I second John's technique. Once you have had the disks off and on a few times the grub screw is no longer a problem.

30 for each disk seems very cheap. I think the Evo ones from a main dealer are about 80.

I have had mine skimmed in the past which has worked ok. It obviously reduces their life expectancy but is cheaper than a new set of disks (worth considering if you manage to trash a new set of disks)


is 30 quid each a good price ? (supposedly OEM parts from

Also, is the disc retaining screw 4 or 5 mm? (will need to buy the tool size before I start this job).

What are the chances of the screw braking, ive heard sometimes they need to be drilled out if seized, is this likely to happen?

Soak liberally with your favorite penetrating oil.
Take a hammer and a punch that will fit inside the allen socket.
Hammer with discretion.
Make sure the allen wrench is fully seated before turning.
Use anti seize on the bolt and the inner part of rotor when reassembling.
This technique has never failed me.
