Help!!

[lomax]

In a sticky bit of bother so need any help you can give.
I have was going to take the back break off to change the pads when i stupidly knackered the allen head of the holding bolts!!
Any ides of what i can do?
Was gonna try to drill a hole in the side of the bolt head and use a screw to get purchase to get it off, is this too drastic?

ohhh i had that happen on a exhaust flange bolt, the only way i know is to drill a hole in the remains and use a easy out i think they are called to extract the remains. You may get away undoing it with some multi grips or something like that if theres enough room. Always pays to use a good set of allen keys to. Hope you get it sorted .

Get a torx drive socket and hammer it into the damaged hexagon, works 9 times out of 10 for me.

If you have only rounded off the hex then a set of these might help.

Another way is to "hammer" in a torx bit, it's a bit rough, and you need a good quality torx bit.

Where are you?

I have the Irwin removers if you want to borrow them.

I agree with Miz and i have a set "up north" if you need to borrow ,but also agree with the others .you could also try hitting it flat on the head(may shock loosen the bolt and also squishes in the head maybe enough to get the key to fit again) but as always caution if the bolt is in a fragile item(dont want to break a casing) another option is hammer and chisel on the corner of the head.

Still no joy
Have sent off for some bolt removal tool off ebay.
Screw in counter clockwise then bite so hope this will do the trick.
If not what do you think about giving it a whack with a coal chisel?

[shedmonkey]

i use that method a lot but make sure chisel is sharp and use it on the edge of the head so you are hitting it in the direction to loosen the bolt.

[Miz]

I would wait until you have tried your new tools before resorting to the cold chisel, in the meantime, it will pay to keep soaking the bolts in wd40 or similar.

Also, have you ordered any new bolts? And a tub of copper slip?

?

Will you need to drill the bolts? If you will, maybe consider my offer, mine do not need any drilling, they grip the outside of the head of the bolt, or even the shaft of a stud.

On a caliper bolt the other methods here should work, i bought these after my header bolt snapped, alas these didnt work so i ended up going to the pros to fix it ,cost me $80 but was glad to get my bike going again.
