Hi,
I have a totally stock 2005 evolution. I have been using the brake very aggressively over the weekend. On Saturday, I noticed the brake pedal went very spongy and the brake power was greatly reduced. I thought may be mositure got in my brake system, and cooked my brake fluid. So I bleed the brake fluid with ATE superblue which is DOT 4. The brake pads are fine. On Sunday, the spongy feeling can back and again I lost brake power. This time, when I pumped the brake once, then brake. The spongy feeling went a away momentarily. Also when the car is still, if I put my feet on the brake pedal with just the weight of my leg, the brake pedal will sink down very slowly. Someone told me that it is a sign of leaking brake cycliner. Have anyone experienced this? Or can anyone shed light on this problem.

Thanks alot.

Jim
