The brake hose is connected via the hose fitting. Therefore, when the automobile is braked, braking frictional heat is conducted to the end of the brake hose connected to the wheel caliper through the hose fitting.
Braking frictional heat poses no problem during normal braking, but when severe braking is repeatedly performed, it generates a large amount of heat and causes local thermal deterioration of the brake hose.
This is because the hose fitting is made of a metal with good thermal conductivity.
