pads. It is still making the same sound, but not as loud. They grab fine (great, in fact), but they sound odd. This is the 1st bike I have ever had that makes such a noise. I have never owned a Honda, though.

Any suggestions?

Could be the fallopian tubing is old. try replacing it with steel braided ones and it should fix your problem!

Your rotors have holes drilled in them - called Cross drilled rotors. As the pads sweep over the holes in the rotor, the air being trapped and expanded by the heat created by the braking forces casues the noise that you are hearing. It is a normal sound.

If what he means is that steel-braided brake lines will fix your 'problem', then that would be incorrect.

Interesting. I've never heard that sound on my cross drilled rotors.

Like I said, everything WORKS fine. I have never heard it on any of my other bikes. I am not stressing over it, I just wanted to know if it were normal or if there was something I should be checking.

I'm liking the bike so far, but it just doesnt match up to the ZX10R in the power department. Handling is much more progressive. I really like the chassis.

Take out your ear plugs (if you wear them) take off your helmet - get up to about 20-30 - mph - kill the engine (required on rattling suzuki's / JK couldn't resist) and most importantly bring your head down about 10 feet where a normal guys ears would be and gently apply brakes ( which will have no signifigant stopping effect @ our weight -) and you too will hear it.

a whirring noise is normal for a lot of bikes. My '02 gixxer 750 did it, and my '01 RSV did it. My '07 gixxer doesn't. If its a loud whirring noise, its perfectly normal.

I put new pads on my 06 GSXR 600 and I get that sound now. My brakes work great no problems but they make the same sound you are describing.
