Tyres yes, brakes not so much. The brakes are needed only to come to a complete stop, most normal braking is handled by running the motor as a generator to dump the energy back into the battery.
I sometimes wish people who make this argument would go sit in a sealed room with a running electrical car and then a running petrol or diesel car and tell me which one was the better experience.
I think the argument here though is sit in the car with the vehicle's emissions from non-existent to end of life.
I do agree that point-source emissions of the electricity being generated is a big advantage. Nothing sucks more than being exposed to vehicle emissions in traffic/city/etc.
The pollution from the production of the battery, the steel and the aluminium can occur well away from major population centres. They are centralised and immobile so there is a much better chance that in the future they can utilise more efficient methods or at least capture some of their emissions.
What about PM2.5? Do EVs do not use breaks and tires?
