Good Maintenance Practices:

  • The following inspections and maintenance procedures can help prevent potential brake problems:
  • Check brake fluid level at every oil change. Replace fluid according to owner's manual recommendations.
  • Calipers and wheel cylinders should be checked every brake inspection and serviced or replaced as required.
  • Inspect the brake lines for rust, punctures or visible leaks (You may be able to do this, but consult a qualified technician if necessary).
  • Check the thickness of your brake pads.
  • The following should be conducted by a qualified technician:
  • Inspection of the brake hoses for brittleness or cracking.
  • Inspection of brake lining and pads for wear or contamination by brake fluid or grease.
  • Inspection of wheel bearings and grease seals.
  • Parking brake adjustments (as needed).

Troubleshooting Tips:

  • Brake rotor signs of wear include:
  • Visible ridges on rotor surface.
  • Chirping, grinding, or squeaking noises when braking.
  • Difficulty stopping the vehicle.
  • A low or sinking brake pedal.
  • Braking causes the pedal and/or steering wheel to pulsate/vibrate (not to be confused with normal ABS operation.
  • Vehicle pulls to the left or right when brakes are applied.
