How to remove a brake disc seized to hub?

[sbridgey]

Just taking my brothers 106 gti apart and trying to remove the brake disc from the hub and it just will not come apart!

Currently I've tried s**t loads of penetrating oil spray and this-

What else can I do?

 

[sbridgey]

Never mind we just tried a hammer again it came off! Very strange...

If it was me i'd probably use an american screw driver...

AKA hammer

Aye, just batter the f**k out of it always!

 

[Wrighty.]

Get a length of wood rest it against the back of the disc and smash the shite out it from the back.

Used this method on my old 330ci.

If in doubt, give it a clout Si

Glad you got sorted mate, they can be stubborn sometimes

I remember a mate was doing this on his drive. Got a phone call, saying he thought they were part of the hub. And I was wrong etc. I drove 20 minutes to his house and gave each one a single hard blow with a hammer and they both dropped off lol.

This one was being ridiculously stubborn, many many blows with a hammer and then a puller and eventually a bit more hammer abuse and it fell off!

Should have mobilized the sledge!

Worst one iv had was on a clio actually... Was stuck solid, hit it that much i smashed all of the disc off and i was left with the part seized to the hub.. Had to cut it off >.<

My 106 diesel was the same. I really thought I was going to break something and then the lightest tap knocked it off.

Really good whack with a hammer and it will resonate and release itself. Repeat until success.

I've had that on a scenic!

Remember to copper grease the new one when you put it back on the hub

I had similar with a ford cougar, it came off eventually but there wasn't much braking surface left!

Interestingly Brembo specifically advise not to do this IIRC... Don't know why.

 

[bozothenutter]

Galvanic reaction probably...

Never do this just make sure the mating face is clean and free of corrosion
