Removing front disc - rounded bolt head...
Discussion
Reduced head bolts aren't they?
Have you got a sacrificial 6-point socket you can grind down to remove the internal chamfer?
I changed my brake discs a couple of weekends ago, they are capheads on later cars like mine but they are bloody tight so I gave them a decent whack with an impact screwdriver before winding them out.

Spell that out for me, I don't mind sacrificing anything to get this bugger out. Need to find replacement bolts somewhere (nothing obvious on caterham parts), silly bloody idea to use such flat heads...Have you got a sacrificial 6-point socket you can grind down to remove the internal chamfer?

The bolt heads have been shaved down for clearance, most sockets have an internal chamfer so it doesn't purchase well on these bolts, if you grind the chamfer off more of the socket will bit the bolt head. From memory its a 9/16 head, I've a ground socket here in Berks if you're not too far away
Caterham will be the only source for replacement bolts unless you want to make your own

Russell, I just worked out what you meant with removing the champfer. (Also missed your explanation Mark as I was uploading the pics, appreciate the offer!)
Filed down the socket in a vice, hammered it down flush and off it popped, magic! Will save that socket off for all future disc changes.
Much appreciate the help all!

sharp chisel and hammer it anticlockwise ...a proper good slug with a hammer should turn it unless theyre silly tight
This is pretty much exactly what I was going to type. If it absolutely refuses to budge, than a nice new shiny nut welded on top of the hex will sort it (assuming you have a welder handy, or know someone who does).Cut slot with a dremel and use a large screwdriver to remove it or drill a hole slightly smaller than the shank and knock the head off. Lift the disc off and then use some mole grips to remove the shank from the thread. As soon as the head is removed and pressure released, you should easily be able to get the rest out - been there, done that...!
