Hello people are new here maybe someone can help me. I recently bought a Suzuki GSX F 1100. I’m not a professional screwdriver but I can handle one or the other. Today I changed the coverings in the front and installed steel flex brake hoses. I also vented the brake system but it does not create any brake pressure. I don’t understand. If the system can be ventilated it would have to build up pressure. I would be very grateful for advice.
