Hard brake pedal before starting
I've seen the thread regarding a hard brake pedal while driving. But I occasionally experience a hard brake pedal BEFORE starting my 2011 Limited 5.7. The brake pedal is never hard while driving, and it's only hard before starting after the vehicle has sat in the garage for a couple / few days. After the motor starts, the pedal goes down to normal "power-brake" feel. Any thoughts as to what's going on?
