.... to remove a welded on brake disc? ???
I need to change the rear discs and pads on the Mondeo and made a start this afternoon, only to find that the disc is welded on. ::)
When I did the fronts last year I smacked 7 bells out of them with the sledgey. One came off whole, the other in pieces.... :D
Given it's New Years Day and some of the neighbours have family and friends round, I refrained being a considerate chap, so squirted lots of WD40 around and gave it some light taps with the hammer. ::)
Tomorrow however.... ;D
Unless someone comes up with a better solution. Heat perhaps? ??? :-\
-
Gentle manipulation with 'sledgy the hammer' should see you right.
-
Must admit my first thought was heat,but would that run the risk of damaging the bearing in some way?Best rust buster I've found is a 50/50 mix of atf-u and acetone.Local stealer uses your primary method of "Sammy".

A puller ?

Who are you calling a puller? ;D

No special tools available. :(
I have a range of hammers in different sizes, a blowtorch and a gurt big iron bar.... :-\ :)

Thanks BG! :y
I havn't taken the caliper bracket off yet, but I took off the caliper and took out the disc screw, gave the disc a tap with the hammer and it's rock solid. ::)

I had this problem on the MV6 last month.
I tried a little 'light persuasion' but I wasn't prepared to hit it hard enough to make it let go.
Plan B was to take out the retaining screw and wheel bolts - started the engine, stuck it in 'drive' and applied the brake repeatedly until the disc released it's grip on the hub. :y
The disc can't go anywhere because the caliper is holding it in place.
Edit - the drag in the gearbox is enough to turn the wheels so no need to apply lots of throttle - just press the brake each time the disc starts turning at about walking pace until it eventually lets go.

Old school, workshop practice,, before the elf's. :y

For whatever reason the mundane-o discs take quite a bit to knock off.

Yes it was a hell of a job when I did the fronts last year. ::)
Ended up smashing one up... :o

Oops - my reply isn't going to help in getting the rear discs off a wrong wheel drive car ::)
-
Is the hub bolted to the trailing arm?
If yes, unbolt it and place the disc face up on a couple of blocks and smash ten bells of shit out of the centre of it to knock the hub off the disc ::)

OK are they deep sleepers ??? good, won`t take you more then 30 minutes to get the job done if you start it now ;D
I never hammer from the rear of the disc, there`s always a risk of hitting & deforming the caliper bracket mounting points. hammer it diagonally across the front face.
The folks next door will just think you`re ringing in the new year......again :-X
-
When they do come off, refit with some copper slip for ease of removal next time. :y

Wire brush the hubs first - something you should do for any hub face mounted disc. This is a perfect job for a cordless angle-grinder with a cup wire brush.

Well it came off in the end with much hammering, bashing and bad language! ;D

It’s almost like the hub and disc hat are an interference fit I’ve had wheel bearings pop out easier 😂😂😂
I saw one of our guys hit one repeatedly so hard until the hat separated from the disc 😧😧😧😧😧😧😂😂😂

The fleet repair co. who serviced the vehicles for the company I last worked for used a really quick & easy method. But of course they had all the kit 8)
The technician first assembled a 3 legged puller on the disc & got some tension on the device & sprayed a lot brake cleaner fluid up behind the disc
He swopped the windy gun for an air hammer & hammered on the front face of the disc where it sits on the hub. I`d say after about 2 minutes of this deafening treatment & with his mate increasing the tension on the puller the disc popped off. ;D

That's pretty much how I got the rear discs off the Jaguar hubs when I broke it, too.. although replace "air hammer" with "lump hammer" and "popped off" with "came off with such a bang I thought a bomb had gone off" ;D

The boot came off much easier. As did the engine! ;D
