Hi All
New problem today.
With the engine running, there is a hissing type of sound coming from near
the top of the brake pedal. Step on the brake pedal and the sound goes
away.
I have the Bentley for my car, but I can't seem to find where there may be a
vacuum hose or what ever that is leaking.
I have dug around in there, but can't find where the leak is as of yet. It
is definitely right close to the brake pedal.
Any ideas?
Thanks
