Salt Rusts Out Brake Lines in Chevy and GMC Trucks
Brake Line Corrosion: Protect Your Vehicle with NH Oil Undercoating
The National Highway Traffic Safety Administration (NHTSA) has received thousands of complaints from Chevrolet and GMC truck owners about brake failures caused by corroded brake lines. Most complaints originated from northern states where vehicles are exposed to saltwater every winter. The affected trucks span model years 2000 to 2009.
General Motors (GM) has not issued a recall, citing rust as a known cause of equipment failure. They attribute the problem to “liquid salt” used for deicing in snowbelt states. GM offers a “deeply discounted” solution—a brake line replacement kit with nylon-coated, rust-resistant lines. However, even at the discounted price, the fix costs $500, and that’s just for GM trucks. Owners of other makes, such as Toyota or Mazda, or those with rust damage beyond brake lines, may face significantly higher repair costs.
The Better Alternative: NH Oil Undercoating
Fortunately, there’s a better way to prevent corrosion:
NH Oil Undercoating. This treatment has been proven to dramatically reduce corrosion-related repairs and extend the life of vehicles. Unlike GM’s solution, NHOU protects against all types of corrosion caused by deicing materials—not just rust.
How Deicing Chemicals Affect Your Vehicle
Modern deicing mixes contain a variety of chemicals, from table salt to beet juice to magnesium chloride. Each of these compounds impacts your vehicle differently, and their effects extend beyond steel to aluminum and even plastic parts. GM’s nylon-coated brake lines, while resistant to rust, can still degrade when exposed to magnesium chloride and other deicing chemicals.
Comprehensive Protection with NH Oil Undercoating
NHOU treats all the surfaces of a vehicle’s undercarriage—including brake lines—creating a barrier that sheds foreign substances and resists decay. A professional RS3000 application costs less than GM’s brake line fix and provides comprehensive protection, including safeguarding nylon-coated lines from chemical breakdown.
