341 : Miss Iris & Miss Vicky - drivers in distress with an old bus

---

Miss Iris and Miss Vicky are two bus drivers.

Unfortunately, the bus they drive everyday is out of order, and today they are forced to work with an old bus that hasn't been circulating for months!

Iris and Vicky are puzzled, they have never driven such old vehicles!

And the brake pedal makes strange tricks.... sometimes it brakes and sometimes it doesn't! And it also makes a strange noise.....

Before starting the daily ride, they put the brakes to the test.... they don't really want to risk endagering the safety of their passengers!

However, this brake pedal seems really strange and totally unreliable ...
