I jumped in the heap yesterday and pulled out of my parking lot, when I hit the brakes to wait for passing traffic, the brakes grabbed really hard then the brake pedal went right to the floor. When I started away again, there was a weird scrapping grinding noise coming from the right hand side. The grabbing brakes usually happens when the KJ is sitting in the rain, then when I drive it the first thing in the morning, the grabbing happens. This time the pedal fading away is something never experienced before. Weird thing is that the brakes worked fine today??? Anyone have this happen before?
