14. Friction Wear on Brake Pads

The friction on your brakes and clutch results in brake and clutch wear. If used improperly, excessive wear to the brake pads and clutch can occur. To avoid this:

  • do not ride your brakes
  • do not drive with your clutch partially engaged (depressed)
  • use your lower gears to slow the vehicle on downhill grades (downshift)

  • Friction can also cause wear, and possible destruction, of other parts of your vehicle, such as bearings and internal engine parts. To lower the friction on these parts, manufacturers use a lubrication system to provide a thin film of oil or grease between the moving parts. This is the same thing that happens when you squirt oil on a sqeaky door hinge.
