Caliper slide pins.
What if anything do you grease/lube them with?
I've got my trusty old copper-slip for the pads so that is ticked off. However nothing at hand for the slide pins other than some white lithium spray grease. (that always goes think and sticky) Might have a decades old tub of LM Grease buried at the back of the garage. Suggestions?

I change recently my brake setup and clean and grease all slinding pins by using this one: https://shop.ahw-shop.de/original-vw-au ... 470?c=6270

It's a kit for the rear brake bin but you can use the grease for the front pins also.

Cheers. I posted before I'd sat down and had a real look. I found these this morning on Ebay. I was only searching for appropriate grease but new slider pins are not as expensive as I thought.

Brand new pin from VW dealer or official shop are expensive.

Be aware of fake products on eBay.
To be honest, after cleaning my pins were looking brand new even after 120000 km.

For the grease, VW official or TRW PFG110.

Cheers. Yes lots of the cheaper pins look more than a little suspect quality wise. I need to pick up some disks and pads from Eurocarparts. I'll see if they have anything suitable on the self.

Front pins on the ATE calipers I used to grease but no longer do. The workshop manuals on ErWin also do not say to grease the pins either, just clean and refit.

I recently changed the pins, bushes, and springs on both of my front calipers after they started making clicking noises and found the top bush on the driver's side caliper was split and the grease was all in the backside of the bush not where the pin actually seals with the boot.

Just buy the ATE pins bushes and springs from the likes of autodoc at the fraction of the cost. The dealer quoted me £22 for just 2 bushes and pins and I got 4 bushes, pins, and 2 springs all ATE for £50~ delivered.

On the driver's side (which I installed incorrectly) I used grease and the bushes just absorbed it all in 5 minutes so I suspect using grease with them will eventually cause swelling. If you do change the bushes, push them in toward the ears of the calipers DON'T pull them in toward the piston like I did.

I used this video, just don't put the bushes in like he did.

Brake pedal feels a bit better and pad wear is much better, plus the clicking noise is gone

I'll try and get some pictures of the manual and the old bushes.

I just use silicone paste. Does affect any rubber parts.

Did this about a month ago for my front calipers. They seemed to be dragging a bit and probably not retracting enough. The exposed part of the pins were gunked up. Cleaned with light scotch pad and gave a light coating of silicone paste and all seems good after that.

That is exactly what I do/use as regards the guide pins either every year or every other year, my tin of Copper grease has very few uses these days seeing as it will swell up the rubber parts.

On the front callipers you should actually clean the hole where the rubber bush for the slide pin sits.Because aluminium oxide. - Meaning its better to clean the hole, and put some light film on grease on outside of the bushing when installing it.
The pin doesnt need any grease, but you can put a light film of grease to prevent any corrosion etc.
