Hi Tim...
First...I've got a new address...I'm lucky I got this at all..should
be in the header.
The "bomb" is also known as the "brake pressure accumulator." I
believe that it's main function is to maintain hydraulic pressure
approaching the vicinity of 2500lbs...and to retain most of that pressure
even after a night in your driveway. The reason your light is going on
is probably because the diaphragm inside the accumulator is on it's way
out which I believe is much more a function of age than use...or miles.
Over night, you are probably losing pressure. After your car runs for a
few minutes, the pressure is restored and the light goes out. Here's the
caution: Under heavy and/or repetitive breaking (your 15 pump driveway
test) the "bomb" does not have enough reserve or is not able to maintain
the pressure that it should. You are now in what I consider to be in the
caution zone. If it is the bomb, it will need to be replaced fairly
soon. Do it now, get it over with, and be safe (got kids?). My
experience tells me that bombs are usually good for 4-6 years on average
(who knows). I do not believe that any "bomb" I've seen is a box...more
like an expensive WWII German hand grenade with a big bulge in the
middle. They should come in a velvet lined jewelry box for the roughly
$275 they charge (and that's a good price) expect an installing shop to
charge about $330-$350 which is reasonable. On your car you should be
able to get out of the whole mess for less than 4 bills. Placement of
most bombs is near the bottom of the engine compartment (listers?). That
sinking feeling test of yours: My experience has been that after pushing
a number of times you can push very hard the last time and feel an
unnerving pulsing as the pedal gravitates towards the floor. I'm
forwarding this to the Q-list so some other folks can critique it if I've
given any misleading info....as for install..I personally do not like to
do brake related work..it makes me nervous because I've had no good
trainer or mentor...so I part with the $45 labor for this messy and
critcal job....Good Luck!
Most good foreign parts stores carry Pentosin at about $17-18 a
quart. I have used Luca's version in the past with no ill effects for
$11 a quart (it's only green baby oil for chrissakes). You could take
the used Pentosin to a lab but that's undoubtedly overkill..you tell me
(listers?).
How's the rest of the car treating you?
Questions for you...where did you..and how much are you paying for
the Bently?
Is a car really yours until you've had sex in it?
