Gidday, My front disks are starting to rust, not on the braking area but the spokes. What's a proper way to prevent this without risk of getting slippery stuff on the braking surface? Paint or something? Any suggestions would be award winning. NOTE: NOT RUSTING ON THE MAIN BRAKE PAD AREA Cheers
Now if I was a BMW owner, I'm sure I would have some nail polish in my toolbox. But I'm not......so I don't.
Remove the disk and use rust jelly to remove the heavy rust. Rinse, dry and lightly buff with steel wool. Mask off brake contact area and spray remaining exposed metal with clear lacquer or paint.
Would that be OK with the high heat of brakes? Given the strada doesn't get flogged, but I use Motul 600 in the dirt bikes for a reason. And automotive header clear coat (VHT) on my "factory" finish pipes works pretty well, so it might be worth recommending that if you're going to go through the effort to prep the disc anyway. It's only a couple bucks more.
Acrylic resin should handle upwards of 205°C (400°F). It is unlikely that the "spokes" on your disk brakes are getting hotter than that, but you could upgrade to VHT if you wish. Other coatings may also be applied such as TiN or ceramic which would prevent oxidation.
Hmm, not sure about taking the disk off just at the moment, but will certainly read up about this lacquer business, cheers
Just went for a mini ride doing errands before, noticed the front brakes were less effective ( must have oversprayed some WD-40 on them ). Riding around with the front brakes on for a while seemed to wear it off almost back to normal
