    When I apply pressure to pedal, air is pouring out of this hole in canister so quickly the buzzer comes on within 10 seconds. Can you tell me what’s going on?
    Please and thanks

    Just make sure you know what you are doing before you go taking those apart. Big spring, lots of pressure, make face fall off

    Very good point. Takes me back........

    I cant remember the last time I saw a chamber with an actual clamp on the emergency side. Remember the little tags on the clamp bolts that said DANGER/Do not remove.

    We had a rookie at another shop not too long ago that got a concussion and knock his teeth out changing one.

    Understand what your doing, and cage it before servicing is always a good practice. I'll be the first to admit, I ussually just leave the brakes released and put vise grips on the pushrod.

    Nowadays, up here they have broken springs or the housings are rusted too bad to even reuse them anyhow.
