Hello, I would urgently need some expert tips from you. The whole thing started with the fact that I recently noticed that my front brake is no longer fixed, that much of me by a clapping, when driving over small bumps. I found out that a screw has already loosened and that the brake was only sitting crooked on the disc and sanded the brake cheeks on the disc. I then renewed the complete brake caliper. This also works perfectly again, but I now have a very strong vibration in the whole front axle. This is expressed by a very strong flickering front light when driving fast. When driving slowly (approx. 30-50 kmH) the handlebar starts to shake extremely strongly when I release it. I had first read on the internet that this could also be on the steering head bearings and have already changed them, unfortunately nothing changed at all in the situation. my question about what it could be? Can a bent brake disc be the reason, purely optically I can find nothing. Or is it possibly due to the fork or the wheel bearings? Unfortunately, I can’t afford a repair in a workshop… Can you help me? Or give me tips on how to examine the individual components for functionality? Thank you for your help in advance!!!
