【ヤマハeバイク】ブレーキ鳴きがどうにも止まらないので、エア抜きしてみたよ【ディスクブレーキ】

After riding on sidewalks for about 500km since purchasing the bike, an unpleasant squeaking noise started coming from the rear brake. I tried all sorts of solutions, including adjusting the caliper, cleaning the disc, and chamfering the pads, but it didn't fix the problem. I suspected the cause might be air trapped in the brake fluid, so I attempted bleeding the brakes for the first time.
