The symptoms of a faulty motorcycle brake pump are as follows: 1. Shaking when braking: This phenomenon mostly occurs in older motorcycles due to prolonged use and significant wear. It is recommended to consider using a lathe polishing process or replacing the brake pads (for older vehicles). 2. The direction tends to veer to one side: This is commonly known as 'brake pull,' and the main cause of this issue is uneven force applied by the left and right brake calipers on the brake pads. In this case, the caliper needs to be replaced. 3. Brake does not return: It is necessary to check if the brake fluid is insufficient; if there is oil leakage at the brake caliper, pipelines, or joints; or if the master cylinder or caliper components are damaged. 4. Reduced braking force: Possible causes include insufficient hydraulic pressure in the caliper or master cylinder, which may indicate oil leakage; brake system malfunction; or air leakage in the brake pipelines, requiring repair.

What Are the Specifications and Models of Grease Fittings?

Common types of grease fittings: Straight pressure grease fittings M6M10×1. Angle pressure grease fittings M645°M10×145°. Each nominal diameter corresponds to an outer diameter, with the inner diameter varying according to thickness. Pipes are categorized into imperial and metric pipes. For a pipe with a nominal diameter of DN100, if it belongs to the international standard series (commonly known as imperial pipe), its outer diameter is 114.3mm. Below are precautions for cleaning grease fittings: Monthly greasing: It is best to apply grease once a month. Otherwise, if the shaft pin rusts completely and becomes immovable, it is usually due to the operator not applying grease diligently. Sealing gaps tightly: Sand, gravel, and other debris from construction can enter the gap between the oil seal and the pin sleeve. Generally, the gap should be tightly sealed with wire, plastic hose, or inner tube. Clean before assembly: Remove impurities, gravel, and dust before installing the new replacement parts.

What to do if the b13bcf2 multi-collision brake is not functioning?

b13bcf2 multi-collision brake is not functioning, it is recommended to go to a 4S shop to repair the airbag control module. Below is relevant information about the automotive airbag system: Introduction: Abbreviated as SRS, it refers to the inflatable airbag installed in vehicles, which deploys instantly during a collision to provide cushioning and protect the safety of the driver and passengers. The airbag must be used in conjunction with seat belts to achieve its protective effect. Working principle of the airbag: When the impact sensor detects a collision, the relevant control system determines the severity of the crash and decides whether to trigger the inflator. The inflator module is typically composed of a gas generator, such as gasoline or explosives, combined with an ignition device. For safety during disposal, the airbag is usually only detonated at high temperatures. Since the collision process is extremely brief, the airbag typically takes about 25-35 milliseconds from triggering to complete inflation. If the inflation process takes too long, it will lose its effectiveness.
