hello,

whilst trying to maintain my Passat Shed.......

I have sheared two caliper retaining bracket bolts.......despite using plusgas, heat and trying to tighten the bolt first !
my plan is to drill the remnants of the bolts out carefully using an electric drill.

does anyone know if the bolt holes in the hub on a 2010 Passat are straight through holes, or whether they are tapped?

any advice appreciated as this looks like it is going to be a nightmare......see attached image.

thanks for any advice.

They are clearance hole so not tapped.

If you snapped the head off the bolt, the rest of the bolt should be a clearance in the hole. And if you have snapped the end of the bolt off together with the nut, what's left would also be a clearance. Can't you just punch the remains out of the hub now?

^^^^ Wot 'e said.

You will need to remove the disc, but at least you will then have un-fettered access & there may even be enough bolt shank left to try again.

Getting the disc off with the carrier still attached might prove difficult. Most VWs you have to get the carrier off first.

The disc looks well used and they aren't very expensive. If it it came down it I'd be "clearancing" the disc to remove the carrier

OK, I've dealt with this before.

Take an angle grinder, and cut a slot through the disc either side of the caliper bracket.

Rotate the disc so this section is elsewhere. Smack it with a big hammer to crack off the cut section.

Rotate it back so the gap aligns with the caliper. Remove relevant components.

You should able to finagle the disc out of the caliper bracket.
If not just undo the disc retaining bolt and knock the bracket out, disc and bracket now free.

Different car same approach, disk replacement time and mr angle grinder to help
