removing the caliper mounting , to replace brake discs; B6 saloon

[markh75]

Its been a while since i was here, so i'll say hello first! Hello!

I need to replace the rear discs and pads on my car, and i got as far as removing the caliper, but cant undo the caliper bracket; its on with a spline socket; does anyone know which one i need to buy please? what size etc. My last car had 19mm hex heads, but the B6 has these spline headed bolts, i dont think its a torx, but then, i havent been under the car to get a good look at it.
Re; winding back and then winding forward the caliper; i know how to wind them back with the car battery method, but to reset the same way; is it best to refit the caliper in place before i wind them back up? (to prevent the piston from being pushed completely out of the caliper - or is the operation not as crude as that?). hope that makes sense!

hi mate, did you work out the size of the allen key used for the caliper mounting bolts?

Hi there, the Allen bolts i was not able to get the right size as the area around it is fairly inaccessible, lots of stuff in the way, it might be a torX, because i couldn't get my largest Allen key to work in it, it just spun. I would suggest a chat with a mechanic at a local VW dealer of garage, dont be fobbed off, by them, try other places; I've gotten some good info this way!

Sorry i cant help much more than that. I eventually took my car to the garage across the road from where i live, and he changed the disks and pads for me.

regards, mark.
