I bought my 06 Explorer with 12k miles. Soon after purchase, I noticed the brake pedal felt soft and seemed to require a longer stopping distance than my old Explorer. The dealer acknowledged a problem and replaced the master cylinder. The brake pedal then felt slightly better, but only for a short time. Since that time, there has been multiple times when I was attempting to brake for a turn but the vehicle did not slow down enough to turn, despite having the brake pedal almost to the floor. Most recently, when driving in snowy conditions, when the abs kicks in, it feels like the brake pedal cannot be pushed down and the vehicle does not stop, causing me to slide through a red light, despite going slow and braking a long distance before the light. The brake system on the Explorer does not feel safe and needs to be recalled!.
