If they are vented then maybe you could get a long lever between the 2 faces and pry them off? Or possibly get a slide hammer hooked over an outside edge.

I normally resort to a large three legged puller - wind it up tight, then start hitting the back of the disc whilst nipping up the puller.

This was my contribution to this thread, drastic but 100% effective in my experience

viewtopic.php?f=3&t=41706
I had the "brake disc is never going to come off" experience about 18 years ago on a ford escort.
Even heating it up to a glowing red with an ocy acetyline torch and belting it with the lump hammer wouldn't shift it.

In desperation I came up with a method which worked a treat then, and I have used it several times since on various vehicles with success. Its certainly less effort than fruitlessly banging away with a hammer.

I got the hacksaw out cut four slots in the brake disc itself, and simply inserted a large cold chisel in the slot/slots as necessary and gave the chisel a sharp whack with the hammer. The disc itself just shatters and falls off the hub. The disc has always cracked right across the middle on all the occasions I have used the method to date.

kind regards

Neil

Watch the hot dust on the brake hoses if you opt for the grinder. I think I'd go for the hacksaw myself in that area. Sounds like a good method Neil. I've never had the problem of a stuck brake disc, just them torx retaining bolts with knackered heads.

Perhaps I just need to gera-biga-hamma!! And be less timid with it.... I thought it was hitting it pretty hard, but perhaps not!

Try my method Richard only one sharp blow with the hammer on a cold chisel, on one of the 4 slots in a vertical position, doesn't even have to be that hard!

Hit the outer EDGE of the disk not the back.

Remove the disc retaining screw, put car on stands, both driven heels off ground make sure it's secure. Run it in gear up to a decent speed and brake. It should grip the disc and it should break free of the hub..

I did try that, it wasn't for shifting easily!

I'll probably try again in a couple of weeks - the OS is not so bad, worst comes it can be removed with the hub, then separated afterwards. NS more of a problem if it is as stuck, as not planning to change the bearing!

I did the rear brake on the 307, seems there is a bit of float on the bracket and I had set it too close to the disc; filed some off it anyway, so have plenty of room now! Took off the turbo outlet pipe; O ring is present and not broken, put a few turns of PTFE tape round it, see if that stops it weeping.

Warm and sunny here today - hard to believe that I failed to get to work on Tuesday as there was heavy snow!

It's amazing how the British Weather is full of variety...

Cold and foggy-damp down here at the moment... You have the reverse - for a change :) Enjoy!

Same at ours - 17 degrees and sunny! We actually took the wee one down to Strathclyde park for an hour to play in the sand for the first time! :)

Had a think - pretty sure I've got some angle iron lying about. 30 mins with the MIG should see a frame made up that I can slip behind the disc, and then insert a scissor jack between it and the hub centre to act as a puller - got a jack from a ZX that will do 8-)

That has got to be worth a picture or three Richard :)

Fingers crossed it works [-o<

Series of 4 video's this is number 1, of 2 Americans over-complicating the N.Falcon patented method of "stuck rotor" removal.



The hacksaw is equally effective as the angle grinder, less noise, less sparks, not a great deal of effort cuts the disc well enough. The little cut with the dremmel across the front face could help the "path of weakness" but probably not necessary.

Instead of faffing about with bolts through the caliper holder, the cold chisel (reasonably meaty of course) struck downwards from top to bottom of the cut, simply spreads the cut open and with nowhere for the force to go it just cracks the brittle disc right across the middle to the cut opposite, and the disc falls off the hub.

You could reserve this as your last resort, but to be honest if 10 minutes of banging with a hammer doesnt shift the disk, I use this as my first resort. Worked every time so far.
