The brake system is an important guarantee of vehicle safety. Brake pads and brake oil are parts with relatively frequent replacement cycles, and they are also relatively prone to problems.
Firstly, brake pad wear is not permanent. For example: brake pad of car's right front wheel is very good, but left brake pad is very worn, what is reason?
This is mainly due to fact that when brake is applied, left front brake cylinder guide pin gets stuck (mainly due to adhering of foreign particles such as dust and oil), which causes brake pad to continue to rub against brake pad. brake disk. The front wheel brake of a car is usually a floating caliper brake, and its automatic return depends on a rectangular oil seal. It is recommended to go to a professional bodyshop or 4S to check slave cylinder dust cover, check brake guide pin, remove it for cleaning and add a small amount of grease. At same time, frequent brake maintenance is recommended to minimize losses.
Second, normal brake use is inseparable from brake fluid. What are precautions for servicing brake fluid?
Brake fluid is also called automotive brake fluid. Early automobiles used mechanical brakes with drum brakes. With development of hydraulic technology, safe and reliable hydraulic braking systems are widely used in automobiles.
Automotive brake fluid (brake fluid) is a fluid used in hydraulic braking system of automobiles. When driver applies brakes, force from pedals is transmitted from brake master cylinder piston to auxiliary wheel cylinders through brake fluid, so that friction discs expand to achieve purpose of stopping vehicle. ., return spring returns friction plate to its original position. Brake fluid plays role of power transmission throughout process.
Brake fluid has water-absorbing properties, if not changed for a long time, it corrodes brake system and creates hidden driving hazards. At same time, after brake fluid absorbs water, boiling point will decrease, and it is easy to boil to form air, which will lead to brake failure or insufficient brake pressure, which will affect braking performance.
Generally, car owners are advised to change brake fluid every two years or 40,000 kilometers. If a vehicle is found to have more than five percent water content, it must be replaced.
