Hello together, I have a problem and that my brakes self-braking. I had the problem that my car at the front right got the rim really hot and even started to squeak and very loudly. Problem was that the piston was completely rusted with the caliper and not really re-tried. Problem found, two new calipers bought and changed. Brake pads are also new and the disc is hardly worn out. Problem now, however, is that I notice that my car is very lightly braking itself. Rims are driving after 50 minutes, minimally warm, if you can call it warm. The brake disc is equally hot on both sides. At the back I also installed short new brake pads, caliper and two new brake ropes. Can anyone help me there? I thank you in advance.
