I don't think I've ever heard anything so irresponsible.
The sender on the brake servo is giving a very simple message - instead
of the nominal 140 bar assist pressure, there is (nominally) less than
107 bar. There are a number of possible causes for this, but the
general consequence is - there is insufficient brake assist available to
provide safe braking.
Forget the bullshit about 'twenty brake applications from a full bomb' -
that applies only to non-ABS braking operations. In a _real_ emergency,
ABS eats brake assist at 0.25 bomb/sec.

A bad bomb results in a potentially LETHAL vehicle. True, you can drive
around and pretend there isn't a problem. Do me (and every other driver
you're likely to meet) a favour - take your car out on gravel or snow
and see how it stops once the ABS engages. Friendly tip - pick
somewhere without too many trees, and lay a plastic sheet under your
Phil- Don't be mealy mouthed, why don't you say what you really MEAN!!
