When you are using the front brake, you have to be very careful. First you have to use the back brake, then the front brake. If you use the front wheel brake without using the back wheel brake, the cycle jumps. So first the left, then the right, always. Emergency time you use both brakes, but otherwise always the rear wheel only — left side.
On this particular day, I did not know that my back brake was not working. There was one very fat lady crossing the street in front of me. She was crossing so slowly. I immediately applied both the brakes, but my back wheel brake did not function, so my cycle went up in the air. Luckily I did not fall. I got the shock of my life.
Did you have any experience like that? I am sure there are people in my boat!
