312mm brakes question

[joop200789]

went to swap the brakes today on the car. found a problem i couldnt get the old disc off,it looked it was held on by the drive shaft hub nut? if so any one know what size it is as its bigger then a 32mm socket (largest one i had) and also its a bi-hex nut

it's not held on with anything other than 1 screw.


the centre is 35/36

what you need is to spray wd40 around wheel locating flange and give disc a good knock with hammer. It's located on a taper.

as above and maybe a gentle tap from behind with a rubber mallet to help it on its way

cheers guys, i dint have any wd 40 wi me but i sprayed it with brake cleaner and i did give it a tap from bhind must need a bigger tap lol dint want to hit it too hard and brake the disc in case it where held on with the hub nut or i would have been screwed for work

Just make sure you undo the locator/retaining screw before tapping it, if your going to use WD40 be care with it as its a degreaser an can cause lots of problems around bearings & hydrolics

one tip if your going to 'tap' the disc off leave a couple of wheel bolts in the holes otherwise you'll be wearing the disc as a new smile!
