Well, this wil be about the fifteenth problem woth my Hayes HFX-9's. I didn't upgrade yet but listen to my problem. I was riding around a local neighborhood with my friend and my rear disc started vibrating like mad like so much my back wheel was acting weird and I could feel it through my frame. So I squeeze the lever a little more and all I heard was squirt and I look behind and all of this brake fluid or hydraulic fluid is squirting everywhere. All over my pads disc hub, back of my body etc. My hose obviously broke. So what will I have to replace since the fluid got on everyhing, I think I need to replace the hoses, pads and disc. am I correct if I do replace the pads, which ones should I get? I will just get the same disc though.
