“If we can’t fix it.....  It ain’t broken”

Q: Why do brakes squeak?

A: Today’s cars are equipped with front wheel disc brakes; some models even have 4 wheel disc brake systems. Disc brakes work much like a modern bicycle’s brakes. Brake squealing and noises are common with various causes. Most often it is caused by dust and high frequency vibrations of the brake pads, much like the way a cricket makes noises by rubbing its legs together. Worn brake linings also tend to be noisy. Brake systems should be checked regularly and worn parts replaced before ruining expensive calipers and rotors.

Q: I hit a curb. Should I have the alignment checked?

A: Yes, often a little bump like that gets forgotten, especially if the car handles the same. Today’s cars are lighter with fewer and smaller suspension components and therefore less forgiving. If damage goes unnoticed, new tires may be needed. Look closely at the tread for uneven wear patterns or bald spots. Checking tire pressures helps tires last longer, improves handling and fuel economy. It’s important to set tire pressures at or just below the maximum rating on the tire.

Q: Does brake fluid really need to be changed?

A: The average driver uses their brakes 75,000 times per year and takes for granted that they’ll work every time. Today’s brake systems are hydraulic and use brake fluid which is hydrophilic, meaning it can absorb moisture from the air. Once the hydraulic system has moisture in it, corrosion takes place and brake components fail. Brake fluid should be flushed periodically to keep corrosion under control. This procedure is not expensive and is included in many preventative maintenance schedules. Brake fluid should be handled with care. It will melt plastics and remove paint.

Q: Why should I change my timing belt?

A: Most of today’s engines use timing belts, and are an important preventative maintenance item. In yesteryear they were made of metal and called timing chains. As engines became smaller and lighter, rubber belts replaced the heavier chains that had to be lubricated. The belt deteriorates with heat and age and lasts about 60,000 miles or 5 years although some makes have increased the life expectancy. The timing belt's job is to keep moving parts, primarily valves and pistons, in time with one another. If the timing belt is not replaced, it will eventually break, leaving you stranded, and on some models causing further engine damage which can be extremely expensive to repair.

Q: Why can’t I use plain water in my radiator?

A: Your car's engine makes enough heat to destroy itself so a cooling system is needed. Antifreeze mixed with water at a 50/50 ratio provides freeze and boiling protection. Too much antifreeze can cause heat transfer problems which can result in overheating. If you experience overheating, turn the a/c off and the heater on to help remove heat from the coolant. If the engine temperature light comes on or the gauge goes into the red zone, the engine should be turned off quickly and allowed to cool down to avoid costly engine damage. Plain water will start a rust process that is almost impossible to stop. Rust particles deteriorate the entire cooling system, water pump, radiator, hoses, thermostat etc.

Q: Does my car have to go back to the dealer for all services?

A: Preventative health care is important for peak performance and longevity. Preventative maintenance for today’s hi-tech cars helps keep small problems from becoming large expensive ones. Most new car warranties are affected by scheduled preventative maintenance, meaning that maintenance must be done in order to keep the factory warranties in affect. New car dealers would like you to believe that they are they only facilities that can perform these services. This is not true. Anyone can perform the required services, as long as the parts used are Original Equipment quality and all maintenance is performed on time per the manufacturers recommended schedule.
