The following should be conducted by a qualified technician:

  • 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.
  • 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:

  • Vehicle pulls to the left or right when brakes are applied.
  • Brake pedal pulsation (not to be confused with normal ABS operation).
