RE: The "Bomb" (was: Pentosin flush>

1) With the engine running, disconnect the brake booster return line
(the one that goes from the booster to the reservoir - DO NOT confuse
the lines, as you might visit the nearest hospital). There should be no
more than few drips, if the oil escapes in a continuous flow, the
booster is defective.
2) If the booster proves to be OK, run the engine for a minute then
switch off. Count how many times can you depress the brake pedal before
you lose the assist. Less than 10 times? Time for a new bomb.
