    i have a 86 2WD dually with a 454 auto trans.

    i noticed a leak that looks to be coming from a gold anodized canister thats between the valve cover and the hydro-booster. its says "caution" on it..

    what is it? my piece of crap Chiltons manual says nothing..

    That's the accumulator, it stores hydraulic pressure so if your engine dies you can still apply the brakes a few times.
