A) Jack up the front of the car.
b) Remove wheels.
V) Check the thickness of the brake pads.
- Minimum thickness - 2.0 mm
G) Replace brake pads as a set (right and left side at the same time), if at least one of the linings of the block has a minimum or smaller thickness.
2. Check the axial play of the brake disc.
A) Secure the brake disc by tightening the wheel nuts.
b) Install dial gauge
V) Measure the axial runout of the disc at a distance of 10 mm from the outer edge of the disc.
- Maximum axial runout - 0.05 mm
If the brake disc axial runout exceeds the specified limit, grind or replace the brake disc.
3. Measure the brake disc thickness.
Brake Disc Thickness:
- Rated - 28 mm
- Minimum allowable - 26 mm
- The minimum allowable after turning is 26.8 mm
If the thickness of the brake disc is less than the minimum, replace the brake disc.
4. Check up uniformity of wear of a brake disk.
A) Clean the surface of the brake disc in contact with the brake pads.
b) Using a micrometer, measure the depth of the recesses shown in the figure.
V) Subtract the minimum value from the maximum measured value.
- Maximum measurement difference - 0.015 mm
If the difference in measurements exceeds the established norm, grind the brake disc.
Attention: when turning a disc, do not allow its thickness to become less than the minimum allowable.
Note: wheel turning with removal from the car can lead to the appearance of axial runout, which is much higher than the allowable one. Carry out the groove of the brake disc without removing it from the car.
