Four problems related to brake foundation components have been reported for the 1998 Audi A4. The most recently reported issues are listed below.
In heavy rain conditions, brakes become unresponsive for appx 1-2 seconds, regardless of pedal pressure. I have been driving for 18 years and can attest that this is not a case of normal 'reduced effectiveness' associated with wet conditions. In certain conditions, the car will travel for 20-50 feet without any noticeable brake effectiveness. Yes, I do pump my brakes frequently under these conditions to clear excess water from the pads/rotors.
Vehicle experienced steering wheel and brake lock up. Mjs.
Brakes do not work in wet conditions!.
When parallel parking noticed difficulty in the steering, later noice broken wires at front of engine. Brakes have always required extra effort and performed poorly.
