HPE front discs

[Per]

All, last item do be fixed before MOT time on m '78 is to replace the front discs. Byt the WSM and the look of the new discs they should pull straight off once the caliper is moved away and the teo bolts sitting between the wheel bolt holes are removed. Seems like it is held on with rust, so a big pulle and some heat + rust remover ought to do the trick? Nothing else holding it on?

They tend to grip on the rust on the wheel flange,  try giving them a  "thump" with a heavy mallet,   rotating a number of times whilst doing it.

It is quite often situation. I can recommend two methods - using of a large bearing puller or a high grade bolt and nut that you place into the hole dedicated for mounting the yoke, alternately top and bottom then rotate the disc a bit. In such a way you will easily press out the disc from the hub. It worked in my case unlike the hammer hitting. You will also find some tutorials on youtube.

I used a big puller and a bit of heat around the area where it grips the flange of the hub. Came off without a hitch. I just wanted to be sure I did not try to pull off the nut on the spindle while having been sent the wrong type of disc ......

BTW I am wary of using too heavy a hammer, you could damage the CV joints that way.

I offered a practical solution,  we don't all have access to sophisticated garage equipment. Take it from me,  use common sense and it works. If you don't apply common sense,    whatever you use will cause problems ! ! !

BTW, the reason for the scored disc was that the PO had fitted one pad the wrong way, i.e. with the backing plate toward the disc 

Ammy, proper use of a suitable hammer is OK. My point was that the inexperienced might be tempted to use a bloody great big hammer at full whack. That is a sure way of damaging the CV joints. But when they fail less than a thousand miles later the poor sod does not connect the two events.

You are joking.....!
