The wear from the initial size of 14 mm in this case is so great that all four front pads should be replaced. On vehicles with ASR, wear sensors are also installed on the rear wheels. When installing new front pads, always check the condition of the rear pads.
Sequence of work
1. Remove the corresponding wheel.
2. ahead: The minimum thickness of the overlays is 2.0 mm. If the difference in pad thicknesses is more than 2.0 mm, disassemble the caliper bracket or check the pad guides.
3. Behind: Minimum lining wear level 2.0 mm. The thickness of the new pads is 11.0 mm.
4. The pads should be replaced if they are oily.
5. Warning: If the pads are not replaced in a timely manner before the minimum lining wear of 2.0 mm, the stroke of the brake piston will be too long, as a result of which the entire caliper may fail.
