About this product

GM Genuine Parts Brake Hydraulic Lines are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These are quality reinforced lines that carry fluid within the brake system. 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. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

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.
