Caliper Service

Red rubber grease or coppaslip will do. Or even silicone grease.
As long as it isn't a high speed application , I would use any of them.

Can you get replacement caliper slide bolts to eliminate movement? Had similar movement on rear brake on the gixxer, didn't affect performance. Sold before I got any pins.

 

I use copper slip personally. It's only to stop them seizing

 

I have just recently fitted new pads back and front on my 2012 Bonnie.
I always use copper grease on any thread that does not require threadlock adhesive, and any sliding steel to steel components.
I put Copper grease on the rear of the pads to stop any brake squeal and also on any contact points between pads and caliper.
On the sliding pins that fit in the rubber bellows and the pistons I always use Castrol red rubber grease.
I like it that the caliper 'floats' a little bit,

 

As Gary said Copper slip every time for me also

 

Copperslip is not good at all. It is mineral based that will make the rubber boots swell.
Silicone grease or red rubber grease is good or even the grease that comes with a chain pack(Lithiam I think). The boots will swell about 30% which then opens there seal to the elements.
Also avoid high melting point/general purpose grease or moly grease

 

Never found coppaslip to do this ! Been using 20+ years on bike and cars. My old series land rover had around 2 tubs of the stuff all over it, great for stopping corrosion and keeping stuff moving in our wet salty climate.

Handbrake mechanism on my Freelander has been painted with the stuff, and this is the first year I haven't had to strip and rebuild for it's MOT.

 

Just use google. Its all over it, and I've seen many like the ones in the photo. So that's why I avoid it. Copperslip is great used in the right area.

 

Copper grease is generally used for anti seize on threaded fixings, and is highly recommended to stop thread seizure.
It is also used for high temperature applications such as brake calipers, (not rubber seal areas) and on the brake pad steel face that touches the piston to stop that horrible brake sqeaking noise.
I personally like Castrol red rubber grease for rubber seals etc. and recently blathered it on my forks before fitting the fork gaiters.

A good product and I have used it myself on electrical type fittings.
Not the best for mechanical applications though.
