So not b body related. I picked up an 02 dakota about a month ago. I dont like "newer" vehicles but the guy that owned it couldnt drive anymore and sold it to me for $700. The trucks in real nice shape but the brakes were spongy as all hell. I would get nothing out of the pedal and then all of it at once. I pulled the tires and all pads/shoes, rotors/drums in good shape. All the soft and hard lines i can see until it goes into the frame are in good shape and dry. Wheel cylinders and calipers dry on the line side and on the piston side. So i replaced the master cylinder and bled all the fluid in the system through. While bleeding the pedal goes to the floor for every side except the rear driver. The pedal hardly goes half way down. Anyhow i get a nice rock hard pedal when finished. Over the course of a week or two the pedal slowly goes right back to being mushy and having a hard time stopping. Feels like air. So i bleed ONLY the rear driver side and it goes back to a hard pedal feel. Right wheel cylinder is dry but i enternained the idea that its somehow sucking in air so i pump up the brakes and crack the line on the back of the cylinder. Still the pedal only goes down halfway. Ive never lost any fluid from the system. Sorry for the longwinded question but im stumped as to how air is getting into only this one side of the brakes.
