Hello together, about 1.5 years ago I renewed the brake pads at the front of my KA (accessories ). Since the pads are on it, it “cracks” every time I step on the brake. The new change on original parts also did not bring any improvement. When looking more closely, it was also clear where this came from: The pads have around 1.5 mm air in both directions and beat each time when braking against the coating carrier. If the rust had been violently attacked, I would still understand that. -But it’s not. Everything is fine from the brake performance. But the “crack” annoys me without end. Has the problem ever occurred or known to you !? Already thanks for your answers and experiences !!
