Greetings Maybe someone can help me with my braking problem. I have a 190 DC with EZ. 1965. Front discs, rear drums. Despite multiple venting I obviously still have air in the system. Can pedal up to the. floor. If I quickly “pump”, I have a normal pressure point, which also does not change when I stay on the pedal. Drum brake pads are set, hand brake also. Have “classic” with a second man unaired, once first the Disc brakes, then the drums, a second time first the drums – longest line – and then the discs. Then I tried with a one-man vacuum device. Each time only bubble-free brake fluidity came, and each time the condition of the brake rack has not changed. What am I doing wrong, or what am I missing? Thank you for your advice.
