Re: Replaced bomb - no problem now

["Fred Munro" <munrof@isys.ca>]

Hi Zsolt;

    Do the "bomb" test. Run the engine for several minutes, shut it off, and
pump the brakes until you feel the pedal get hard. Count the number of
pumps. If you get 10 or less, you need a new bomb. You should get 30-40 with
a good bomb.
    The brake light usually doesn't start coming on until the bomb is really
bad (1-3 pumps). At this point the "brake" light will flicker under heavy
brake application or may stay on for 30 seconds or so when you first start
the car. When this happens, the car is dangerous to drive - you will lose
brake assist in an emergency stop.
    If you do not have assist when you first drive your car an the "brake"
light does not come on, check that the hydraulic pressure sensor connectors
are clean and in place and that the bulb is not burned out in the dash. This
is a critical warning system on these cars.
