Seized Front Caliper bolt
Hi when going to replace my front brake pads on my V40 2002 for the first time i found one of the brake caliper bolts is seized and rounded.
Is there a special socket you can buy to unseize the caliper bolt or any clues on how to remove this bolt. Checked YouTube and nothing sadly |

It's experimental, but the only way I've ever found to work, and even then it's hit and miss, root through your sockets for Imperial, or even better, whitworth ones, preferably a 6 sided one, there should be one ever so slightly smaller than what the heads are supposed to be, (from memory they're supposed to be 12mm heads, 3/16 whitworth rings a bell) then smack it on with a large hammer, and pray it cracks undone, the shock of whacking the socket on also helps break any rusty bond, although obviously you only realistically get one chance at it, two at best, then it'll be properly wrung off.

You need some single hex sockets, these grip the bolts a lot more firmly than standard sockets. I had quite a few seized and rusty bolts on my S40, these worked really well.

Agree with the above but make sure you have a replacement bolt available or you will disable the car until you can get one.

It's not easy, but with the car supported high enough on axle stands and the steering on full lock it's just about doable, and when I say crack, you know like old steel wheel wheel nuts, an audible cracking sound as it suddenly gives while undoing it, and then after that initial release then it's loose, that's what I mean.

I'm having similar issues with my brakes, in my case the bleed nipples, on the front, O/S the original had a sheered bleeder, so had not been bleed out, before I got the car, and the second hand replacement, won't move either, ive tried everything, heat a large hammer, cooling, then, heating, in the end, I gave up and ordered two new ones, ive just done a pad and Disc renewal as the brakes were very poor. luckily the rears were ok the bolts came undone ok and the bleed nipples were not seized.
