Question:

What is causing a noise in a 1986 Ford F-700 brake system hose?

The truck has a loud buzzing sound on a hose that comes from the electric pump motor area. The hose comes from brake master cyclender to another gadget that has multiple hoses in and out of it. The hose is closest to the firewall and driver front fender. We replaced the electric motor. Motor seems to be working fine and so do the brakes. Just the loud noise. Any clue?

Answer:

if its a metal intake than its normal, if its plastic better try and reinstalling it.
i might have cut back the element off once I first say how low it became. It in straightforward terms must be low adequate to get chillier air as a substitute air trapped under the hood. i've got seen custom ones that pass contained in the wheel properly!? that could suck up water contained in the rain, no longer to show a deep puddle.
if that kit is installed wrong, like directed by or at a source of heat, then you get a hot air intake. counterproductive to what you are looking for. look at the thing carefully and see if you have it directed at the radiator or if it is not sitting too close to the exhaust.
Air in the system will cause a buzzing noise.
