Will highly appreciate support in understanding this strange phenomena.
I have a Vitz 2001 model. The CNG is added by the previous owner. The issue is whenever I turn the air conditioning on, I have difficulty in applying breaks. The break paddle get too tight (slang main, danda ho jati hai). It's more cumbersome on CNG and less on Petrol on lower speed. On higher speed the break works fine and the paddle is soft.
What is the reason, my mechanic says that it is usual with Vitz and every Vitz has it, I am not buying this argument, please help....
