Couple of brake problems!

I've got two issues:

First up, the front brake keeps squealing whilst I'm riding, gently pulling the brake stops it from happening, but after a while it starts again. I've given the pads and rotor a wipe over which has sorted this in the past, but no joy this time.

And second, the Allen key socket on the retaining screw of my rear brake has rounded, meaning I can't get the pads out! :roll: What do I do!?

I've got Avid elixir 3's with SS kevlar pads.

    some noise is normal. it will go. and come back and go.

    take the pads out and clean the caliper as you should have done when you changed the pads.


    drill it out. grip the rest of the pin and rotate it. have fun it will take time.

    If you can, hacksaw or dremel a screwdriver slot across the bolt head....

    Jast hacksaw through the bolt and conical spacers.

    but he will still have the pads stuck.

    For the rounded bolt try a bigger torx type and tap it in with a hammer it might grip it enought for you to loosen it.

    Oh yes... Grab is with some mole grips as tight as you can and twist.

    Have tried with mole grips, no joy, will perserve though. I like the cut a slot idea, although it might be a bit hard to get at. Fortunately don't need new pads just yet, so there's no rush!
