Brakes are Very Soft..

[Soccer21]

Ok, so my brakes are VERY soft..the pedal goes all the way to the bottom before braking occurs...The Pedal NEVER builds up pressure and this behavior is observed each time I try and brake.

I changed the rear pads, the front pads are like new. I also bled the brake fluid form each of the 4 wheels and made sure no air got back into the system.

Same problem again, except this time the brake fluid turned black..I assume some vavle/o-ring seal in the Master cyclinder gave out.

So....I got a new rebuilt Master Cyclinder from MAZDA..installed it last night..without a problem.

I tried to brake and STILL the same problem...

Could my ABS system be fouled? Can someone help me??
