Well, It is my third time fixing this problem. The first time they resurfaced the routers and drums. The 2nd time they could not find the problem. Now the third time, It happened twice this week! The brakes were warped out, so I did a whole new break set up. New routers, drums, pads, full cleaning and checked brake lines and etc. The brakes are about 4 months. Some times the car would not stop, the brake pedal starts be be choppy, grinding noise begins and the car would not stop at all. I pushed the pedal all the way to the floor and tried pumping it and nothing helps. It happens most of the time when I stop at a stop sign while turning or in the parking lot. My suspension is about 7 months old, Monroe Sensa trac struts and springs, new Oem strut mounts etc. Any body else had this problem. Last night was horrible, I tried stopping at a stop sign while it was dark out, the road had little view and It would not stopped. It stopped in the middle of the road, good the road was not heavily driven at that time.
