    Hi Folks

    Thought this would be an easy afternoon task, replacing rear pads and discs, got everything apart ok but the discs would not come free. Have tried heat, and a large persuading stick, but no joy. Any thoughs or does any one near Plymouth have a big hub pulller that would pull the disc off? Car sat on axle stands looking forlorne.

    Thanks in advance

    I usually go with a metal lump hammer from the back of the disc.

    The shock frees it every time.

    If that don't work, pullers would be a mega mission.

    Might sound like a silly question but have you removed the little screw that secures the disc to the hub? I did a disc change on a mates merc and the screw head was covered in grime so we couldn't see it at all and thought there wasn't any. We went mental with a hammer and crowbar then found the screw after spraying about half a can of WD40 all over the disc lol. Unscrewed it and it just fell off. Won't make that mistake again!

    Hi Westy, yes the retaining screw HAS been removed, I made that mistake 20 years ago, never again. Good call though.

    Agreed, as you are replacing them a good thwack will release them, failing that spray WD40 (Or CD-90) at the back of the hub tonight and smack it in the morning!

    Well if at first you dont succeed, use a bigger hammer.. They eventually came off with a lot of whalloping with a lump hammer... many thanks to all for their help.
