My son is replacing the front brake discs on his GQ. He has undone the 6 socket head cap screws but the hub won't come off. Is there something else to remove as well.
Cheers,
Bros.

Hi Bros, put the 6 socket head cap screws back. These hold the locking hubs, which don't need to come off, nor does the disc rotor.
There are two large headed bolts behind the disc caliper which hold the caliper to the axle housing. Remove these, then carefully pull the caliper away from the disc rotor. The pads will then be easily removed from the caliper. Use some wire or similar to hold up the caliper so it won't dangle from the hydraulic hose.
When fitting new pads, you will need to carefully push the caliper piston back into the caliper to accommodate the thickness of the new pads. Be careful the brake fluid reservior doesn't overflow while doing this.

From the sound of the original post i think he wants to replace the disc rotors not the disc pads & this is why he is removing the hubs

On a later GU with manual hubs you put the dial in the free position,undo the 6 allen head bolts & the free wheeling hub should come off

Thanks for the replies guys.
joc 45 :- Sorry, i should have stated that he wants to replace the disc rotor. My mistake.
donk :- He has got the f/w hub loose but it won't come away from the inside for some reason.
nowimnumberone :- Same as for donk.
Cheers,
Bros.

If it has never been removed before it will be pretty well stuck. Just tap around the edges in a circular pattern and it will come loose

Nice pickup!

The 6 x 10mm set screws first, then the circlip.

when you get the hub off , there is about 6 bolts behind that hold the rotor to the hub ,
clean the mating surface carefully ,you will need to check the runout on the face of the rotor , as i found the runout will be out of spec ,so a skim of the new rotor to prvent brake shudder will most likely needed , ( remember you are matching up a dirty old surface with a freshly machined surfaced ,)
