On the 1999-2007 Chevrolet Silverado, gMT800 Silverados (and the related GM trucks/SUVs) in salt-belt states are widely reported to suffer rusted-through steel brake lines, leading to a sudden brake-fluid leak and loss of pedal/braking. NHTSA investigated ~6 million 1999-2003 GM trucks and SUVs after an owner petition; the agency closed it with no recall, concluding the coated-steel lines corroded at rates similar to peers. NHTSA logged 240 corroded-brake-line complaints for the 2004 Silverado/Sierra and 112 for 2006 alone. GM offered a pre-formed brake-line replacement kit via TSB (13-05-22-001) rather than a recall. Fuel lines on the same trucks rust similarly. Very high real-world demand because it is a safety failure on a hugely common older truck.

Common Symptoms

Soft / sinking brake pedal or pedal goes to floor
Loss of braking / longer stopping distance
Brake-fluid leak on the ground
Low brake fluid warning
Visible rust/scaling or weeping on steel lines
Fuel smell from rusted fuel line

How to Fix

Inspect all steel brake and fuel lines for scaling, pitting and weeping, especially over the rear axle and along the frame. Any line that is rusted, leaking, or that flakes under probing must be replaced — best practice is to replace affected lines (or the full set) with stainless-steel or coated pre-bent lines (GM offered a pre-formed kit). Do not drive a truck with a leaking brake line. Undercoating and washing the underbody after winter driving slows future corrosion.
