Noisy Brakes

[Linneke]

I've ridden my new bike for about 20-25 hours since getting it just over a week ago. The Avid Juicy 7 brakes have been squeaking and screeching for the past five rides, even though I've cleaned the rotors with alcohol twice and taken it into the shop for the first tweaking. The guys at the shop didn't see any problems and I've taken their suggestion of doing lots of high speed stops to burn anything off the pads, but I'm still hearing a lot of noise. Should I be concerned? Can I do anything to stop this or will it go away over time?

What kinda rotor do you have? I hear that the old rotors made lots of noise. These (http://www.jensonusa.com/store/product/BR707Z02-Avid+Rotor+-+Clean+Sweep.aspx) are the newer ones that are suppose to be better.

I also recently got some 7s. Then made a bit of a noise for a while and then it got better, but is still makes a gobbling sound when they get wet. I'd say just try to go with them for another few weeks. I also read on mtbr that different pads make improvements. So, if it really bugs you try a different type of pad. They still stop good right?

I have the new rotors, but I will keep riding and see if they get better. They definitely still stop the bike quite well - it just sucks to be terrifying birds and squirrels with my screeching.

I have several sets of Juicys on various bikes. The stock pads are sorta noisy, especially when they are wet. I find that the EBC gold pads work best and are a bit quieter (they make quiet grinding noises rather than squeals). Note that being a sintered pad, they heat up faster, which can be a problem on long downhills (especially with smaller rotors).

Or just get used to it. The only thing that stops me quicker than Juicys is running into a tree, so I forgive them some noise. ;)

Where does the noise come from? If it's vibration between the pad and caliper piston, couldn't you use some automotive disc brake quieting goo? It's a high-temp lube that gets applied on the back of the pad and can work miracles on some noisy car brakes.

Get use to it! Mine come and go. Somedays they are perfect!
