Checking the thickness of the brake disc (Mitsubishi L200 4)

1. Using a micrometer, check the thickness of the disc at 8 points with a difference of 45' and at a distance of 10 mm from the outer edge of the disc. Standard value: 28.0 mm, limit value: 26.4 mm.

• the difference between values (at least 8 points) should not exceed 0.015 mm.

Attention:

• when installing a new brake disc, grind it on a special device to achieve the standard value; otherwise the disc runout will be higher than normal, which may lead to vibration;
• to avoid deformation of the rotor and careless grinding, install washers under the nuts on the brake disc side (see figure); install all nuts and tighten them diagonally (crosswise) to a torque of 100 Nm.

2. If the disc is thinner than the minimum value, replace it. If the thickness difference in different places of the new disc exceeds the specified value, grind it with a special device, and then check the thickness again.
