A new waterproof brake base plate includes a base plate body; a connecting structure is provided on the base plate body. There are two left dust cover holes, and the two left dust cover holes are opened on the left side of the base plate body; there are two right dust cover holes, and the two right dust cover holes are opened on the right side of the base plate body. The dust cover is installed through the left dust cover hole and the right dust cover hole on the base plate body to play a good sealing role, thereby solving the problem that the brake of the car plays a waterproof role when wading, and mud and sand will not enter the brake, thereby improving the braking performance. The above patent has the following deficiencies in use: the strength of the connecting plate B is relatively low, and one end of the brake shoe will be rotatably connected to the connecting plate B. When in use, the connecting plate B will be subjected to a large torsional torque. Therefore, it is easy for the connecting plate B to break due to torsion at the connection with the base plate body, causing damage to the connecting plate B and affecting its service life.
