With frequent use and sometimes according to the driving conditions and the type of load, the brake disc of trolleys reduces its power and makes the surface of the brake disc uneven. In these cases,
can generally be used to grind the brake disc using a disc grinder
as a method to restore the surface of the brake disc. But to determine the time
The following points should be considered for grinding the brake disc:
1-Disc thickness: To determine the permissible thickness for grinding the brake disc, one should refer to the trailer manufacturer's guide. If the thickness of the disc reaches the minimum allowed, the brake disc must be replaced. Some brake discs with high thickness and stronger structure have more number of blades.
3- Disc surface: If the surface of the brake disc is uneven and too dry, sharpening the brake disc can improve braking performance.
4- Amount of use: Depending on the conditions of use, the brake disc should be checked periodically to determine the need for sharpening.
In general, specialized repair shops usually use disc sharpening machines
< furnaces and according to the conditions of the brake disc, they offer customers to sharpen the brake disc. However, regular disk maintenance is recommended
