How do you know when you need a new fuel filter on a honda accord?

When I stop my car and have my foot on the brake, but when I release the brake my car makes this noise like it's going to give out everytime I stop while I'm driving... What does that mean?How do you know when you need a new fuel filter on a honda accord?Could be a vaccum leak. The brakes on most cars are boosted by engine vaccum - a tube from the intake goes to a booster to make braking easier when the engine is running. If it happens when you apply or release the brake it may be that you have a leak in your vaccum hose or brake booster fault.



BTW you should change your fuel filter every 20,000km.
