Hi,

I've had my CBR125 for about a week now and ever since I bought it a week ago, I have noticed that when I use the back brake I hear a fairly loud squeeking sound. Its not like the kind of high pitch sound you hear when a car brake has worn down, it sounds more like a push bike wheel when its full of muck or something. It has gradually got a lot louder and more common over the last few days and I need to try and find out how to get rid of it. I'm going to try cleaning it but it was spotless when I bought it and like i said it did it a bit then so I dont think it could be dirt... I'll see if its the same after cleaning it but has anyone got any other ideas what it could be? Someone else who has a CBR125 told me that theirs does the exact same thing even straight after they have cleaned it etc. Oh and mine is only 4 months old with 1500 mile on the clock so its not like anything should be worn down on it.

Thanks!
Chris

 

use some fine grit sandpaper, scuff the surfaces of the rotor, and the pads, VERY LIGHTLY on the pads to deglaze them. this is usually a source of noise. just like on cars.
