Where the brake hose is？
The wheel is near the brake
The brake hose is located near the brake near the wheel and connects the brake to the brake fluid storage tank. Brake hose is a vital component of the automotive brake system, and its location is crucial. It is located behind the brake drum, that is, where the handbrake line is, if it is a disc brake, it is above the pump. The service life of the brake hose is limited, because any problem with the brake hose is very deadly, so it must be replaced every 30-40,000 kilometers. Brake hoses age over time during use, so they need to be replaced regularly to ensure the proper operation of the car's brake system.
The outer rubber of the brake hose is damaged. Should I replace it?
Requires
The outer rubber of the brake hose is damaged and needs to be replaced in time. Brake hose is an important part of automobile brake system, its external rubber layer damage may affect its performance and safety. Here are a few situations where brake hoses need to be replaced:
Brake tubing joint rust: joint corrosion rust, serious will lead to joint fracture, and then affect the normal operation of the brake system.
Brake tubing body bulge: In continuous braking or multiple emergency braking, the hose is under too much pressure, the tube body bulge will occur, although this bulge will not burst immediately, but there is potential danger.
Brake tubing body cracking: rubber has a certain service life, even if the brake hose has never been used, there will be cracking, especially when using inferior hose, the cracking will occur faster.
Brake tubing appearance scratches: in the process of car driving, the brake tubing is easy to appear friction, scratching, the original brake tubing due to material problems, the thin tubing layer is easy to appear large wear, resulting in oil leakage.
Brake tubing body oil leakage: When the brake hose oil leakage phenomenon, it indicates that it has been in a very dangerous state, need to be replaced immediately.
In addition, the brake tubing is mostly metal hard pipe, and the hose connected with the four calipers is also nylon braided, because the brake fluid is very corrosive, can not use ordinary rubber tubing. These tubing are pressure resistant standards, as long as it is not damaged from the outside, it will not break. However, when the outer skin of the brake tubing breaks, if there is no oil leakage, the vehicle can continue to be used, but it is recommended to replace it in time. This is because the brake fluid is extremely corrosive, and the hose connecting the four calipers cannot use ordinary rubber tubes.
The sign of a broken brake hose
The performance of brake hose failure mainly includes brake brake, brake foot feeling soft, brake distance lengthening, pipe cracking, pipe oil leakage, pipe burst, pipe scratch or scratch, joint rust, bulge, cracking, scratch, oil leakage, etc.
Brake hose is an important part of automobile braking system, its state directly affects the braking performance and driving safety of the vehicle. When the brake hose fails, the vehicle may appear in the following ways:
Brake bias: This is caused by unequal braking force on both sides, which may be caused by unilateral brake hose damage (such as dented, blocked, oil leakage) or air resistance.
Brake foot feeling soft: brake oil containing moisture or insufficient brake oil will cause brake soft, this may be because of the brake hose leakage resulting in less oil.
Longer braking distance: When braking, the brake hose will expand due to the sudden increase in oil pressure, weakening the braking force in the front segment, resulting in longer braking distance.
Pipe cracking: this is a typical rubber aging phenomenon, due to the chemical reaction of rubber with ozone in the air, resulting in varying degrees of aging of rubber.
Pipe body oil leakage: the main reason is that the inner core of the joint is loose or the joint connection position for a long time bending around the outer rubber layer or even the inner rubber layer is broken.
Pipe burst: This is a typical quality problem, may be due to substandard performance, failure to meet the brake hose required to burst pressure standards.
Pipe body scratching or scratching: This phenomenon is more common in bad road conditions and man-made damage, especially in the frequent activity of off-road vehicles on unusual roads.
Joint rust: Most of the joints of the brake hose are made of iron, and under natural conditions, iron will oxidize with water in the air, resulting in corrosion and rust.
Bulge: The brake hose bulge is potentially dangerous and will develop into a brake tube burst, and once the brake hose bursts, it will directly lead to brake failure.
Cracking: Even if the brake hose has never been used, it will crack due to aging of the rubber.
Scratches: In the process of driving, the road surface will be uneven and potholes, so the brake hose will inevitably bump and wear. There is also the possibility of oil leaks and blowouts if the wear is severe.
In order to ensure driving safety, it is necessary to check the brake hose regularly, and once the above situation occurs, it is necessary to repair and replace it immediately.
