You know...I've just never really been happy with the results

Over the years I've tried all types of paint and techniques. Primer, no primer, duplicolor caliper paint, regular spray paint, high temp, POR15 etc, etc, and I've just never had anything last longer than a year before it started to show rust again.

I've tried with new brake calipers, cleaned them THOROUGHLY, primed and painted with days to cure and with old stuff and I seem to get the same results.

I don't know if it's driving in the salt, the heat cycling of the calipers or if I suck at painting brakes, but at this point I consider it a waste of time and money for any daily driver I own.

Maybe if I had M calipers or something cool to look at but factory calipers on a 3.0 are not real head turners

I appreciate the kind words but if you don't believe me you can ask the wife...patience is not a word that applies to me

The whole cleanup didn't take more than 10 minutes and it involved some brute force, hammering and the right tool that did most of the work.

Maybe if there's any interest I'll do a quick video of the process for the other side and you'll see how QUICK and easy it is.

I would say that I've always had pretty good luck with mine, but to your point, I probably only put about 6000 miles a year or so on mine... Though I do drive it year round, rain, sleet, snow, salt and sun, I usually do 3 coats of primer followed by 3 coats of paint and a high temp sealer and always, always wash the calipers and wheels specifically when I give her a bath. I usually re-coat mine every 3 years, which sounds about right, I've owned her for 9 years and they've been a few different colors now My wife just told me she liked the new blue the best, must mean something as she's never said a word about them in the past...


That said, as you say, keep them clean and serviced regularly and it really doesn't matter


Nice work on swampy by the way - I am still highly jealous... if I ever retire my E53 for my E70, I will DEFINITELY do the FMU kit on the E53!

I use 3 coats of Rust Bullet primer:


https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1


I do 1 coat, wait 20 minutes and apply coat 2, then I wait about 40/45 minutes and do coat 3.


Let that sit for 24 hours and then use POR-15 caliper paint to paint them out.


For the POR-15 I do the initial coat, wait about 30 minutes and apply coat 2, then I let them dry completely (about 4 hours) and do coat 3.


Let them sit for 24 hours and then I use VHT spray on sealer as my final coat - I'm usually lazy by this point and only do 1 "heavy" coat of the clear coat.


Let it dry overnight and bolt everything back on the next morning.

New parts have arrived!

We got an INA idler pulley and tensioner pulley, the URO aluminum water pump pulley and a new drive belt that I had in inventory.





"Lifetime" warranty on the URO water pump pulley was nice



But the quality of the finishing was NOT nice at all







I thought about returning the pulley but wasn't sure if I was going to trade up or down so I guess it's getting installed

Interesting side note. The INA bearings were made in Slovakia which was also the case with my Continental branded pulleys I replaced in my e46 waqon. The INA pulleys are $16 on rockauto Continental is $45. Only difference I could see was the name on the packaging



The new parts are Sox approved







I installed the water pump pulley with a little bit of blue loctite since I found a couple of the bolts were loose and you're not supposed to crank them on there.

Matter of fact...I think I use blue loctite on pretty much everything





That continental drive belt has a more aggressive looking thread pattern than most off road tires

I only buy parts from fcp euro which includes lifetime warranty on all parts. I am not a fan of uro parts from all of the quality issues I have read about....

Yeah I have read many quality issues with URO parts, however an aluminum pulley is a pretty safe bet I would say.

fcp euro is great...if you live in the US

The minute you have to ship things across the border there's places locally that I can find things cheaper. No they won't have a lifetime warranty but I'm used to getting shafted living in Canada.

And just in case someone is thinking it...the "free" healthcare is something that looks good on paper but in practice is not really working as it should and hasn't for a long time. I want my free shipping!!

I think I know how you did it. It's how I did mine. Wire wheel in a die grinder.

I'm with you on the painting. Used the Duplicolor caliper paint and it sucks. Doesn't hold up worth a damn. Chips and scratches very easily. Going to give G2 a shot next time since it's a two part. Hopefully it will hold up better.

I first used a combination of a small hammer and large screwdriver. Bang bang chisel chisel will knock most of the loose stuff off.

The secret weapon, which I believe Purplecty mentioned earlier in the thread, is the 3M Rust and Paint removal disc. It is made of this black webbing type material that makes a wire brush look like a wet paper towel

This is it here



I found the purple one lasts considerably longer than the black material.

Those discs are a little bit flexible so you can push them into contours and such.

Also, you don't need to worry about metal wires flying off which is the reason I'm a strong supporter of wearing eye protection.

Whatever I couldn't get with the 3m disc I finished off with wire brushes but that was a small portion.

I like to keep a few of the half way worn down discs since the diameter is smaller I can wedge it in even more spots
