Auto Repairs how to Fix a Leaking Brake Line
Knowing how to fix a leaking brake line can save money and prevent an accident. A leaking brake line is just one use of the brakes short of a total brake failure.The first sign of a leaking brake line is a change in brake pedal feel or the pressure required to stop the vehicle. Most people who are knowledgeable about brakes will proceed to the brake master cylinder reservoir and check the fluid level. Topping off the fluid will restore proper brake and pedal pressure.A little knowledge is a dangerous thing. After topping off the fluid each wheel of the car and all the brake line fittings should be inspected. Driving the vehicle without doing this inspection can result in total brake failure.Check the inside of each wheel with a flashlight. If there is a small amount of oily looking residue on the tire or around the brake lines or fittings there is a leak or a failing brake cylinder. Both disc and drum brakes operate on the same principle using hydraulic lines and cylinders with a small piston in them. When the seals on the cylinders become worn, they start to leak brake fluid.On cars that are left parked for months at a time, it is possible for a small amount of fluid to evaporate without any apparent leaks in the system. This can be particularly dangerous because failure is often sudden. All vehicles need to be driven at least once a week. Stored vehicles need to be thoroughly inspected.Vehicles that are purchased new but now have high mileage will be more likely to have a bad or worn brake line than a loose fitting. Used vehicles can have any number of circumstances that will result in a leaking brake system. New brake lines are often found with loose fittings. A slight turn of the wrench is usually all that is needed to correct the problem.Cars with a worn or leaking brake line will often have more than one. A thorough inspection of all lines and fittings should be done after any repairs or replacements.When all work is completed and all leaks are repaired or corrected the brake system has to be cleared of air or "bled." A professional should perform this procedure."Bleeding" brakes requires two people or special equipment to be done correctly. If the procedure is not done in a precise manner there will be low brake pressure and an accident could result.
