My ABS light is coming on. I had my front and rear brakes done about eight months ago and at that time the brake fluid was also replaced. Before the light comes on the brakes on a little mushy, but brakes fine even with the light on. I have replace the relays inside the ABS unit and check the sensor in front and rear.

  If your brakes are mushy, you may have air in the lines. The ABS unit is a secondary pump. If you bleed the system, and its still mushy, then you may have a weak master cylinder.
