Candidate cause (the documents say what to do)
Brake pipe (brake line) corrosion and rupture
The pipes' steel-copper construction is vulnerable to galvanic corrosion if exposed to the environment.
NHTSA found the failures came with general excessive corrosion over most of the pipe assembly and appear to be expected wear-out of the coating in severe-corrosion states.
How to tell
Brake warning / Service Brake System
What to do
- In the joint inspections, scaling or flaking corrosion was taken as indicating the onset of metal loss and given the second lowest ranking (2); a leaking or previously repaired pipe was the lowest (1).
- GM noted that pipes with excessive flaking corrosion can only be fully evaluated, including remaining service life, by removing them, cleaning off the corrosion and sectioning them to assess remaining wall thickness.
- The inspections found no specific location where corrosion was visually more severe and no pattern between vehicles.
- Service records of incident vehicles also indicate that repairs are not isolated to a specific location or brake pipe.
- GM recommends replacing the entire set of pipes whenever any pipe leaks or is corroded enough to need replacement.
- On June 28, 2013 GM released 66 new part numbers for servicing brake pipes in 1999-2007 GMT800 pickups and utility vehicles.
Caution: Analysis of repair records indicates that consumers often elect to repair only the failed circuit.
