is the big nut in the midle holding the rotors in place ? if so, what size it is ?
i need to change my rotors.

 

I take it that you have a Disco I,, so yes there is a big nut and
you can get the tool from www.atlanticbritish.com

 

no actually it's a DII. but when I removed the wheel ( 6 months ago..) I noticed that big nut that seems to hold the rotors.. but I didn't looked any further..

 

On DII the front brakerotors are held just by the 5 mm (or 6 mm ?) setscew, and arejust sandwitched-in between the hub and the wheel be the wheel lugs.

 

They are also held on by a large #4 phillips screw that usually needs to be busted loos by a hand held impact driver after applying some penetrating oil.

 

ok, I found and removed the + screw ( what a pain in the neck to remove it !!! ) actually I'll need to buy a new one, the head is pretty messed up.

I'm not sure where are those set screw you are talking about. I didn't see anything else holding the rotors.
but maybe that's why I couldn't get the rotor loose..[&:]....... if there is a trick to it, please share !!

I need to change the rubber seal on the pistons, i'm missing half of one, and the rubber is really dry, from where I could get those ?.
it look like my brake (at least front left) got a little stuck and over heat, as I have a large ( about 1 inch wide) blue strip on the rotor, which indicate exessive heat....

I do all my service on my bike, but I never did anything on the Disco. and I can't afford to bring to dealer for anything right now..

 

Atlantic British has the caliper seal kits.

 

i'll check them out, thanks !! do you have any trick to get that rotor out ? it is stuck. I even try placing a piece of wood on the rotor and hit it with an harmer, it doesn't move !!

 

If the caliper has been removed and the phillips screw removed then use a bigger hammer, that is Rover number one tool besides duct tape.

 

That's what I meant by the Set-Screw [sm=smiley20.gif]
