MG MGF Technical - Help! Front brake discs

I am trying to change the front discs on my '98 1.8i, having removed the calipers etc removed the screws by drilling them out and still the discs won't move. I have tried banging them with a lump hammer heating with a blow lamp and also used penetrating oil, but they just won't move. Any suggestions would be most welcome, is there such a thing as a disc 'puller' that I could use?

Martin,

Try a standard hub puller, should work ok - did it on an MG Metro once.
Just make sure the arms extend enough to accomodate the 9.4" diameter of the disc.

Beyond that it's probably down to brute force & ignorance. Although at worst you could remove the hub & take it down to a machine shop & ask them to remove it with the heavy duty gear they normally have lying around.

Good luck,
Steve

Martin,
Soak through hub center and wheel nut holes with duck oil and then use a good lump hammer , no other way , just brute force, rotate the disc while doing this and it will eventually move.

You need to hit fom inside out. You need to hit REAL hard. I used a 5lb lump hammer and my arm ached when I was finished.

SO HIT IT HARDER! It will come off eventually.

Remember and turn the wheel 180deg every time you hit it or its will stay put. :-)

If you are using the lump hammer method put a couple of wheel nuts back on a few threads so when the disc eventually comes free it won't fly of and do damage.

sounds like the voice of experience mike.

Is your gearbox back on the road after the Highlander?

John, broken cable, now fixed, testing a device that will reduce this problem ;-)
Cheers Mike.

For info only.

Had to resort to taking the car to a workshop in the end, they had to remove hub and all, then use a press to separate them. The mechanic says he has never seen discs so badly corroded.

Martin, thanks for updating the bbs.

Had to replace front and back on my P reg VVC a year or so ago. After hitting the first disk with a lump hammer for about an hour I thought that there must be a better way. I loosely fitted 2 wheelnuts, stood my blowlamp on a piece of wood to get it warming the disk from the outside face and kept turning it 20 degrees or so and hitting it from behind. After a few minutes it came off really easy and so did all the others, they didn't actually get that hot but it certainly did the trick. Gardening gloves or something similar are a must.
