Do black brake rotors stay black?
They will stay black (or relatively black) for about the first 100 miles… Yeah they come off pretty quickly. It doesn’t look so great once the paint or coating comes off.
Why are some brake discs black?
As far as I’m aware, the black on some disks is just an anti-tarnish coating, and will dissapear as soon as you begin using your brakes. The parts of the disk that don’t experience friction may stay black for longer, not sure for how long though.
What color should brake rotors be?
In normal circumstances, the car brake rotors (discs) should be of silver color or gray. However, under some conditions, they can turn blue. This is a sign that there’s something wrong with your brakes, and it’s highly advised that you take action as soon as possible.
Do black rotors turn silver?
When you receive your rotors, they will be completely Black or Silver. As soon as you install them and start braking, the friction from the pads will strip the zinc from the pad surface, turning it Silver and leaving the holes, slots, and the rest of the rotor zinc coated in the color you selected.
Why are coated rotors better?
Coating Benefits Summary: Anti-rust and anti-corrosive properties to ensure your disc rotors last longer. Reduced fitting time due to no need to clean. No chance of pad contamination due to rust preventative oils. Visually pleasing on the car – No ugly rusted hats or vanes visible on the vehicle.
Are slotted rotors better?
Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.
Can you get black brake discs?
you can get discs that are coloured (black) on the non friction bearing surfaces but i don’t know how well that coating withstands corrosion – i’d guess not very well as discs are very exposed and, due to the metals used in their construction, they rust readily.
How do you break in new rotors?
How to break in new brake rotors and pads

- Go 50 mph and jam the brakes just to the point of engaging ABS all the way down to 10 mph.
