It after vehicle is completely out of service, is measured at reserved measured hole using depthometer or vernier caliper, when measurement need to remove
The blocking installed on measured hole, because brake inside turns off cooling oil during the inspection process full of the cooling oil of circulation
The circulatory system, also have a large amount of cooling oil from measured hole flow out, the waste of cooling oil is caused, as cooling oil flows to ground
On, it will pollute the environment.Moreover, the data that operator is obtained by depthometer or vernier caliper measurement need again with operation
Data on handbook are compared, and just can determine that whether brake(-holder) block fails, since brake installation site is usually compact, In
In the case where not dismantling wheel rim, operator's available space is smaller, causes that measurement is difficult, time-consuming, and dismantling wheel rim will production
Raw extra workload and waste of time.
