MAINTAINING YOUR VEHICLE 335 Brake and Power Steering System Hoses When servicing the vehicle for scheduled maintenance, inspect surface of hoses for evidence of heat and mechanical damage. Hard and brittle rubber, cracking, tears, cuts, abrasion, and excessive swelling suggest deterioration of the rubber. Particular attention should be made to examining those hose surfaces nearest to high heat sources, such as the exhaust manifold. Inspect all hose clamps and couplings to make sure they are secure and no leaks are present. NOTE: Often fluids such as oil, power steering fluid, and brake fluid are used during assembly plant operations to ease the assembly of hoses to couplings. Therefore, oil wetness at the hose-coupling area is not necessarily an indication of leakage. Actual dripping of hot fluid when systems are under pressure (during vehicle operation) should be noted before hose is replaced based on leakage. NOTE: Inspection of brake hoses should be done whenever the brake system is serviced and every engine oil change. WARNING! Worn brake hoses can burst and cause brake failure. You could have an accident. If you see any signs of cracking, scuffing, or worn spots, have the brake hoses replaced immediately. Brake Master Cylinder The fluid level in the master cylinder should be checked when performing under hood services, or immediately if the brake system warning lamp shows system failure Be sure to clean the top of the master cylinder area before removing the cap. If necessary, add fluid to bring the fluid level up to the requirements described on the brake 7
