Fitting new Caliper bolts.

[Rmachines]

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.

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

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.

i will visit a few places tomorrow and see what i can come up with.  would 8.8 be ok ?  surly if i did them up tight its not going to go and fall out is it?

cheers.
