Install only brake hoses recommended by the factory.
After installation, check without load (the car is lifted), whether the hose follows all the movements of the wheel and does not rub.
Caution: Do not allow brake hoses to come into contact with oil or kerosene, do not coat them with paint or underbody protection.
Remove air from the brake system.
