Why does my caliper paint keep chipping off here?

And before you ask, it's because the caliper paint adds 5hp.

This is just the caliper plunger, so I'm wondering if it turns when it activates? I also hardly ever use my brakes, so maybe it just never bakes on properly. wondering if anyone else has this happening.

Isn’t it like billet steel or aluminum? Very hard to get paint to stick without proper preparation. Light sanding/scuffing to give the paint something to stick to and a proper primer.

But how much range loss?

That’s an odd place to lose paint, just 1 or all 4? If just the one I’d think a leak. If all of them I’d think just not cleaned well enough. I ended up polishing mine because I wasn’t going to paint them. I had to polish because ‘iron off’ made them look terrible when it came into contact with that area. It stained them black so there was some sort of reaction, perhaps a SOS pad them a bit and use rubbing alcohol before the next try.

there is adhesion products like BullDog (fyi smells like hell). The caliper body is cast aluminum, those plungers I think are stainless steel.

It’s made from aluminium. Did you use the right paint?

There are no moving parts on the outside..

My understanding is that even if you don't press on the brake pedal the Blended Braking System that One Pedal Driving employs will invoke the physical brake force along with the resistance of the electric motor to slow the vehicle.

Thanks for this info, and I ask if there's a way to confirm what you said. My thought behind one-pedal-driving, which is very cool, was "i'll save my brakes a bit".
But if what you're saying is true, then we OPD users will use brakes as normal.

Dozens of posts on this. All modes of driving use blended braking, and then the physical pads at the end of the stop (or in a sudden stop). You're not saving brakes in any mode, they're the same.

My wife and I had a 2013 Ford C-Max, it had regenerated braking. Bought pads for it to be ready to change at moments notice. Never used them and it had over 275K miles with original pads and rotors. If only my son’s gf didn’t drive through a red light and get t-boned. (She’s ok, car wasn’t). It wasn’t a brake issue, as there was a tree crew waving cars through the light and she read the room wrong.

Lack of prep and no primer.
Last mach-e I wet sanded, and rinsed off with brake cleaner.
use an etching primer, then paint, and clear-coat.
wet sand between coats as necessary

nothing moved after 2 1/2 years ish
