Recently drove 2015 Silverado LTZ on long trip for vacation. Truck has right at 48,000 miles on it. Brakes started acting up as soon as I arrived.
I noticed the brake pedal acting up at a few red lights and then when we got to hotel the pedal went all the way to the floor before it came to a stop. Had it looked at by a mechanic. His computer showed a bad brake booster, so had that replaced and a new brake booster line, as well. Everything else looked fine. That made the issue better, but still having problems when in reverse and if the brakes are pumped a couple of times before coming to a complete stop. On the way home I finally got a service brake assist message.
Just wondering if if anyone else has experienced similar issues and what ended up being the problem?
