I have a 2000 dodge dakota slt with 4 wheel ABS and i have been fixing it up to get it road ready. I have been dealing with a very soft pedal on braking to the point where i thought my brakes were past the wear markers. I went to put new shoes on the rear today and found out they were fine and needed a little adjustment, after they got adjusted i bled the brakes and blew some air out of the lines and when i drove it again the pedal was still soft as room temp. butter. When i did a panic stop the pedal went almost all the way to the floor and then made this grinding clicking ratcheting sound and with every click the pedal sank lower and lower to the floor. i have no idea how to fix this problem and the abs module seems ok... but i have no clue on how to test any of the abs stuff. any helpful comments are welcome

 

The funky noises and pedal dancing on HARD braking is your ABS system doing it's thing. That's normal. (though scary the first couple times..... just keep pressure on the pedal, and the system will let you stop as quickly as possible. pumping the brakes at that point is actually counter-productive.)

If the pedal is just low, (excessive travel before it actually tries to stop the truck.) that's rear brake adjustment. If the pedal feels spongy, that's air in the lines. It's also possible the soft lines are breaking down, and they will then swell under pressure, which also makes the pedal feel wonky. Get a couple quarts of brake fluid, grab a friend, and flush the brake system good. Don't know if there is a specific procedure for bleeding the ABS module.
