@Brimfull, a handy tip:

On your spare/refurbed calipers (assuming you have new nipples), whip all the nipples out & very carefully wrap only the threads with 3 or 4 turns of PTFE tape, taking care not to go past the end of the threaded section. This is easy to do when the nipples are new & dry. The PTFE forms a barrier to galvanic corrosion and the threads never seize, been doing it for years, it also helps seal the threads during bleeding.  “If it ain’t broke, don’t fix it” -where’s the fun in that?

Thanks for the tip

Gremlin's tip is spot on, standard practice for various items at sea, where the salty atmosphere tends to add to the corrosion problems

At the risk or de-railing the thread, I have a question -
As I keep reading about these calliper pins seizing, how long on average does it take after maintenance before the pins seize up again ? As mine is a 2006 I do not have this problem.

There maybe a member or two that has regularly removed these pins and cleaned them up / re-lubricated them to stop this problem, that could be an answer to the problem, it could help some members, especially those new to these cars, anyone

My pads were changed around 2 years ago and one had seized so not too bad. If you use new pins at every change that helps.

I always use that white aluminium grease stuff in the holes, I just hope it helps? “If it ain’t broke, don’t fix it” -where’s the fun in that?

Will certainly bare it in mind, thanks

I liberally coat everything with Mintex Ceratec as it goes on like normal grease but dries a bit which limits how much crap sticks to it. I liberally coat the pins and the surfaces of the caliper where the pads sit on it as it helps protect the metals and reduce the risk of galvanic corrosion. The BMW uses the same caliper design and the areas where the pads sit get eaten away once salt gets onto them, and the pins are also notorious for seizing. Luckily I've never had an issue with stuck pins although they definitely took some effort to get out when I first changed the brakes on it as the front discs were still the originals at 5 years old. Copper slip can work too as it's an anti seize, but the carrier grease is usually pretty thin and lightweight so it gets washed off surfaces pretty quickly, hence my preference for the Ceratec. I've used it for years on the Impreza too and it's stood up to having the discs glowing on night runs they've been so hot.
