Air has entered one of the brakes and needs to be bled. Once bled and oiled, it will be fine. I couldn't do it myself, but I have the oil and will provide it with the bike for the rear right-hand brake. The left-hand front brake is okay, but it would be better if it were oiled as well.
You can collect it from any of these locations: New Market, Katabon TSC, Dhaka University, Shahbag, Hatirpool, Bangla Motor, or Elephant Road.
Call me if you want to buy it.
