My breaks are making noise
 
It seems that when i use my rear brake, the rotors, or pads make noise like squeek.

When the bike is rolling or moving, the front automatically makes braking squeeking noise.
Even when i dont use them, like when the bike is rolling forward.
And even when i do apply my front brakes, they squeek as well..

And the front and rear rotors look dirty.

I'll try to get pictures. ANdy hElp would be awesome.
Bike was never down by the way..

Probably have some glaze on the brakes. If you are a hard braker then this is common espescially on the rear brake because it is smaller and doesn't shed heat as well. It will wear off just don't ride your brakes too hard, and it will take time. I have glaze on mine after a trip to the track usually however many people even in every day riding can overheat the brakes. Some brake cleaner might help DO NOT USE A SQUEAK STOPPER. They ruin your brakes.

its normal....

Mine have a little squeak too. Try the brake cleaner but also see if you have a little sand between the rotor and pad.

I'm goign to try and use brake cleaner, and spray the rotors and pads, and wipe the rotors. I'll also try sanding paper on the rotors??

That I haven't heard of, I've seen scotchbrite on an air powered grinder used whil the wheel was spinning, but not sand paper. You may want to post this or search on this in the general tech section.

After riding for an additional 300 miles or so, the front brake/rotors still make metal scratching noise. I don't brake hard at all. its all @ at ease.

Im guess the front rotor and pads, or not properly assembled. or have been mis aligned causing them to rub when they roll.

Because i just met another cbr f4i rider 2005, and he rides with out noise, and had the bannana seat style, but that shoulnd't make a difference.

Thats my only problem that is frustrating me.

You've reported two things here, it seems to methat your brakepads have been progressively wearing out. Suggest you check / replace the padsif worn outbefore you damage the discs.

The F4i come with uber brakpads that iv' been told will never wear out, but the downside is they squeak sometimes... just ignore it you are fine

You sure? I understand if they squeak while i'm braking,
but they squeak and sound like two metals rubbing while i'm rolling and NOT braking.

if its a metal to metal grinding while you are rolling and not using the brakes then the disc/rotors could be warped

Sounds like the pads are worn to the backing plates and you've used them that way long enough to damage the rotor. I bet the backing plates are resting against the rotor surface. Sounds like you'll need new pads and rotors. I just hope the heat transfer hasn't hurt the caliper piston seals yet. I'd take the caliper off and at least look at the pads ASAP. If they're down to the metal plate making direct contact with your rotors you're going to need new ones. If you can do it yourself you'll save a lot of money...but if you aren't up for it get your bike to the dealer ASAP to take a look at it. You don't want to ride it this way...trust me.

I didn't think about it like that. Good Idea.
How hard is it to swap the Front Rotors?
I have a spare used, but seems fine, set of rotors i might swap out.

OOH NUTS! yeah where i can purchase new OEM brake pads at low cost?
I plan to do it myself to save money, on top of that, dont think i have money for new rotors, so might just replace the rotorswith the used spare i have.

Have you adjusted your front break lever closer to the grip? I done this and i guess went a little far and heard that grinding noise on a free roll. Rolled the adjuster out a couple turns and it was gone.

No i did not adjust the brake lever.

RE: My breaks are making noise
 
the brakes should make a very quiet noise when just rolling and not braking. disc brakes usually have slight contact with the rotors while not being used so it always makes a little bit of noise. but if they are squeaking and you have cleaned the rotors and made sure there is nothing in the pads, then i would say the first thing to check do is just buy some new pads. its cheaper than replacing a rotor and easier to replace. sometimes pads just start squeaking after a while, ive had it happen to me. just dont forget to put some disc brake adhesive between the back of the pad and the piston so that it doesnt start floating in the caliper.

RE: My breaks are making noise
 
its probally just some sand or something in the pads that is rubbing. i hear the ssame "squeak" while riding and i still have pad left.. and i have been riding stoppies and what not a bit more recently, so they still grab! ha
