I think my vacuum pump may be getting a bit tired, or alternatively I
may have a small leak in the vacuum tubing somewhere.
I was thinking that the brakes were maybe a little softer than I'd like,
so when the truck was serviced today I asked the mechanic to have a good
look. He bled the system, which has helped a bit, but also pointed out
repeated pumping of the brakes when at idle uses vacuum faster than the
pump provides it, causing the brake warning light to come on.
You have to pump repeatedly and fairly fast, but I'd be interested to
know how other people's brake systems perform in this respect to try to
get a feel as to whether I have a problem or not.
Any volunteers to go pedal-pumping at idle to let me know what happens?
And if I do have a problem does anyone have any experience of fixing the
pump? Or other things to look at, such as a leaky pipe? I know how to
use soapy mixture to look for air escaping, but are there any tricks for
finding holes in a vacuum hose?
Thanks
