Rounded off rear calliper bolt
Went to change my rear pads today and somehow the rear calliper bolt is now rounded off, what size bolt is it? I was using a Torx bit, is the correct? I did the other calliper fine last weekend but this caliper I can't get the bottom pin off and now I've found out I've rounded the top caliper bolt. Also the caliper moves slightly when I push it as I think I undid the bolt a bit before I couldn't move it anymore. Is this going to be dangerous?

The top bolt has a 6mm allen key size not a torx!
If you removed the pads then the caliper would move.

I'm having trouble getting the bottom pin out though, been wacking it with a centre punch but it won't move, but if I got the pads out I still wouldn't be able to get the rounded Allen key bolt out would I?

Re: Rounded off rear calliper bolt
To change pads on Rear don't need to remove the top and bottom slider bolts.
If the fitting kit pins are seized in they can be drilled out and new ones fitted.
Your rounded off top slider bolt will be a problem if you need to change disc.

Rear discs can be replaced without much effort even without removing the caliper - I've had them off a bunch of times. Basically the disc is tilted into the caliper and rotated out.
Seized caliper bolts is an issue for when (!) the caliper seizes on the sliding pins, so if the bolt is rounded off make sure you're aggressive on lubricating the sliders with silicone grease.
