Have you ever wondered how your mechanic determines when it's time to change your brake fluid? If you don't know very much about cars, it's sometimes difficult to know what, exactly, your mechanic is replacing and why they are replacing it. You know that your brake fluid is important, but do you know exactly what it does?
To start, it's best to explain the mechanical process…
The term "horsepower" refers to the comparison of power between mechanical engines and horses.
In the 18th century, James Watt estimated that draft ponies could pull about 33,000 pounds per minute. He decided that if a mechanical engine could pull that much weight in one minute, it had the power of one horse.
New drivers are told to keep the tank full, top off the fluids and change the oil every 3,000 miles. This may have been drummed into you as a teenager and many people still abide by these recommendations even now. But did you know that changing the oil every 3,000 miles is not needed anymore?
