The following are the symptoms: With longer braking distances (e.g. easy braking on the way to the red traffic light), you have to keep the pedal going to keep a constant braking performance. It seems like the pressure disappears with longer braking distances. However, if you push it through to the rear, it slows down so strongly that the ABS regulates. In case of jerky braking (driving braking) the pedal is completely normal and it immediately grabs the ABS. Brake fluid is changed without improvement. So far no leakage can be fixed. Brake discs and pads at the front new (Brembo) When fully crossed through to the stop and standing car, I have according to VIDA about 115 bar braking pressure. But really up to the stop. When the motor is switched off, the pedal becomes hard and when you kick it and the engine starts there may be some questions after it should be main minutes. Have tested on a slope whether the brake holds the pressure. But for that I have not stopped the pedal so easily, the pedal is kept on the exact.
