Rear Caliper Carrier Bolts - To Grease or Not to Grease?

[vr-man 0]

Hi All,

 

I'm currently replacing the rear discs, pads, bearings on my VR6. As expected the Caliper Carrier bolts have been a sod to remove - 3 out, 1 left to go.

 

I have read lots of posts on the subject of these bolts and I intended to put some copper grease on the threads of the new bolts during re-assembly to make any future dismantling easier.

 

However, I have also read a post which said the Caliper Carrier bolts supplied by VW are pre-loctited. This makes me think to grease them is a bad idea......wouldn't want my rear brakes falling off :oops:

 

Maybe its better to just cover the allen head with waxoyl after assembly, at least then the hex tool can locate properly in the bolt head in case I need to strip it down again.

 

Does anyone know what is correct

Cheers.

Its not Loctite!! - the blue stuff is an anti-seize compound

The bolts which screw into the end of the guide pins do have a band of blue stuff on the threads. They are supplied with the new brake pad set with it applied already.

 

The 2 bolts which fix each caliper carrier / bracket to the hub ( part no. N0199123 ) don't appear to have any substance applied to them. I've got a replacment set from VW for the ones I virtually destroyed getting them out. Possibly there is some clear locking fluid on the threads already??

If you can't see anything on the bolt, there probably isn't anything on it. The old bolts will have been stuck in due to 10yrs or so of gradual corrosion. I'd just stick them in as they are, then if you do ever want to get them out again just soak them in penetrating oil first (PlusGas is the daddy!).

Could always take them out & put them back in every year to stop them from seizing solid.
