My brakes have started to whistle at me. And I am no prettier than I was a
year ago...probably less so.
>From under the hood, the whistle seems to be coming from the brake booster ('76
MGB) or near it. When I turn the key, it is loud and nearly continuous. After
warming up, it whistles only when I exert pressure on the brake pedal, whether
or not I am moving. It is not a squicky squeel.
Two questions: if this indicates a vacuum leak in the brake booster, will that
affect my braking other than to make it harder?
How do I repair this problem? If it is the brake booster, where do I find info
to repair it? Otherwise, any clues as to how to diagnose?
