Brake fluid" knowledge of the car

Automobile "brake fluid" knowledge

Automobile maintenance supplies in the "brake fluid", also known as brake fluid, the following a few charts for you to introduce, automotive hydraulic braking system in the role of brake fluid.

The above chart for the hydraulic braking system principle of operation, through the above chart is not difficult to see the driver step on the brake pedal, the master cylinder "liquid" through the pipeline was sent to the tire on both sides of the brake pump, through the brake pump piston to promote the brake friction pads to give the wheels to apply braking force, and what we call the "liquid" is the "fluid". The "liquid" is "brake fluid", the left side of the above figure for the disc brake, the right side for the drum brake. Today's passenger cars are commonly used is the disc brakes, the specific principle of the following figure.

The brake fluid reservoir, installed in the engine compartment, is generally located on the same side as the brake pedal.

The brake fluid reservoir cover, clearly labeled with the type of brake fluid to be used, must be replaced in accordance with the specifications of the type of maintenance, otherwise there will be a safety accident.

Finally, to introduce the testing equipment, it is called "automotive brake fluid test pen ', is now a necessary auto repair business a test tool, this equipment is mainly through the detection of brake fluid in the amount of water to determine whether the brake fluid can continue to be used, if the brake fluid once the water content of more than the standard value of the words, the brake fluid in the high temperature, high pressure, internal water began to evaporate, thus resulting in a brake fluid can be used. If the water content in the brake fluid exceeds the standard value, the brake fluid will start to evaporate under high temperature and high pressure, which will result in the phenomenon of "air resistance", leading to the brake system stagnation, or even brake failure and other malfunctions.
