There are several ways to reset the brake pump:
Use the master cylinder returner or wrench to rotate. This method is suitable for most models, and the master cylinder is returned by rotating it.
Use the diagnostic instrument to reset. If the brake pump pops out, you can use the diagnostic instrument to reset it. First, open the fuel cap of the master cylinder and remove the front tire, then use a flat screwdriver to push the brake pad inspection port to gradually retract the brake cylinder.
Manual reset method. In the absence of special tools, you can use needle-nosed pliers or other tools to hold the notch of the piston and rotate it clockwise to achieve the reset effect. Things to note when resetting the brake pump include: Cleaning impurities: If the brake cylinder cannot be returned, there may be an internal problem. At this time, the cylinder can be disassembled and the internal impurities can be cleaned, especially the key parts such as the piston, to ensure that there is no foreign matter. Observe the brake oil pot: When turning the nut, it is best to observe the brake oil pot to avoid overflow of brake oil due to the return of the master cylinder.
Through the above methods, the problem of the car brake pump not returning to its original position can be effectively solved, ensuring the safe driving of the vehicle.
