A Genuinely Important, Honest Clarification Worth Knowing — BMW X5 Brake Discs
If a vibration under braking has been diagnosed as warped discs, this is genuinely worth knowing: what's commonly described as "warped discs" is, in reality, almost always caused by uneven deposits of pad material on the disc surface, since cast iron itself is genuinely difficult to warp under normal driving conditions.
It's also genuinely worth knowing a useful fix worth trying: thoroughly cleaning the mating surfaces between the wheel hub and the disc, or better still fitting new hubs entirely, has been documented resolving this kind of persistent vibration.
