What size/type bit needed for caliper bolts?

[Leigh]

Nice quick easy question for someone..
What size allen key or hex bit will fit the caliper bolts on a cally?
I was gonna change my front brake pads today, but 2 things stopped me:
i) they don't need it yet..
ii) the biggest allen key I've got is too small for the hex/star shaped caliper bolts.

So I'll need to buy the correct sized bit/key...

thanks

10 mm for the ones holding the caliper to the carrier

7mm the one to split the caliper (only need that to change the pads)

as said 10mm for the caliper to leg, best bet is a cut off 10mm allen key a 10mm socket and a huge breaker bar (they are usually pretty well in there)

Get a set from halfords that go on a 1/2 drive ratchet (sp) one of the better investments I made in my tool set along with the in and out torx drive sets.

I'll second that. I bought both individually from halfrauds. They're expensive for what they are, but will save a lot of hassle like cutting up allen keys etc. Think they're £3-£5 each.

Cheers guys, at the moment it's just the two to split the caliper when I (eventually..) do the pads. £5 ain't too bad I guess. I bought a 1/2" drive 17mm socket to go with my breaker bar last year,and at the time you think "that's expensive for a single socket", but the first time you use it and find it's SO much easier (especially when I'd broken 2 normal extension bars trying to undo a wheel nut!), then it kinda makes it worthwhile..
Just wish I'd bought the breaker and nut a few years previous.
