this is my first time owning a set of Hayes Nine hydraulic disc brake on my Marin. Everytime I brake with the front brake it squeaks when I squeeze it hard, but when I squeeze is soft it won't make the noise only when I'm close to a complete stop it would squeak again. I had thess brakes since like may, I dont think I need new brake pads already since I use the back a lot more than the front and the rear HASN'T made once noise whatsoever! Please give me some advice! thank you!
