    Rounded brake disc allen bolt

    Hi folks,
    Everything went ok today till this bloody disc

    I used the socket i used to use on my 535 but its slightly to big. Eventually found a proper sized allen key but its rounded on me now.

    Heres what im thinking to try next. If i whack the disc im thinking the head of the bolt will break at the disc, what do you think guys? Would that be too much for the wheel bearing?

    Are the bolts easy to source?

    Thanks, watty

    Got a picture of it watty?

    I would try to hammer something in there first as the disk could take a lot of wacking to break it.

    I had to drill the head out the one on my E36 when that happened.

    And you don't have to worry too much about replacing it. The wheel and bolts will hold it it in place It's only there to help you out when you have the brakes all apart to stop the disc falling off the hub.

    Ive tried hammering in a couple of things Ben but its a shallow hole like. Was hoping the head of the bolt would break if i whacked the disc

    Was thinking i might have to do that Ferret, hope not

    The discs and pads on it are still well meaty and i would just leave them for now but i want the disc off to give me better access to everything, bloody sods law

    As above, just drill the head off, won't take much effort with a decent metal bit. You should still be able to grip what's left with mole grips after the disc comes off if you want to remove it completely. Common problem on VWs because they tend to have a Philips screw in them which invariably turns to dust when you try to undo it

    Ahhh right, you are talking about the little grub screw that holds the disk on
    Like has been said drill it out or I sometimes use gas if I'm lazy.

    I find a impact screw driver will undo them most of the time no worries, if you try to use hand tools they always round off!

    Once the pressure is off and the disk off you can probably spin the stub of it our with moleys
