I have a whistling noise coming from my car, this is only when moving. If I apply the brakes or am at a standstill, even if I rev the engine there is no noise. When I had service I was told my front brakes were 85% worn so could this be something to do with that?

SOURCE: engine revs remain high or increase when braking

Have you tried checking your throttle positioning sensor. Possible vacuum leak or check for carbon build up in the throttle body not letting the throttle valve shut all the way.

SOURCE: brake pedal pressure "whistling" whether totally stopped or braki

There is a seal where the rod from the booster connects to the foot pedal that is probably leaking

This is not a rich mans car so its normal. Your hearing the solinod that lets you take the car out of park after the brake is depressed so the car can't be put in gear unless the brake is on. If the noise bothers you the soliniod can be found and wrapped in insulation like a rich mans car them you can ride on feeling like a rich man too. ( the Beatles sang that a long time ago) and its still true today.

open the hood have someone u trust sit in the car and put it in drive holding the break with it in gear tap the throttle quick if the engine looks like it wants to jump out its a mount issue granted it will move about 3-4 inches if there ok anything more you have a problem try it in both (D) and (R)
