“The brake peddle is too small, it feels like my foot is going to come off of it or miss it. Some time's I lose a second or two trying to locate it with my foot, very frightening, and dangerous Every vehicle I have ever owned had a brake peddle twice that size. Yes it's a mini van, but the brake peddle does not need to be mini. This vehicle can carry 8 adults with lots of extra room, it should not even be classified a mini van. The brake peddle is less then 4 inches wide. Please look into this dangerous issue. Photos attached.”
