Spanner sizes please

Hi All,

Bit stuck at the mo just had a small op and cant move much to measure or even look at some bits but need to start ordering stuff, for a Defender 110 td5 does any one know what tools (sockets, spanners etc) you need to replace rear brake disks & calipers - looks like a torx to get the calipers off but what size? and what holds the disks on?

Then theres the steering drop arm, damper and ball joint came off dead easily but now I cant find the socket big enough for the nut to hold the arm to the box (its the 4 bolt type btw)

thanks

13mm torx. dunno the rest... helpful eh?

13mm bihex or 1/2 inch bihex disc, caliper bolts 14mm bihex disc bolt 34mm drop arm ball joint nut

thanks guys all sorted, just need to get the drop arm off, angle grinder and swearing for this week end then!
