everytime i apply my brakes even when stationary, i can hear a hissing sound, it becomes more noticable the more pressure i put on the pedal.

i have also noticed in the past few days the brakes have become worst and worst even at the point i was pushing down as hard as possible and the brakes felt at 50%.

i havent got much time to take the car to a brake specialist as i need the car 24/7, so any help would be greatly appreciated.

Sounds like your brake booster - my son inlaw had the same problem

brake boosters got a crack/leak, replace it asap..

mine went while i was driving, and it was not fun trying to stop the car in traffic.

thanks for the help guys, i got worried and didnt even bother to search even though there is 50 other threads on the same thing.

its all fixed now, thanks for the help.
