I have a 2005 Dodge Neon SXT.

When I am slowing to a stop the brake pressure is greatly reduce and the brake pedal goes to the floor, at higher speeds I do not have this problem.

This problem started 15 min ago.

I have checked the brake fluid and it is clean and it is filled to the line.

I had the front disk brakes replaced about three weeks ago and the rear pads did not need replacing.

I do not see ANY leaks on the ground in my parking space.

I have searched online and found this possible solution "the A module attached to the ABS unit in the engine compartment needs to be changed".

Based on your knowledge of braking systems and Dodge cars what do you think is the problem?
