Before talking about the reasons, let me introduce you the working method of brake. With the vacuum assistance from the engine, general brake pump put forward the brake oil in the oil hose. Then the brake oil deliver the pressure to each brake branch pump at a high pressure. In the meantime, the piston force the brake rubber block and the brake disc wear each other. Then the wear cause brake force and then make the speed down, until the vehicle stops.
Then Let’s analyze why we need to change brake hose.
Rubber hose are the easiest to cause the brake pressure reduce. Because rubber has great elasticity. When press the brake disc, the oil pressure rises suddenly. Then part of the pressure begins to expand. Thus the inner size is force to expand. The pressure in the brake oil line reduce because of such reason. Then it cause brake force reduce and the brake time longer, the brake distance is longer as well.
This is an huge risk for safe driving of vehicles, especially brake in a high frequency and high strength situation. The best way is to use a metal brake hose instead of rubber hose. The inner tube of metal brake hose is PTFE, which is much more better than nylon material. Besides, the hose is covered with metal braid net. Such special structure is to limit the tube expand, so that the brake force will not lose because of expansion.
In order to keep the brake system work well and guarantee the safe and reliability, you should check the brake hose regularly. While the common problems are aging and leakage. As a professional supplier, OrientFlex suggests you check your brake hose every year and change a new one every 3 years.
