I have a 2004 Dodge Dakota 3.7, rear anti-locks. My brake pedal goes to the floor, almost. I have replaced the master cylinder, brake booster & front pads. and replaced the bleeder screws. Front discs are at 24.75, min. is 24.50. Back drums are adjusted properly. What else could be the cause of the brake pedal going to the floor. Before I go any further, can you give me a direction to go. If it is the rwal module, can it be replaced by a dyier? Rear shoes are getting close to be replaced, but still have some life to them. I have no abs light or engine light on.

Being that you've open the system up to atmosphere, my first thought is air with in the system.

Spongey brake pedal indicates air is still in the lines. What condition are the hydraulic brakes lines and brakes hoses? Is it possible there’s a hole, damage, or rust causing line failure? Also, how did you bleed the lines when you swapped out the MC? I’ve worked on several vehicles where you literally have to bang on the calipers and drum cylinders to loosen any trapped air - during brake bleeding.

the original reason for me replacing the fore mentioned parts, was because of the pedal going to the floor, that is the problem. Every part I have replaced, has not changed the original problem, pedal going to the floor.

The issue may be that you corrected the cause of the original problem but in the process recreated it.
There is also a possibility one or more of the rubber hoses could be an issue.

when you replaced the master did you bleed it before you put it in because your suppose to bench bleed it first. then bleed the whole system after that. you would start with bleeding the abs system. then go to the right rear and bleed that one. next the left rear. then the right front after that the left front. if still have a no pedal try opening the bleed screw and have someone press the brake pedal to the floor and hold while you tighten it back up. that usually works for the garage i work for.
