Removing seized bolt!

matt_lumley · Aug 20, 2014

Hi all;

Not related to my corsa but none the less the principle will be the same. Me and the girlfriends dad were working on his e reg landrover 110.

Aiming to refresh the brakes we bought new calipers, discs, pads and brake fluid. When trying to remove the bolts which attach the caliper to the hub we found that they had been left so long they were rusted like hell!

Tried to get the correct size socket on it (star shape but the size I cant remember possibly half inch) but it is just so rusted that it has rounded off.

The bolt is sunk in to the caliper and also it is in a really stubborn place to get to meaning it is hard to get anything behind it (I.e. to hammer a smaller socket on it).

Wondering whether anyone has any suggestions before we just butcher the hell out of the caliper and hack it off!

Thanks guys and girls!

Screw extractor kit/bit. eBay , amazon your local hardware store should all stock them. Always handy to keep.

Heat it or try pipe freezing spray to crack it free?,

I think that may be the next step. Just got to be careful with heating it up so close to brake lines I think?

Aren't they massive those calliper bolts?

Doubt you'd shift them with that extractor set! lol

Quite big yes, I believe it was either a half inch or a 13mm bolt as I remember trying to work out which was a better fit.

Ollie930 · Aug 21, 2014

Oh I thought they were bigger than that, either way they'll take some shifting.

For sure! I think we have almost reached the point of butchering the calliper to take it off from the front. Doesnt matter about damaging the disc or caliper etc as I am replacing it all.
