What to pay attention to before and after replacing the brake pads

Replacement process:

First remove the tire, loosen the caliper body fastening screw, remember to check the screw and the caliper body sliding guide rod, clean the mud and oil on it, and apply lubricating oil for maintenance. Remove the old brake pads and check the degree of wear of the brake discs to see if there is any ditching. If the one side is 3mm deep, there will be serious wear and tear, and the brake discs need to be replaced at this time.

Install the brake pads and all the brake parts to reset the tires. When installing the tire screws, they must be tightened diagonally to protect the tires and brake hubs. At the same time, check whether the tire surface and edges are worn. Normally, it is recommended that the left and right wheels can be replaced regularly, which will help prolong the service life of the tires.
