Brake Caliper Part?
Had my calipers off to repaint them...but missing one spline-nut for one of the front calipers. This part sits inside the caliper to lock it in-place. Tried contacting Lexus, Brembo North America, even Race Technologies in Cali...with no luck on this part... Anybody know where I can get one of these for the front caliper without having to buy a new caliper?

I took mine off to have them repainted last year and (as far as I can remember) I did not encounter those nuts at all. The only pieces that needed to be removed were the two 14mm bolts in the back, the 2 pins, and the bridge bolt. Not sure where those "spline nuts" came from.

The brake calipers are aluminum and bolts are steel; heat in the brake system causes galvanic corrosion between the dissimilar metals, essentially welding the bolts to the calipers. These inserts are kind of like steel Heli-coil/TIME-SERT threaded inserts that folks use when they bork up aluminum threads and prevent the whole situation where you destroy the mounting ear threads when you take off the caliper.

They list it as a part that you can purchase on the Lexus of south Atlanta website.

I see now. The part you highlighted in your post is actually the bolt and not the pressed in insert. I wonder if they even sell these separately since they probably just consider them a part of the caliper sub-assembly. Sounds like your in a unfortunate situation. Maybe a machine shop can fabricate you one. I could probably make one here but turn around time might be an issue. If I can get the dimensions I can do some quick CAD and have it machined in my buddies shop.

Ok, well PM me if you need help and I will see if I can get in touch with my friend, I know he was out of the county on business but he should be back soon.

What you need is called a M12x1.25 flush mount captive nut insert. The biggest problem with it is the thread pitch. Only the Japanese do 12x1.25, so finding something in the US is going to be hard. If I were in a real pinch, I would chuck a lug nut in a lathe and cut it down to a light press fit on the hole since this is also the same thread diameter and pitch of most Toyota wheel lugs.
The bad news is, those look like they've been nitrided to protect from corrosion and fully harden them. Putting in a trimmed down lug nut would not be as good by any means, but it would get your car moving again.

Thanks everybody for the input on this one. I was able to get one fabricated. I wish Brembo would've been as much help as this forum has been. If this happens to anyone in the future...atleast they'll have something to look back on. Thanks Again Everybody!!
