When I applied brakes my traction light came on and I didn't have any power to my breaks. I double pumped and they worked again, almost ran into a subway!!! this is very scary and I brought vehicle in and they could diagnosis a problem because it was intermittent. I have googled this and this is a severe problem when your brakes don't work and how do you fix them when the shop can't figure it out!!! it says it is a sensory issue, and feels like the abs are working when you are on ice, but this is happening on dry pavement.
