The brake system is an important guarantee for the safety of the car. The brake pads and brake fluid are the parts with relatively frequent replacement cycles, and they are also the parts that are relatively prone to problems. The following are the reasons for the inconsistent wear of the brake pads and the recommendations for the use of brake fluid.

1. brake pads wear inconsistently. For example, the right front wheel brake pad of the car is very good, and the left brake pad is worn out. What is the reason?

This is mainly because when braking, the brake guide pin of the left front brake cylinder is stuck (mostly due to dust and oil particles), causing the brake pads to rub against the brake disc. The front wheel brake of a car is generally a floating caliper brake, and its automatic return is based on a rectangular oil seal.

It is recommended to go to a professional auto repair shop or 4S shop to check the sub-cylinder dust cover and brake guide pin, remove and clean and add a small amount of grease. At the same time, it is recommended to do brake maintenance frequently to minimize the loss.

The normal use of 2. brakes is inseparable from brake fluid. What are the precautions for the maintenance of brake fluid?

Brake fluid is also called automobile brake fluid. Early cars used drum brakes that were mechanically braked. With the development of hydraulic technology, safe and reliable hydraulic brake system is widely used in automobiles.

Automotive brake fluid (brake fluid) is the fluid used in automotive hydraulic brake systems. When the driver steps on the brake, the force from the pedal is transferred from the piston of the brake master cylinder to the wheel cylinders through the brake fluid, so that the friction plates are expanded to stop the vehicle from moving forward. At that time, the return spring pulls back the friction plate to its original position. Brake fluid plays a role in force transmission in the whole process.

Brake fluid has water absorption characteristics. If it is not replaced for a long time, it will corrode the brake system and bring hidden dangers to driving. At the same time, after the brake fluid absorbs water, the boiling point will decrease, and it is easy to boil to produce air, which will cause the brake to fail or cause insufficient brake pressure, which will affect the braking effect.

Under normal circumstances, it is recommended that the owner of a friend, two years or 40000 kilometers to replace the brake oil. If it is detected that the water content of the vehicle reaches more than 5%, it must be replaced.
