- 1). Wash your vehicle regularly, especially in winter climates where salt or de-icing agents are used on roads. Even in summer these chemicals remain on the roads and when wet can carry to the car's under body. Use a car wash that has an under body wash that reaches up from beneath the car into areas you might not be able to wash yourself. Washing helps keep corrosive or damaging contaminants off the car and its parts, including the brake lines.
- 2). Check your brake fluid levels regularly. Low levels can cause overheating to the system, breaking down the fluid. The more the fluid is compromised the more corrosive it will become, causing damage from within the system.
- 3). Use the proper tools when repairing your vehicle's brake system or lines. Scratches and abrasions on the brake lines' surface can open the metal to rusting or corrosion.
- 4). Replace your brake fluid at least once a year or have it tested to see if it needs replacing. All lubricants and fluids in a vehicle become less efficient over time, and brake fluid can become heated and "burned" just like engine oil. Bad brake fluid will cause damage to the system and corrode the brake lines internally.
- 5). Check the system regularly for leaks. Small leaks in the flexible lines around tires can cause corrosion in these areas. Be sure the system is not compromised by this type of damage, as it can cause further problems and more costly repairs if not corrected.
