hi when using the brake pedal brakes are fine but when i take foot off whilest driving it seems to be making air noise ongoing is this a bad prob or an easy fix??

Check the vacuum pipe connection on the servo first, as the rubber connector can split but I suspect the diaphragm inside the servo is leaking and this requires replacement as it cannot be taken apart, you would need to remove the brake master cylinder first then working inside the car remove the link to the brake pedal, release the throttle position control, and if you have manual gearbox the clutch pressure pipe, then the four nuts holding the servo.

Not a particularly easy job owing to the limited space
