I drive a Ford Fiesta Classic, 2008 model, clocked over 97k kms.
Yesterday, When I left office at night, the surrounding was very silent and I observed a hissing sound coming from near the pedals below steering. I suddenly pressed the brake and stopped the car, but the sound disappeared. When I released the brake pedal, the sound again came. This sound is related to the brake pedal for sure.
The sound is still on even with hand brake engaged. Only a pressed brake pedal stops this sound. I don't find any decrease in braking performance, till now.
I showed my car to a local garage today morning, he said it is okay. But, as it is related to braking system, I am worried.
Anyone had a similar issue or know about this, please give me suggestions.
