Hello, for a few weeks now, my omega (MV6, BJ 2000), which was newly added to me a few months ago, has experienced extreme vibrations during braking. Due to my guess on warped brake discs, I then measured their running schedule. The result was on both sides of the front 0.18mm flat beat (back 0.05mm). In the front too much flat beat…I thought I was wrong (it was funny that I never had to brake strongly since I had it). Yesterday I wanted my brake discs and pads on the r Renewing the front axle (Brembo). After I added it, I measured the flat beat again with my measuring clock. Result with the new discs: 0.25mm outside on the disc, even worse than before. The result was reproducible again and again with both new discs. Then I checked the wheel hubs for flat beat. Result: 0.1mm. So now the wheel hubs come new at the front, then everything should be right again. And now to the reason of my thread…The look of the verz The wheel hubs still shine pretty much and are therefore not very old, not to recognize manufacturers. Now you can see blue start-up colors that occur during overheating (Fig. 1). But where should the heat come from? Maybe from the now run dry wheel bearings, because their lubricant has apparently pressed down along the slit from the bearings (Fig. 2)? Have you seen this before? FG Konstantin
