I attach a photo of a rusty nut on my FF ceramics. 2012 28k About 50% have a tiny bit of surface rust. I'd like to deal with this now, before they start to corrode. They are 8mm nuts. Do I replace or treat them with some product? Many thanks guys. Belfry Image Unavailable, Please Login
For the time being I have applied a light coat of ACF-50 to each nut using a small paintbrush. This will stop the rust and protect for the next 6 months or so.
It might be better to remove the surface rust with a wire cup brush in a drill and then apply an anti-rust protectant.
11 years old. How much are new ones? Maybe just go buy some new ones and be good for the next 10 years. Having said that I have no idea how much they cost.
High strength metal compounds do rust, as stainless "additives" would otherwise make them softer. You may add a bit of rust protection, but I doubt it will sustain the heat of the discs for long. Even totally burnt it will provide some sort of protective layer, but judging by how clean these rotors are, I doubt you will like them with burnt residues. New nuts would be the way to go, but you must buy the one with the proper strength. Under normal circumstances, I apply some ATF oil (tons of corrosion inhibitor in ATF) in such rusty nuts. Not applicable to the rotors for obvious safety reasons.
If you’re looking for just the nuts, Pegasus Auto Racing Supply has them. I have them on my formula car brakes rotors. Sent from my iPhone using FerrariChat
Personally..I wouldn't really want to touch those. You must find out if those "bolts" can be retorted with new nuts. I'll bet they are a one time use torque to yield bolt and nuts set up, and the nut is probably a locker. Meaning if you attempt to remove it, it will destroy the thread on the bolt stud. They are designed not to come loose after tightening. I may I kindly suggest polishing a different set of nuts?
This is a 'new' car for me, so I'm being a little perfectionistic. I'm guess that it will be several years before these nuts become structurally impacted by this corrosion. The problem is that any future potential purchasers can also be perfectionistic, so I wanted to see what I could do at this early stage. I will probably try to resisting 'fixing' this.
If you are really serious about them, use a Dremel with a cloth wheel and polishing compound to shine them up and then coat them with high temperature clear coat like that used on brake calipers. You may end up only doing one, though, after all the effort and small cloth wheels it will take for the first one.
That looks like salt corrosion. Not a structural problem but not a good idea to remove them or wire wheel them in place. More harm than good and Tom is right about likely being lockers. There's only one full thread left so no room for error and its the bolt stretch that keeps things tight. You bought it so someone else will as well. Don't sweat it.
Thanks for everyone's replies. I ended up using a soft wire brush on a Dremmel to clean the surface, then I applied Cerakote Ceramic Coating which will withstand high temperatures. Image Unavailable, Please Login
Cerakote is the best. I'll also say that I've never met a Titanium 12-point nut that I didn't like. Ray
