One problem related to brake drum wheel cylinder has been reported for the 2006 Chevrolet Silverado. The most recently reported issues are listed below.
This vehicle has had multiple brake issues since new. First off, it goes through front brake pads and rotors too frequently. First replaced around 25k and again around 60k. This vehicle has mostly been used for long highway trips, NY to FL etc. , not around town. Used in rural area. Next, several brakes lines have burst and had to be replaced. The last incident luckily was in my driveway. Having dual brake cylinders on these trucks does not seem to help if a brake line bursts. I needed the emergency brake to stop it on almost flat ground. A recurring problem is with the abs. Evidently they rust easily, especially in salt belt states, then corrosion on the sensor and hub causes it to activate for no reason. It does not activate the computer control or give warning. It happens intermittently. I had to have one front hub replaced in 2013 and another in 2014. Now I am having to replace one of those again with the dealer recommending to replace both. The cost is over $750 per side. There were recalls on previous year models but not 2006. This is ridiculous and the brake line issue has been going on with Chevrolet for a very long time. I had to replace most lines on my 1996 Silverado. I can't believe that nhsta allows this to go on year after year. Nothing is more important than braking, nothing!.
