Hi there i have just bought a new rear disc and pads for my bike.
But im having real trouble undoing the nuts that hold the disc on.
They just don't want to move?? Any ideas on how i can get them out?

Thanks Matt

Maybe you need a penetrant of some sort to loosen the nut? Bolt-Off, PB, WD-40??

 

[mattwright]

yeah socked them in WD40 but still not moving

A little heat from a heat gun or even a carefully applied gas torch will probably do the trick...

Spot on Dean, they are locktited in and quite difficult to remove without heating.

They advise fitting new bolts, presumably because they come with the locking agent already applied in dry form. Mind you, not a word about a possible difficulty in removing them in the service manual, official or Haynes...I suppose dealers would use an air impact wrench fitted with a high-quality Torx bit though, not much resists the power of one of those.

If you re-use the old bolts clean the threads with a wire brush, apply some non-permanent locking fluid like Blue Loctite and tighten to 22Nm (16 ft-lbs).

Thanks for your help guys im gonna try heating them a little maby.
Ill let you know how i get on

Also worth trying.....use a punch that will just fit inside the recess in the top of the bolt, using a decent sized hammer strike the punch once quite sharply. This will fracture the locking compound and make removal easier; don't whale away on the punch, just one sharp blow.

I used an impact driver to start mine loosening. The manual type that you hit with a hammer.

WD40 is great, if you are trying to Displace Water. For loosening bolts, use PB Blaster. If that doesn't do it, a little bit of heat. Don't want to change the temper of the disc.

PB Blaster is my new friend. And an impact hammer. This past spring I had a heck of a time getting the brake disc set screws off my wife's MINI. The PB Blaster and impact hammer was the trick. A trick discovered only after I had to drill and cut out two of the screws.
