while the wheels are out getting powder coated I noticed that the bolts holding the disc rotors to the black aluminum carriers were not that tightly bolted on. they all removed fairly easily. so now that they are apart I may as well refinish them as they are coated with brake dust. do I need to finish them with a brake fluid resistant coating or can I get them powder coated? also should the disc be red locktited in afterwards? without looking around anyone know the torque value for those bolts? id also like to reground the discs as they are still thick but slightly corroded from sitting. do they need to be mounted for that or can they just be brought to a shop once they are remounted to the carriers?
thx

Unless you can trust your powdercoater to mask off areas where the disks mount to the carrier and where the carrier mounts to the wheel, then I'd pass on powder. Might be better to just have them blasted and paint them yourself. I'd replace all of the bolts with new of the same grade and use medium strength thread locker (I don't go by color, because different brands have different colors for each strength). The disks should be mounted to the carriers for resurfacing.
I just had the rear disk for my Convert resurfaced by Truedisk and the fronts were done a while back by Nolan Woodbury.

as far as paint, does it need to be a "special" paint? I only have access to krylon type paint. do I need to have them automotive painted regarding brake fluid?
thx Charlie

Hey Charlie, actually going to send them off to Tom at Truedisk. told him you pointed me in his direction :)

Cerakote should be the ticket for that....lots of places who do it in the US too.....

I've found that Duplicolor High Temp Engine paint ( https://www.duplicolor.com/product/engine-enamel-with-ceramic/ ) holds up very well, as does POR-15 Top Coat ( https://www.por15.com/POR-15-Top-Coat-DTM-Paint ). Duplicolor Caliper Paint would be an obvious choice, but I've never used it: https://www.duplicolor.com/product/caliper-paint/

I used red wrinkle paint on mine nearly 30 years ago. Only a few small chips since then. Very durable and they recommend not using primer. I got mine at the local Harley dealer. No doubt the formula has changed since then.
This would be a good time to get the disks Blanchard ground. Mine were not warped in the usual sense but actually varied in thickness and gave the familiar pulsation. That went away and they have been good since.

These are easy to screw up. I would not disassemble the discs from the carriers without marking both so they can be reassembled in the same orientation. I suspect they were final machined at the factory after assembly, with no expectation that they’d ever come apart.
I would not refinish the carriers without a plan to true up the discs after reassembly to the carriers - masking the exact pattern of the mating surface of the disc onto the carrier is nearly impossible.
Light corrosion on the discs is not a major issue - it will rub off quickly when the brake is returned to service.

too late, already separated. they are going off to tom at truedisk for a refinishing and trueing. seems like good prices and quality services
