Power Assist Brake Vacuum problems of the 1999 SAAB 95

1999 SAAB 9-5 has a faulty master cylinder, and vacuum booster which both had to be replaced at owners expense. In the past the consumer had to replace the water pump. Heater fan motor, thermostat. Leaky sunroof, battery, battery cables and numerous light bulbs.

Brakes failed on 1999 SAAB 9-5. Problem was due to a vacuum failure in the brake system. Apparently the vacumm pumped oil into the brake booster thus causing the brakes to fail. Fuel storage tank has had a leak in the upper seam which emits gas fumes when the tank is filled. I understand this has been a persistent problem with the SAAB fuel tanks.

Vacuum brake booster developed an internal leak, causing momentary loss of braking action when first stepping on brake pedal during an emergency stop. During "normal" braking the brakes worked fine. Important!. . . The big danger here is that you don't know there is a problem with the booster till you have to make a quick stop where you need to jam on the brakes quickly!! you suddenly fine there is virtually no brakes for a second or two!! in normal braking they work fine.
