Servus together, I have a question about braking airing. Recently I bought an electric venting unit from the company Manotec and worked with it for the first time yesterday. A Opel Movano B was ventilated. It worked wonderfully in itself, but after the venting the brake pedal had to be “pumped up”. That means it fell until shortly before the ground and came back again. With every single pump it got harder and came back again and again. Overall I have the approx. five times gemac Ht and now there is also a nice pressure point. It also brakes perfectly. The ABS also works. After the test drive with ABS brake I aired again, but the same behavior. The car drives and brakes perfectly, just like before however I wonder if this pumping is normal or can still be air in the system? Did anyone ever have that? Thank you very much.
