 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.
 [To original poster]
 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!!
