About this product

ACDelco GM Original Equipment Brake Hydraulic Lines are quality reinforced lines that carry fluid within the brake system, and are GM-recommended replacements for your vehicle's original components. The hydraulic fluid must travel to the wheel brakes from the master cylinder. It does this through brake lines or pipes and brake hoses. Brake lines and hoses are designed to withstand high pressures, and these brake hydraulic lines have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

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:

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