As with every golf i work on... the rear caliper bolts were siezed on mine. As they are all a mush of metal now i need to replace them.
If i was to find some standard bolts which fit, is there any reason why i shouldnt use them? With a dab of lock tight it should be perfecty safe yes?
cheers.

Im thinking of doing exactly the same thing mate, im sick of the thingys rounding all the time

I would not recommend using anything other than the proper bolts.
The problem with caliper bolts is down to galvanic corrosion. The bolts will be a different "metal" to the caliper. Therefore, use some anti-seize paste on the non-threaded shaft of the bolt, and under the head (where it fits into the caliper), and then fully coat the threads (put enough on them to seal the entire length which screws into the hub or caliper carrier) with some low strength thread lock. Don't use high strength thread lock - it isn't necessary, and you'll just end up rounding the heads the nex time.
Also, get a decent 6-point socket.

They need to be 10.9 grade steel for strength. Most normal bolts are 8.8.
Go to a good fastener supplier and they should have the right size, pitch and strength.
Size should be M10 x 1.25 x 21mm.

i was thinking of a yaughting chandlery tbh... some marine grade bolts should hold up fine

Galvanic corrsion, now thats somthing you dont hear every day!
You are correct though, copper slip and a good quality socket driver all thats needed.
I got Unbrako bolts in mine which i robbed from work
And i use Kluber anti seize paste on everything under the car or which is a Mofo to get off ie manifolds zausts saves on knuckle skin :laugh:

Got a link to that Kluber stuff?
I use Bostick Never-Seze - but it is firkin expensive, and hard to get hold of. Much better than any copper based stuff though.

What is the base metal of their anti seize paste?
And do they use any UK based stockists?

Its not so much about falling out as breaking. 8.8 hasn't got the strength for the force required to hold brake calipers on.
VW can supply you new ones, and you won't still own the car by the time they have rusted out.

Orbic will post anywhere in uk i use em for everything even wheel bearings and belts for the car.
dont buy kluber from em though that i buy through their uk agent.
I know they use colloidal graphite in there high temp stuff along with sodium and sulphides i think, defo not good to smell makes you cough when you paint it on somthing red hot!! nothing will stick to it even molten magnesium!. :evil:
They also do solvent sprays dry lubes (Molibdenum disulphides)
Synthetic of all the above, oh and wicked anti rust.

Company is called maintenance direct europe www.lubricantsuppliers.com (ftp://www.lubricantsuppliers.com). They have the white antiseize, Lubes with mso2 etc.
