Next monday I’m getting the entire brake line system on my relatively new chevy truck replaced because it rusted out. The new lines are stainless steel and only cost $80. $1000 in labor. It’s a chronic problem in these trucks. At least nobody died when the brakes failed...
It’s the last GM product I will ever own.
I have a 14 year old Avalanche and it’s been a dream machine. Nothing but expected mileage replacements. Bought a Surburban for the wife 3 years ago, just oil changes so far. Sticking with Chevy myself. Previous F-150 and RAM were always in the shop.
Rust implies water IN the brake lines. Or was this external corrosion?
You live in the salt-on-roads zone?
Outside in or from inside out? They’re copper lined inside. Do you live in snow country?
