    XT pads rattling - solutions?

    Got a nice brand new bike, everything is quiet, apart from the pads on my new XT brakes. The pin is tight, I tried bending the spring out a little to increase the tension, but no difference. Really annoying that it's the only thing on the bike making a noise - any potential solutions? Seems perhaps changing pads is one, to get rid of the cooling fins.

    Do nothing. Fairly quickly the brake dust and dirt will build up around the pads and dampen their movement.

    Also, pretty soon other parts of the bike will start rattling much more than your brake pads ;0)

    It is true, that's why I said it! You can attain similar results, but not as good, by smearing copper grease on the backs of the pads but it's a little more risky as it might get on the disks. Just a touch is all you need.

    Yeah, just ride it. As long as you are riding where there is a bit of dirt and moisture it should shut up.

    Same Problem over here! What's the deal? I'm not sure i'm super impressed with the new XT 4 piston brakes that I just replaced my Guides with, my pads rattle like crazy and my contact point changes when brakes heat up or rattle...I have tried bleeding brakes to fix the contact point issue but it still happens! I have new non-finned pads not he way to see if that fixes the rattling issue, fingers crossed!

    I picked up a tip somewhere - used the black rubber bands that hold a tube wrapped up and wrapped it around the fins. Worked a treat and did not impact braking (plus you can't see the black on black) - I now have plenty of dust and grime in them so maybe they'd now be quiet without them.

    Unlikely to make any difference.

    try this bleed method, it fixed the same issue I was having.

    Rattling pads (quasi normal) can be corrected by bleeding?

    I'm guessing it improves small bump compliance too?

    Nope bleeding solves the contact point changing during a ride. Adding a flux capacitor to the air side of the fork is amazing for small bump.

    As others have said the rattling goes away once it gets dirty or you just get use to it and think it went away.

    Flux capacitor on the air side huh?

    Never tried that because I have always found some level of success by tweaking the Girdle Spring counterclockwise and gently adjusting the Kanutter Valve until I feel a slight resistance, then back it off a bit.
