Robert Jan Posted July 5, 2008 Share Posted July 5, 2008 Had a look at my Def 110 (2000) front brake calipers in preparation for their removal and noticed the bolts that hold them are not the normal type. They're basically a sort of "sun with rays" shape. What kind of bolt is this? Apart from the strange bolt changing the caliper seems not to be very complicated. (Although my experience is limited thus far to series drums.) /RJ Quote Link to comment Share on other sites More sharing options...
western Posted July 5, 2008 Share Posted July 5, 2008 either a Torx head or 12 spline hex head. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted July 5, 2008 Share Posted July 5, 2008 Mine are 12 hex heads 12 x 1.25 mm. They are dealer only. Yes I've tried normal 12 x 1.25 bolts and the heads do not clear the calliper. mike Quote Link to comment Share on other sites More sharing options...
western Posted July 5, 2008 Share Posted July 5, 2008 LR part number for caliper bolts from chassis LA930456 is FTC3375 M12 x 35mm. Quote Link to comment Share on other sites More sharing options...
Madcowz Posted July 5, 2008 Share Posted July 5, 2008 A 12 point socket from halfords fits nicely on these. Can't remember what size it is though as when I was replacing my half shaft and undoing all these bits, I wrote the sizes down in marker pen and it rained. chuffing great. EDIT: Ok, just popped outside with the socket rail and it is a 13mm socket. Quote Link to comment Share on other sites More sharing options...

tychoS Posted July 5, 2008 Share Posted July 5, 2008 Sorry A 13 mm 12 point socket fits the caliper bolts. A half meter breaker bar is advisable for loosening them - they have to be torqued to 130 Nm so can be a bit hard to loosen. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 6, 2008 Share Posted July 6, 2008 People get Torx and Spline mixed up. Torx has 6-points, and spline has 12. You can use an ordinary hex socket on a spline bolt, but there's an increased risk that it will slip and round the head off. The caliper bolts should have threadlock or torque seal on them. It's very common to find that someone has greased them in the past to make removal easier, which is a bad idea. Les. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted July 6, 2008 Share Posted July 6, 2008 Les. Wise words again I clean bot the bolt threads and the bracket threads with either a tap or a die. Which ever fits which. I check the bolt heads for any marks and renew if necessary. I then apply thread seal to the threads. As I've said in other places the thread seal does actually seal the threads from the outside elements unlike grease which can wash out.
