BRAKE SYSTEM SERVICE BRAKE LINES AND HOSES LESSON ONE-MODULE 2 Typical Brake Lines and Hoses Item Description 1 Brake Line Junction Block 2 Differential item Description 3 Metal Brake Lines 4 Rubber Brake Hose Brake lines are subject to the same high pressure as other parts of the hydraulic system. This requires that brake lines and hoses be tough and durable. Metal brake lines are made of double-walled steel tubing. If any section of a metal brake line is damaged or weakened by rust or corrosion, that entire section of line must be replaced. Rubber brake hoses allow movement of the front wheels for steering and suspension action, and rear wheels for suspension action. As with metal brake line, rubber brake hose cannot be repaired and must be replaced as a complete unit. Brake System Diagnosis and Repair September, 2005 69
