My father and I have a running disagreement over parking brakes. Are they necessary, or should I just stop it?
His driveway is relatively flat, but if he stops far enough forward, the front sits a few inches lower than the rear.
He shuts off his Silverado 1500, and throws it in park - no parking brake. He steps off the brake pedal, and I hear a nice lurching noise as the weight of the truck comes to rest against the pawl in the auto box - ping!
I've explained this, but he's not moved. Does he risk a costly repair by scoffing at such a simply component, or am I just complicating the issue?
How can I convince a nonbeliever?
