Question: Anyone who has the push start button, notice that if the truck hasn't been started in about 2 -3 days when you push on the break peddle it feels like it's very hard and it's right to the top, can't push it down like normal?
Mine does it where th brake pedal gets hard after sitting a couple days. Its the vacuum leaking out if the power brake booster. I have had other cars/trucks do the same thing, but you notice it more with the pushbutton start since you have to push the brakes to start it.
Not sure if there is any spec on how long the brake booster has to hold the vacuum, seems like sitting 3 days is when I notice the pedal getting harder when starting.
