inconsistent hissing noise, like air escaping, apparently from around the pedals. Heard only at low speeds, seems to start first pressof brake pedal but if nosie exists, stops with the slighest pressure on brake pedal?

Hi there,

it sounds like your brake booster is failing, the noise is vacuum leaking out the rear seal as you apply the brakes, the booster will have to be o/hauled or replaced.
