Car brake dust can be more harmful than diesel exhaust – new study (theconversation.com)

Exposure to air pollution is associated with around seven million premature deaths per year across the world. When we think of urban air pollution, diesel exhaust emissions are often portrayed as a key culprit – rightly so, given previous research findings. However, our latest research shows that dust from brake pads could be more harmful to our lungs.

Wasn't this known for decades?

Brake dust is metal particles, they fuck everything up.

Yip, here in the UK there have been several diseases named after brake dust pollution!

But who is acting on this confirmed medical research?

Not just metal, some brake pads have asbestos. I'm surprised more people don't know about this...

Edit: maybe someone should archive that link before Trump shuts down the EPA.

I wonder how electric motors perform there. With regenerative breaking, there might be less wear and tear?

Regenerative braking makes pads last much longer.

Haven't finished reading the article yet, but just wanted to ask. Are there any alternatives to semi-metallic break pads for cold weather currently on the market? I understand that ceramic brake pads are not ideal for cold weather and also have copper fibers embedded for added performance. Also, I assume that the brake disk (rotor) also plays a role?
