Seized Brake Disc
Hi Folks,
I need some ideas. I'm halfway through changing the discs/pads on my car. One of the discs is totally seized on the hub and no amount of
hammering will shift it. Can you advise on a suitable way to remove it, short of using the gringer?!
Thanks,
Donny.

put the disc and caliper in a vice ( disc in teh vice ) and then get a much bigger mallet.

Lots of deep penetrating lubricant and just keep hittine the hell out of them.
Just had the same problem with my car, they do come off eventually.
Failin that use an oxy acet torch (but u may risk damagin the hubs)

Oli

Get a bigger hammer.
Make sure you hit the disc all over, including agains the surface the wheel sits against. This helps break the rust bond.
There are proper unseiseng agents (try your local motor factor) avalible that should do a far better job than WD-40.
Alternatively, heat treatment can work quite well if you have oxy-acetaline etc. to hand, but be careful you don't cook the hud bearing.

Use a bigger hammer and hit the side of the bell. It will break eventually so you can take it off in pieces.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

What car do you have ? If it is a Mondeo siezed discs are common , if they don't come off with a few light taps then the only way to get them
off is to use a club hammer and smash the discs to pieces . Hit the disc towards the center of car on the braking surface until it breaks off then hit
the shoulder until that breaks then using a small chisel between disc mounting surface and flange remove remainder. Before fitting new discs make sure
you clean all signs of rust from the flange . Have tried all sorts of methods to remove Mondeo discs , this is the only method that works. Brutal but
effective. H.T.H.

If it is anything like the old Montego discs two radial slices with a grinder is the only way --- very messy ,loads black carbon fromthe SG cast iron
disc.

Thanks for your advice - it's a Mondeo and it looks like I'll be knocking the s**t out of it.
Cheers! Donny

I had great difficulty removing the discs from my Sierra.
Right up until an ex-mechanic mate of mine came over and bashed them off... in about 3 hits!
The key was where to hit them. I was trying to knock them 'off' the hub by hitting the back.
He just hit the face in between the wheel studs a couple of times- this broke the seal and they were straight off!
Hope that helps,
James
