Am having a problem with soft pedal on 2005 9-3 (2.0T) convertible (47K miles). Also, pedal goes almost to floor if you apply steady pressure. Dealer replaced hydraulic unit and master cylinder but problems persist. Indepedent SAAb mechanic says there is a problem. SAAB Tech services says all sport 9-3s do this due to dual piston brake booster. ANy thoughts would be appreciated. Thanks.
